[post_content] => 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.
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
- Custom Dynamometers: for special torque and speed requirements
- Easy Calibration
The Hysteresis Braking System
All Magtrol Hysteresis Dynamometers absorb power with a unique Hysteresis Braking System which provides frictionless torque loading independent of shaft speed. The Hysteresis Brake provides torque by the use of two basic components - a reticulated pole structure and a specialty steel rotor/shaft assembly - fitted together but not in physical contact. Until the pole structure is energized, the drag cup can spin freely on its shaft bearings. When a magnetizing force from the field coil is applied to the pole structure, the air gap becomes a flux field and the rotor is magnetically restrained, providing a braking action between the pole structure and rotor.

PT Series T-slot Base Plates are used for creating a basic test rig by mounting a Magtrol Dynamometer,
Brake or
Torque Transducer in line with the unit to be tested. Depending on the system configuration, a riser may be required to lift the transducer from the baseplate to the shaft height of the brake and/or the motor being tested. Magtrol RTM Riser Kits come complete with attachment hardware for the transducer and T‑nuts and bolts for attachment to the PT Base Plate.

[post_content] => Finally… a Micro Dyne system designed specifically for your micro motors!
With over 50 years’ experience in dynamometer design and torque measurement, Magtrol has revolutionized the industry. Magtrol’s
new Micro Dyne, capable of measuring extremely low torques (2.0 mN·m can be resolved to 0.0004 mN·m), is
designed exclusively for testing miniature and micro motors.
For the utmost convenience, the Micro Dyne is packaged as a
complete motor testing system. Everything that is needed to accurately and efficiently test miniature motors and micro motors is included with the purchase of a Magtrol Micro Dyne. The only component that needs to be supplied by the customer is a laptop or desktop personal computer and a motor power supply.
