Short Question on Switch Reluctance Motor

Explain the term : Torque ripple
Torque ripple

• It is defined as the difference between the maximum and minimum instantaneous torque during steady state condition. 
• It is expressed as percentage of the average torque.

Switch Reluctance Motor ( SRM ) Interview Question Answer - 1

What do you mean by term ‘Reluctance motor’?

Reluctance motor

• It is an electrical motor in which torque is produced due to position of rotor such that inductance of the excitation winding becomes maximum.

Describe the stator and rotor construction of the SRM.

• Stator : It is salient pole type and excited by field winding.
• Rotor : It is salient pole type.
