The d.c. permanent magnet (PM) motor is a continuous-rotation electromagnetic actuator which can be directly coupled to its load. Figure 2.56 shows the schematic representation of a d.c. PM motor. The PM motor consists of an annular brush ring assembly, a permanent magnet stator ring and a laminated wound rotor.
BASICS OF MOTORS AND MOTOR CONTROL When the magnetic field of the magnets are put in the picture, the two magnetic fields distort. A turning force, or torque, acts on the coil. The lines of force act like stretched rubber bands that tend to contract. The result is that the armature rotates in a counterclockwise direction.
