Magnetic Particle Brakes & Clutches are popularly known as Powder brakes & clutches. These powder brakes & clutches are manufactured by us in wide range from tiny 0.3 KgM to massive 100 KgM torque range

These are manufactured in self cooled, forced air cooled & water cooled version. Powder brakes & clutches are real torque control device, meaning braking or clutching torque is strictly proportional to excitation current,

The magnetic powder clutch and brake achieves at low control power a high torque being independent from the slip speed. It distinguishes itself by a simple construction, low weight and small required space. Due to this advantage the clutch / brake is used for the solution of many technical problems. For the various applications also appropriate control devices are necessary. By changing the exciting power force, the torque to be transmitted can be adjusted infinitely variable in the range 1:30

The Powder Brakes & Clutches contain, as their name suggests, a magnetic powder. The electrical current passing through the coil generates a magnetic field, which changes the property of the powder, from free flowing condition at no excitation to solid rock condition at full excitation. Thus producing a smooth braking torque through friction between rotor and stator. The Powder Brakes & Clutches produces their rated torque at zero speed. The element to be tested / Clutched, can be loaded at standstill to determine the starting torque.

8. TACHOGENERATOR

TACHOGENERATOR
Tachogenerator is a device which generates an electrical output directly proportional to the shaft speed. The voltage thus generated is fed to a speedometer for speed measurement and/or used as feed - back signal for controlling the speed of a rotating machine / equipment. In every automatic control system, since the system performance is directly related to the performance it becomes essential that the Tachogenerator must satisfy certain minimum requirements such as:
Linear
The rectified output voltage should be strictly linear with respect to the rotational speed
Output signal
the ripple content in the rectified output signal must be as low as possible
Temperature effect
Variations in ambient temperature should have negligible effect on the TG output
Long-term stability
Instability of output cause due to aging of parts, shift in magnetic circuits etc., should be minimum

Unique features of Tachogenerator
ALINCO permanent magnet in the rotor assembly gives long term stable operation under varying ambient temperature.
Large number of poles (48) results in a high frequency output and hence good dynamic response,
   linearity and wide speed control, along with low ripple content in the rectified output.
Rotor and stator assemblies are encapsulated with epoxy resin to prevent any ingress of moistures, dust etc.
AC tachogenerators in 24 or 48 pole constructions with quasi-sinusoidal output of 30/ 50 Volts AC (rms) @ 1500 rpm
Stator assembly is housed in cast iron body to minimize magnetic interaction and consequent losses.
