Single Phase 120 240 Volt Motor Wiring Diagram

In north america many single phase motors motors in the range of 1 hp to 2 hp can be rewired to run at either 120 volts or 240 volts or 115 vs 230 volts it depends on what voltage is assumed nominal. Rewiring a motor from 240 volts to 120 volts.

240 Volt Motor Wiring Schematic Auto Electrical Wiring Diagram

For 240 volts connect one start winding wire to the junction of t3 and t2 the start winding is always operated on 120 volts even if the motor is 120240 volts and the other wire to a remaining drum switch terminal.

Single phase 120 240 volt motor wiring diagram. Single phase 220 volt ac motors are really two phase 240 volt motors especially when compared to three phase 208 volt motors and single phase 120 volt motors. As explained above in a utility connected 120 240 vac single split phase system the 120 240 vac power consists of two 120 vac lines viz. It reveals the components of the circuit as simplified shapes as well as the power and also signal connections in between the tools.

Such motors will typically have six leads coming out of the motor to the wiring box or some of the connections may be screw terminals. For 120 volts connect the start winding wires to the remaining drum switch terminals. Single phase motors are used to power everything from fans to shop tools to air conditioners.
