By BYJU'S Exam Prep
Updated on: September 25th, 2023
(A) Capacitor start induction motor
(B) Capacitor-run induction motor
(C) Split phase synchronous motor
(D) Shaded pole motor
Capacitor start induction motor will give relatively high starting torque. A single-phase induction motor with a capacitor-start uses a capacitor in the circuit for the auxiliary winding to increase the phase difference between the current flowing through the main and auxiliary windings.
How Does Capacitor Start Induction Motor give High Starting Torque?
The capacitor starts the motor and generates a beginning torque between three and four times that of the full load torque. The order of starting torque in the increasing order is:
Shaded-pole motor < Split phase motor < Capacitor start capacitor run motor < Capacitor start motor
Summary:
Which of the following motor will give relatively high starting torque? (A) Capacitor start induction motor (B) Capacitor run induction motor (C) Split phase synchronous motor (D) Shaded pole motor
The Capacitor Start Induction Motor will give relatively high starting torque. The capacitor helps to start the motor and generate torque in the beginning phase.
