Only very small motors don't need capacitors. Some motors have them sort of built in mounted on the side. Look on the cover plate where the wires tie onto the motor. There should be directions on changing voltage settings. If not there, look around the terminals themselves. Still no help, get the make and model of the motor and search the internet. The manufacturer will be able to help. If you need a capacitor and don't use one, the motor will just hum, get hot, and quit. Lastly, be careful jumping wires around not knowing where you place them. You might have already burn up that motor. Never forget. Electricity can kill. That electrician might seem expensive but you will be alive when you are done.

there are 2 rows off 3 connectionpoints the 3 wires are connected to the last row ,there isn't a setup on the cover off the motor the motor is i think more then 25 years old. i also have seen the same 2 rows 3 connections on another motor (i try that on 380 volt but it's to mutch work to lay another cable on 380 volt again from the powerbox) i believe thise motor already runned at 230 volt so i believe these setup in the motor box is set ok . hope u know more .

You need a pair of capacitors to link the other two phases that are not directly connected. Please consult a qualified electrician before you cause harm!

the motor have been connected to a outlet with 230 volt butt that setup wasn't there when i take off the motor . it runned at 230 volt. butt i don't know how it got connected. so i believe there isn't a capacitor needed to let the motor run.
