Powder Dynamometers

Powder Dynamometers, as their name suggests, contain magnetic powder in Dynamometer. 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 – proportional to excitation.

The Powder Dynamometers produces their rated torque at zero speed.

The element to be tested can be loaded at standstill to determine the starting torque. Powder Dynamometer 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. Powder Dynamometers are ideal for applications operating in the low to mid speed range and mid to high torque range up to 3000 KgM (30000 Nm) of torque. For higher heat dissipation Powder dynamometers are provided with water circulation system for cooling, which passes inside the stator to dissipate heat generated by the braking power with power ratings up to 160 kW. They have system accuracy ratings of typically +/- 0.5% full scale, depending on Dynamometer size and system configuration By changing the exciting power force, the torque to be transmitted can be adjusted infinitely variable in the range 1:50. Powder dynamometers are typically limited to lower RPM due to heat dissipation issues

The mounting structure to accommodate the device under test, Torque & Speed transducer and Dynamometers is a sturdy mechanical structure designed for low vibrations. Safety guards for all the rotating elements are provided on the test bed with interlocks for safe operation.Test bed with T slot having X, Y & Z adjustment for Length, Width & Height adjustments is also offered along endurance test rig.

Advantage of Powder Dynamometer is that it controls Torque right from Zero RPM.

These are used to test Motors, BLDC Motors, PMSM Motors,PMAC Motors, Wiper Motors, Turbines, Gearboxes & Geared Motors, Low speed transmissions, Small Engines, Actuators etc.
