In most high volume EV applications motor laminations are made from silicon steel says the alloys company. However in EVs higher up the performance scale and in heavy duty commercial vehicles where the application requires greater torque and power density high induction and low loss iron cobalt alloys come to the fore.
Typically the rotor is placed in the middle part of the engine and rotates when the poles are attracted and the stator poles repel. Stator. Stator’s electromagnet’s wire length is the key to the strength of your industrial motor. Figure 3 Stator and Rotor. The stator is the central part of the electromagnetic circuit.

PMMs used in UHS service of a major manufacturer 43 have six poles and a rated speed of 10 000 RPM at a frequency of 500 Hz. Their rotors are considerably shorter than those of standard IMs and thus have a much higher power density. The heat generated by the motor s operation at such high speeds required the development of an enhanced cooling system.

An induction motor. Energy efficiency and load
Dec 24 2018 As stated elsewhere the stator pole faces if desired may be reduced to 25 of the rotor pole face area hence large drive windings and high drive current is not required. With care to detail correct mathematical calculations and high quality instrumentation correctly utilised incredible results can be expected.
Jul 14 2009 It is a huge waste of time and money to replace the bearings and most shops will tell you this.The better way is get a high quality reman alternator instead saving time. A shop will tell you that because they can t rebuild the unit in shop for the price of a reman and they don t want to chance a comeback.

The stator frame consists of laminations of silicon steel usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer. This breaks up the conducting path in the steel and limits the losses known as
