Capacitor Split in Single Phase Induction Motors — Lesson 5

This lesson covers the concept of starting torque in single phase induction motors with an oval ad binding. It explains how the starting torque is equal to the synchronous watt and how it can be maximized by selecting an optimum value of external auxiliary winding resistance. The lesson also discusses the use of resistor split motors and capacitor split phase motors, explaining how to calculate the optimum value of the capacitor for starting. The lesson further delves into the concept of phase splitting and the importance of constructing a phasor diagram to ensure maximum starting torque.
