Construction of DC Machine (Generator & Motor)

The dc generators and dc motors have the same general construction. In fact, when the machine is being assembled, the workmen usually do not know whether it is a dc generator or motor. The m.m.f. developed by the field coils produces a magnetic flux that passes through the pole pieces, the air gap, the armature, and the frame.

Permanent Magnet Synchronous Motor (PMSM) cypress

Permanent Magnet Synchronous Motors (PMSM) are similar to Brushless DC motors (BLDC). PMSM are rotating electrical machines that have a wound stator and permanent magnet rotors that provide sinusoidal flux distribution in the air gap, making the BEMF inform a sinusoidal shape. The construction of the stator and rotor can provide lower rotor inertia and high power efficiency

AC Induction Motors vs. Permanent Magnet Synchronous

A "PMSM", which stands for "permanent magnet synchronous motor", relies on magnets to turn the rotor, which spins at the same speed as the PMSM''s internal rotating magnetic field. There are a few key differences between AC induction Motors and Permanent Magnet Synchronous Motors. Permanent magnet motors MUST operate with a drive.

Electric motor Construction of induction motors

Electric motor Construction of induction motors: 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.
