air-cooled brakes

When torque control/torque measurement must be performed at the highest possible power, Magtrol AHB Series Hysteresis Brakes are ideal. Passages running through the brakes enables compressed air cooling, providing excellent heat dissipation. This design allows for continuous power ratings up to 3000 watts (5300 watts intermittent). Use of pre-loaded bearings in the AHB Series Hysteresis Brakes allows operation at speeds of up to 25,000 rpm for extended durations.

AHB Brakes are conveniently base mounted. Base mounting, with integral barrier type terminal strip, provides easy mounting and wiring.

Magtrol’s AHB Series Compressed-air-cooled Hysteresis Brakes can function in either torque measurement or torque control applications. When mounted to the PT 25 Series T-slot Base Plate, a cost-effective, basic motor test rig can be easily configured. For this purpose, Magtrol offers several accessories and system options to choose from. The simplest test bench may include one or two AHB Brakes and an AMF Adjustable Motor Fixture mounted onto a PT Base Plate. Adding a TM Series In-Line Torque Transducer, couplings, FR10 Free-Run Speed Sensor, 3410 Torque Display or DSP6001 Controller greatly expands the system’s motor testing capabilities.

Other accessories available from Magtrol include: power supplies, air filters, pressure gauge kits, air lines, pipe fittings, jack shafts and risers.

In addition to motor test applications, AHB Series Compressed-air-cooled Hysteresis Brakes can be used for the following:

• Durability/reliability verification
