From this Article:
A linear dc motor, like a rotating dc motor, generates mechanical force by the interaction of current in conductors and magnetic flux provided by permanent neodymium magnets. It is constructed of a... (View Full Article)

From this Article:
Definite-purpose motors handle specific applications and have well-established NEMA standards. They are produced in high volume, and are low in cost when compared to general-purpose motors with the... (View Full Article)

From this Article:
These motors are probably the simplest and most rugged of all electric motors. They consist of two basic electrical assemblies: the wound stator and the rotor assembly. The rotor consists of... (View Full Article)

From this Article:
A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180�. But they are widely used to operate... (View Full Article)

From this Article:
Motors should have protection for themselves, the branch circuit, and the feeder line. Other protection, provided by fuses and circuit breakers, guards against fault conditions caused by short... (View Full Article)

From this Article:
Single-speed squirrel-cage motors have starters that fall into two categories: full-voltage or across-the-line starters; and reduced-voltage starters. Full-voltage starters (manual and magnetic) apply... (View Full Article)

From this Article:
Industrial applications use dc motors because the speed-torque relationship can be varied to almost any useful form -- for both dc motor and regeneration applications in either direction of rotation.... (View Full Article)

From this Article:
Without complex electronic control, synchronous motors are inherently constant-speed motors. They operate in absolute synchronism with line frequency. As with squirrel-cage induction motors, speed is... (View Full Article)
