Dynamometer brake HD series

hysteresiselectromagneticmechanical

Hysteresis Brake Dynamometers (HD Series) are versatile and ideal for testing in the low to medium power range (maximum 14 kW 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), by compressed air or by dedicated blower, depending on the model. All Magtrol Hysteresis Dynamometers have accuracy ratings of ± 0.25% full scale — depending on size and system configuration. To better integrate dynamometers into systems, Magtrol 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. Features 16 Standard Models with Maximum Torque from 2.5 oz·in to 500 lb·in (18 mN·m to 56.5 N·m) Hysteresis Braking System: Provides precise torque loading independent of shaft speed Motor Testing from No Load to Locked Rotor Accuracy: ±0.25% (Full Scale) Air Flow Sensor: For protection against overheating and operator error Standard Torque Units: English, Metric and SI Base Plate: Available in long or short versions Custom Dynamometers: for special torque and speed requirements Easy Calibration
