Permanent Magnet DC Motors - sinotech

DC Permanent Magnet Motors. Maximum-energy product (MEP) is used to indicate the relative strength of permanent magnets used in the permanent magnet motors (PMDC). Samarium-cobalt magnets typically run from 18 to 26 MGOe while neodymium ranges from 8 to 35 MGOe. In comparison, the most widely used ferrite magnets only have an MEP of 1.8 to 4.5 ...

DC Motors - Motors - Grainger Industrial Supply

DC motors use permanent magnets or electromagnetic windings to convert electrical energy to mechanical energy that produces high starting torque and power. Torque combined with high voltage drives heavy loads when the motor is started. These motors use voltage to change speeds and can be used for precise speeds as well as positioning.

Permanent magnet DC (PMDC) motors | electricaleasy

Basic configuration of a permanent magnet DC motor is very similar to that of a normal DC motor. The working principle of any DC motor is same, i.e. when a current carrying conductor is placed in a magnetic field, it experiences a force. A permanent magnet DC motor also works on the same principle.
