Our brushed motors are the start of Plettenbergs journey to become a leading manufacturer of electric motors. As compared to permanent magnet brushed DC motors, shunt wound brushed DC motors have no loss of magnetism and are more robust. Shunt-wound brushed DC motors are typically used in applications that require 5 or more HP such as industrial and automotive applications. Lets consider two real world examples, looking at motors in Portescaps Athlonix series of brushed DC motors. Rotating the motor shaft moves the winding segment through the sinusoidal varying magnetic flux in the air gap. However, a brushed DC motor does not need any conversion. Answer (1 of 41): It might come as a surprise to some readers, but there is absolutely no need for any conversion, for while many DC motors are operating as motors, THEY ARE AT THE VERY SAME TIME ACTING AS GENERATORS while their conductors in This is a very simple model as there are only two wires for the output and it does not matter which direction the generator spins. Against this background, the ability of a brushed DC motor to act as a generator and provide a DC supply can be very useful indeed. The main body of the motor is the stator, consisting of the permanent magnet which is centrally located around the shaft, within the housing and the mounting flange. With the shaft mechanically coupled to and rotated by an external source, causing the coil segments in the rotor to rotate through a magnetic flux in the air gap, a back EMF is measured at the output terminals. 2100 series.
