Switched Reluctance Motor Question & Answers January 12, 2023 By Wat Electrical This article lists 50 Switched Reluctance Motor MCQs for engineering students. All the Switched Reluctance Motor Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on the fundamentals of Switched Reluctance Motor. An electric motor operates on a combination of electric and mechanical energy to convert one form of energy to another on its mechanical force and speed. They are classified into multiple types based on their parametric measuring. A motor that passes non-permanent type magnetic poles onto Ferro-type magnetic rotor is a reluctance motor. The types of reluctance motors include synchronous and switched-type motors. A switch-type reluctance motor operates on the dynamic reluctance-type torque principle. Rotor, stator, shaft, and coil are the main components of this motor. Where the rotor adjusts itself towards the minimum reactance lane according to its working principle. Linear SRM/ servos SRM which has a uni step stator and Rotary SRM are the 2 types of SRM. A rotary SRM is further classified as axial and radial field SRM. They benefit in terms of good performance, greater efficiency, and enhance reliability. They lag in terms of includes low torque, and greater ripples in torque at high speed. They are deployed in Coil windings, rolling-type machines, and electric-type vehicles. 1). Which of the following are components of reluctance motor?
