A complete guide about solar panel installation.
Rev for three phase motor connection power and control diagrams.
A slip ring motor uses resistors in the rotor circuit to modify the starting characteristics of the slip ring motor.
As these motors have external resistance connected to its rotor circuit the value of starting current is adjusted or kept minimum by increasing the resistance of the rotor circuit.
It reduces the start current 2.
