Which of the following is NOT a valid advantage of hybrid stepper motors? Correct Answer Low inertia and weight

Hybrid stepper motor:

  • The combination of two motors like a permanent magnet and variable reluctance is known as a hybrid motor.
  • The working principle of a hybrid motor is, that the rotor in this motor is magnetized axially similar to a permanent magnet stepper motor, whereas the stator is energized electromagnetically similar to a variable reluctance stepper motor.
  • So it is an actuator that changes electrical pulses to angular displacement.

Advantages of hybrid stepper motor:

  • The length of the step is smaller.
  • It has greater torque.
  • Higher efficiency at a lower speed.
  • It provides detent Torque with the de-energized windings.

Disadvantages of hybrid stepper motor:

  • These motors have high inertia.
  • This motor weight is high due to the rotor magnet within the motor.
  • The motor performance will be affected due to magnetic strength.
