Hysteresis dynamometer
Hysteresis dynamometer
Composition and principle:
Hysteresis dynamometer toothed pole stator composed of hollow hysteresis Cup rotor excitation coils, stents, floor, when hysteresis dynamometer internal coil through the current generated magnetic field lines, and form a magnetic circuit and produce torque, Changing the excitation current to change the load torque.
Applicable occasions
Higher for small and medium torque and speed motor testing, such as the starter motor constant torque starting with load, asynchronous motor, low-power DC motor, series motor and electric tools, especially suitable for testing a variety of motor dynamic characteristic curve.
