Hysteresis Brake Dynamometers (HD-100, 400 & 500 Series) are versatile and ideal for testing in the low power range (maximum 800 watts 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) or by compressed air, depending on the model. All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% to ± 0.5% full scale depending on size and system configuration. T

o better integrate dynamometers into systems, Magtrol now offers both long and short base plates. The shorter base plate facilitates easier motor mounting when used with T-slot tables and Magtrol Adjustable Motor Fixtures, where as the long base plates are better suited for table top testing.
