In most common DC motors, the magnetic field is produced by highstrength permanent magnets, which have replaced traditional field coil
windings. The magnets require no current from the power supply. This improves motor efficiency and reduces internal heating. In addition, the
reduced current draw enhances the life of batteries used as power supplies in mobile or remote applications.

 

Both AC and DC motors must be manufactured with a great deal of precision in order to operate properly. LEESON and other major manufacturers use laminated stator, rotor and armature cores to reduce energy losses and heat in the motor. Rotors for AC motors are heat treated to separate the aluminum bars from the rotor’s magnetic laminations. Shaft and bearing tolerances must be held to ten thousandths of an inch. The whole structure of the motor must be rigid to reduce vibration and noise. The stator insulation and coil winding must be done in a precise manner to avoid damaging the wire insulation or ground insulation. And mountings musts meet exacting dimensions. This is especially true for motors with NEMA C face mountings, which are used for direct coupling to speed reducers, pumps and other devices.

 

 

The electric motor is, of course, the very heart of any machine it drives. If the motor does not run, the machine or device will not function. The
importance and scope of the electric motor in modern life is attested to by the fact that electric motors, numbering countless millions in total, convert more energy than do all our passenger automobiles. Electric motors are much more efficient in energy conversion than automobiles, but they are such a large factor in the total energy picture that renewed interest is being shown in motor performance. Today’s industrial motors have energy conversion efficiency exceeding 95% in larger horsepowers
