Centrifugal Brake System

Manufacturer & Exporter of Centrifugal Brake System. Our product range also comprises of Permanent Magnet Generator, Emergency Overspeed Governor and Permanent Magnet Motor.
In order to cement our reputation in the market, we are engaged in catering a wide range of Centrifugal Brake System. These systems are manufactured under the leadership of our industry experts using advanced ranking material and modernize technology in agreement with set business standards. Provided range is comprehensively cherished in the market for its salient features. 

Features:

• Surpass performance
• Application specific design
• Enhanced durability

Product Details:

• The brake, mounted on a shaft, starts to break a drive shaft at a defined speed. Centrifugal force causes the flyweights to lift from the hub so that their linings contact the inside diameter of the brake drum. This action creates a braking torque
• As soon as the speed of rotation of the system falls, the tension springsreturn the flyweights to their initial position. It is a fundamental principle of centrifugal brakes that they cannot break a system to a standstill, i.e. the system speed searches for an equilibrium condition between the speed determined by load torque and braking torque

Advantages:

• A decisive advantage of centrifugal brakes over conventional brakes is that they operate without an external power supply

Braking System

Manufacturer & Exporter of Braking System. Our product range also comprises of Permanent Magnet Generator, Emergency Overspeed Governor and Permanent Magnet Motor.

With whole new concepts, our company is dedicated towards manufacturing and supplying the most efficient Braking System. Considering miscellaneous necessities of our prominent clients, we offer these systems in a number of specifications to choose from. These systems are carefully designed by a team of very talented professionals. We make sure to offer this array to the clients at budget friendly prices. 

Features:

• Precision-designed
• No maintenance
• High performance

Product Details:

• Some environmental conditions, for instance hurricanes, include very high wind speeds. This may result in turbine runaway and destruction of the wind turbine. Additionally, it may be necessary to periodically stop the wind turbine spinning, if there is a mechanical or electrical fault or even during periodic maintenance. Thus some kind of braking system for the wind turbine is required
• Many turbines include a mechanical braking design (i.e. furling or tilting the axis of the turbine away from incoming wind). Alternatively, frictional beaks may be incorporated into the wind turbine. The disadvantage of such system is the short life expectancy and additional system cost and complexity of these systems
• Another option is to use electrical braking. Under high wind conditions heavy dump loads may be connected directly to the generator to slow the turbine enough causing the blades to "stall" aerodynamically. Once stalled, the torque produced by the turbine is greatly reduced, and it will spin at a very slow speed or stop
• The braking system design consists of a relay that connects the generator to a dump load when activated. In sufficiently strong winds the generator output will exceed a pre-set trigger level, i.e. breaking threshold. During operation the controller is continuously measuring the generator voltage (and thus speed) via the voltage divider. When the generator voltage exceeds the breaking threshold the breaking relay is activated, connecting a high power, low resistance dump load directly to the generator output. An anti-shock inductor has been placed in series with the dump load to avoid arcing at the contacts
• Stalling the wind turbine to avoid run-away is the primary purpose of the breaking system. However it can also be used to avoid the over charging the load (i.e. batteries) during high winds. If the controller senses that the batteries are being over charged, it will reduce the duty cycle, reducing the charging current. This will also unload the wind turbine and cause it to rotate faster. If the turbine is near the maximum speed a dump load can be added instead, slowing the turbine and reducing its power production. The presence of different dump loads is helpful in the reducing the turbine power by converting it to heat in the dump loads. Alternatively some useful intermittent loads, such as pumps, can be used instead of dump loads, only being activated at high wind speeds
• Breaking is initially overridden manually, and the generator is allowed to run over the breaking threshold limit. At approximately 7 seconds breaking is re-enabled, and the controller immediately goes into breaking mode, reducing the rotor speed to less than 30 rpm. At intervals of approximately 10 seconds the controller releases the breaks allowing the turbine to spin up until the threshold is again exceeded, and break is then reapplied. This continues until the wind speed is reduced below the breaking threshold, and normal operation ensues

Since our establishment, we have become the well-known manufacturer and supplier of a highly efficient Permanent Magnet Motor. In well-organized manner, these magnet motors are manufactured using better quality material that is sourced from the recognized vendors of the market. To ensure high performance and unmatched quality of this range, it is examined well against numerous quality parameters by our experts.

Features:

• Energy efficient
• Long service life
• Easy maintenance

Product Descriptions:

There was 185% PM brushless motor market growth between 2008 and 2011 in comparison with 29% overall motion control market growth in the same period of time.

The use of permanent magnets (PMs) in construction of electrical machines brings the following benefits:

• No electrical energy is absorbed by the field excitation system and thus
• There are no excitation losses which means substantial increase in efficiency
• Higher power density and/or torque density than when using electromagnetic excitation
• Better dynamic performance than motors with electromagnetic excitation (higher magnetic flux density in the air gap)
• Simplification of construction and maintenance
• Reduction of prices for some types of machines

In the last two decades new topologies of high torque density PM motors,high speed PM motors, integrated PM motor drives, and special PM motors have gained maturity. Cage induction motors have been the most popular electric motors in the 20th century. Recently, owing to the dynamic progress made in the field of power electronics and control technology, their application to electrical drives has increased. Their rated output power ranges from 70 W to 500 kW, with 75% of them running at 1500 rpm. The main advantages of cage induction motors are their simple construction, simple maintenance, no commutator or slip rings, low price and moderate reliability. The disadvantages are their small air gap, the possibility of cracking the rotor bars due to hot spots at plugging and reversal, and lower efficiency and power factor than synchronous motors.

The use of PM brushless motors has become a more attractive option than induction motors. Rare earth PMs can not only improve the motor's steady state performance but also the power density (output power-to-mass ratio), dynamic performance, and quality. The prices of rare earth magnets are also dropping, which is making these motors more popular. The improvements made in the field of semiconductor drives have meant that the control of brushless motors has become easier and cost effective, with the possibility of operating the motor over a large range of speeds while still maintaining good efficiency.

A PM brushless motor has the magnets mounted on the rotor and the armature winding mounted on the stator. Thus, the armature current is not transmitted through a commutator or slip rings and brushes. These are the major parts which require maintenance. A standard maintenance routine in 90% of motors relates to the sliding contact. In a d.c. commutator motor the power losses occur mainly in the rotor which limits the heat transfer and consequently the armature winding current density. In PM brushless motors the power losses are practically all in the stator where heat can be easily transferred through the ribbed frame or, in larger machines, water cooling systems can be used. Considerable improvements in dynamics of brushless PM motor drives can be achieved since the rotor has a lower inertia and there is a high air gap magnetic flux density and no-speed dependent current limitation.

Features:

• Precisely designed
• Flawlessly finished

Product Descriptions:

One of the greatest challenges associated with wind power is the unpredictable character of the wind. Even at the best wind sites, those with steady reasonably high speed wind, there are variations in speed and direction of the wind which affect the ability of the wind turbine to deliver power. Larger wind turbine systems have complex control systems which automatically track changes in wind direction and speed, and adjust turbine orientation, blade pitch, and generator gearing to maintain the desired electrical output. Small turbine systems are typically much less sophisticated, however they generally still have some form of control to improve their longevity and power production. 

The main purposes of a controller in a wind energy system are (in order of priority):

• Prevent damage to the load
• Maximum powermage to the wind turbine
• Prevent production

We will concern ourselves here with smaller wind turbine systems, which we will define somewhat arbitrarily as those systems rated at 20kW or less. Such small systems in the past have been predominantly designed for sturdiness, with robust mechanical controls, and relatively modest overall performance. With advances in microcontrollers, and electronic power switching components, however, the level of sophistication of theses small wind systems has been steadily improving.

PMG Advantage

Permanent Magnet Generator

Despite great efforts to improve the wind turbine gearbox designs, analysis, manufacturing, lubrication systems, control systems, etc., wind farm operators still suffer costly gearbox repairs and replacements multiple times in the life of their wind turbines.Wind turbine gearbox also needs regular oil change to ensure the turbine functions properly and effectively.

These PMG's don't require a gearbox since they are directly coupled to the turbine blades and are have been designed to produce a high power output at very low RPM.

Permanent Magnet Generators (PMGs), first introduced on a large scale to the wind industry in the early to mid-2000s, are expected to continue to increase market share from 17% in 2011 to nearly 40% by 2015. PMGs have a growing group of supporters because of the flexibility, improved reliability, and increased efficiency that they bring to drivetrain configurations.

About us :

We offer a selection of Low RPM Permanent Magnet generators in the range of 1 kilowatt to 100 kilowatts. Thinking about designing and building a small wind turbine? In order to match a generator to a turbine design, one would have to have an idea of the rpm range and the load. Building a prototype wind turbine can involve a lot of trial and error. The mantra is "build it, measure it". While we will do our best to assist, there are often so many unique and unknown variables, we can only guarantee what we know - which is the operating range of each generator ( please see  continuous vs.intermittent duty information for each generator). Our generators are a non-returnable item once connected to a power supply.
