Dynamometers measure torque regardess of shaft speed.

Press Release Summary:



Model HD, with hysteresis braking system, does not require speed to create torque, and can provide full motor ramp from free-run to locked rotor. Brake cooling is provided by convection, compressed air, or dedicated blower. It is suitable for testing in low to medium power ranges up to 14kW intermittent duty. Accuracy is 0.25% to 0.5% full-scale. It has standard English, metric, and SI torque measurements and optional encoder switch.

Magtrol's Hysteresis Dynamometers Provide Precise Torque Loading Independent of Shaft Speed


Buffalo, NY - Magtrol's Hysteresis (HD) Brake Dynamometers are versatile and ideal for testing in low to medium power ranges (max. 14kW intermittent duty). With a hysteresis braking system, the dynamometers do not require speed to create torque, and therefore can provide a full motor ramp from free-run to locked rotor. Brake cooling is provided by convection (no external source), compressed air or dedicated blower, depending on the model. Other features of the HD dynamometer include ±0.25% to ±0.5% full-scale accuracy ratings; high repeatability; ease of operation; standard English, metric and SI torque measurement options; easy calibration and an optional encoder switch.

Magtrol's HD Dynamometers are used in a wide array of industries including Appliance, Automotive, Aviation, Computer, HVAC, Lawn and Garden, Medical, Dental, Electric Motor, Office Equipment and Power Tools. They can be used for manual testing or easily converted into a PC-based system when combined with Magtrol's DSP6001 High Speed Programmable Controller and M-TEST 4.0 Software. Custom designs are available for special torque and speed requirements.
