What frequency range can hysteresis motors operate within?

Hysteresis motors are capable of operating effectively within a frequency range of 25 to 2000 Hz. This broad frequency range is attributed to the design of hysteresis motors, which utilize a synchronous principle for operation. The rotor in a hysteresis motor is made of a material that exhibits hysteresis losses, allowing it to synchronize with the rotating magnetic field produced by the stator windings across various frequencies.

The ability to function well over a wide spectrum of frequencies enables hysteresis motors to be versatile in various applications, especially in situations where precise speed control is important. This flexibility in frequency allows these motors to be used in different industrial settings, where fluctuations in supply frequency may occur.

Other provided ranges do not fully encompass the operational capabilities of hysteresis motors, as they either fall short of the lower limit or do not extend to the upper limit that hysteresis motors can address effectively. This makes the chosen frequency range the most appropriate and accurate representation of the operating capabilities of hysteresis motors.
