Sugawara Labs Hysteresis Brake Units for Motor Testing
HB Series hysteresis brake units for motor dynamometers and dedicated measuring jigs, providing current-controlled braking force regardless of rotation speed.
Hysteresis Brake Units for Motor Testing
Sugawara HB Series hysteresis brake units are designed for use in motor dynamometers, dedicated measuring jigs, and motor speed and torque measurement systems.
The brake unit applies a uniform braking force according to supplied electric current regardless of rotation speed. The mechanism is contactless and is designed to minimize inertial moment.Up to 30,000 r/minMaximum speed on listed brake-unit models
