Ohming a 3 phase motor

Webb23 Motor-Lead Connections. 23. Motor-Lead Connections. Three-phase motors use coils of wire to create magnetic fields and produce rotation. Standard 3-phase motors use six individual coils, two for each phase. The internal construction and connection of these coils inside of the motor is predetermined when the motor is manufactured. Webb17 maj 2009 · That is pretty hard for 3-phase motors since it is essential in multi-speed multi windings applications that phase sequence is same. You need to discover what is number of windings, what is start and end of every winding and then how to connect it to contactors. That is why I asked for model make and manufacturer.
