It is then obvious that the increase in the angle (from 30 degrees to 80 degrees) alone increases the starting torque to nearly twice the value developed by a standard split-phase induction motor. The torque developed by a split-phase induction motor is directly proportional to the sine of the angle between Is and Im. One often-used method is the Split Phase motors. The starting, speed/torque characteristics of each of the above motors can be analyzed before employing them in work. It is evident from the phasor diagram that the current through the starter winding Is leads the voltage V by a small angle and the current through the main winding Im lags the applied voltage. (click on an image to enlarge it). But the current through the main winding Im, still lags the applied voltage V across the circuit.

These motors can be used for various purposes depending upon the need of the user. All rights reserved..


Also the angle is 30 degrees in case of split-phase motors. Another method is the Capacitor Start Induction Run Motors. Theraja. Read on to learn about the different types of widely used capacitor-motors slide 1 of 4 The single-phase induction motor can be made to be self-starting in numerous ways. slide 2 of 4 Capacitor-Start Induction-Run Motors We know about the activity of a capacitor in a pure A.C. When the motor reaches about 75% of the full load speed, the centrifugal switch S opens and thus disconnecting the starter winding and the capacitor from the main winding. slide 3 of 4 Types of Motors There are different types of Capacitor-start motors designed and used in various fields. Thus a capacitor-start induction-run motor produces a better rotating magnetic field than the split-phase motors.
