Permanent magnet dc motor


Permanent magnet dc motor

Rotating magnetic field as a sum of magnetic vectors from 3 phase coils.

An electric motor converts electrical energy into kinetic energy. The reverse task, that of converting kinetic energy into electrical energy, is accomplished by a generator or dynamo. In many cases the two devices differ only in their application and minor construction details, and some applications use a single device to fill both roles. Permanent Magnet Redline DC Motor Product Specifications. For example, traction motors used on locomotives often perform both tasks if the locomotive is equipped with dynamic brakes.


Most electric motors work by electromagnetism, but motors based on other electromechanical phenomena, such as electrostatic forces and the piezoelectric effect, also exist. The fundamental principle upon which electromagnetic motors are based is that there is a mechanical force on any current-carrying wire contained within a magnetic field.
