Xc 2485 Wiring Diagram For Motor Starter 3 Phase Schematic
Dol wiring diagram single phase. The direct on line motor starter dol is designed to switch a single or three phase induction motor at rated voltage. Ladder diagram basics 3 2 wire 3 wire motor. What is dol starter. When the motor hits a certain speed a switch inside the motor disconnects the start winding. 1 22kw motor with a flc of 5 amps at 415volts. The connection of the supply to the motor is normally on the underside of the motor terminal lid loldoesnt matter which way.
The run winding and the start winding the start winding is normally connected to the supply and a capacitor. In the above one phase motor wiring i first connect a 2 pole circuit breaker and after that i connect the supply to motor starter and then i do cont actor coil wiring with normally close push button switch and normally open push button switch and in last i do connection between capacitor start motor and contactor.
