Description
DC permanent magnet motors have a torque-speed charac-
teristic with shunt characteristics. Thanks to a particular
dimensioning of the armature winding (copper filling fac-
tor) there is only a low speed reduction under load.
The magnetic flux necessary to generate the torque is pro-
duced by permanent magnets.
A special field excitation winding and thus an element that
would cause additional heat loss is not required. This
means that the efficiency of a DC permanent magnet
motor is better than the efficiency of a comparable field-
wound DC motor. As permanent magnets are smaller than
a comparable field winding, a DC permanent magnet
motor is approximately one frame size smaller than a field-
wound DC motor with the same rated power.
