These motorsoperate through the use of magnetic fields. In simplestof terms, a motor is made up of coils (electromagnets)around the outside (known as the stator) and permanentmagnets mounted on the part of the motor that rotates(known as the rotor). The diagram below shows thesecomponents.To make the rotor rotate, 340 VDC is sent through a setof coils polarizing the electromagnet and causing thepermanent magnets on the rotor to rotate by eitherpulling towards or pushing away from theelectromagnets.Elecro-magnetArtisan Technology Group - Quality Instrumentation ...
