Question about Baldor 1/2 Hp Motor M3538 1725 Rpm 5/8" Shaft 230 V
Have a burnt 3 phase motor that nameplate is RPM 3450 230/460V PH 3 AC Motor And want to replace it into RPM 2800/3500 200-230/380-415v ph 3 Multistage Turbo Blower I wander what rpm would be of the to be replaced motor that sticker marking is 380v 50Hz if i connect it into 220v or 230v? What would be the advantage or disadvantage of using a motor that 380 volt connected into 220v or 230v. I tried to connect it at 230volt and it runs good. Thanks in advance.
The higher the voltage the lower the amperage, so advantage is its more cost effective to run it at highe voltages since power consumption is I squared x Resistance. The resistance will be the same but the lower the current the less it cost to run it.

Thank you for posting your question here on Fixya.com.
I am not sure what you mean by "center wire". For 230V single phase you should have 2 hot line leads (115V each) and a ground wire. Set the motor leads as the nameplate shows for the high voltage connection and attach your line leads where the two lines are indicated. If you have a 3+Grd wire drop DO NOT connect the neutral, insulate it and leave it unconnected. It will not matter which line lead connects to which motor line wire as far as rotation direction. To change rotation, if the motor allows it, you reverse the start winding leads as directed on your nameplate.
