Product Description

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% to ± 0.5% 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% to ± 0.5% (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

Specifications and Drawings

Note: Operating at the continuous power rating for periods of up to 4 hours is acceptable. However, operating for extended periods at high temperatures will result in premature component and bearing failure. Limiting the length of the cycle and the component temperatures will guard against premature failure. Where continuous duty is desired for longer time intervals, component temperatures should be maintained less than 100°C; monitoring the outside brake surface temperature is a sufficient reference.

• Model HD-510, HD-515, HD-800 and HD-805 Dynamometers require air cooling provided by user. Regulator and filter package is provided as standard equipment on these units. See data sheet for pressure ratings.

• Blower package is included as standard equipment with Model HD-710, HD-715, HD-810, HD-815 and HD-825 Dynamometers.

• All -5N(A) dynamometers are 5 Volt Output

Blower Dimensions

Allow approximately 6 in to 8 in (152 mm to 203 mm) between rear

of dynamometer base plate and blower for connection hardware.

Required hardware is supplied with the dynamometer.

Blower Power and Fuses

• Models HD-710, HD‑715, HD-810 and ED-715 include the BL‑001 blower.

• Models HD‑815 and ED-815 include the BL‑002 blower.

• Model HD‑825 uses two BL‑002 blowers for cooling its two brake sets.
