The PMG 132 is a multi-pole, permanently excited DC motor with brushes. Its compact design requires for less installation space while providing strong torque of up to 38 Nm.
The PMG 132 is a multi-pole, permanently excited DC disc motor. The Excitation field is created using high performance permanent magnets from rare earth. The disc shaped rotor has been made with copper profilled lamella at whose inner end a disc commutatır is moulded by means of suitable profiling. Power is transmitted via metalliferous carbon brushes which are optimally adapted to the shape of the commutator and conducted via a special brush holder alignment.
The magnetic flow passes axially through the laminatin stacks This alignament reduces the air gap to the minimum required mechanically and reduces magnetic losses. What results is far greater efficiency (approx 90%) across a broad range of operating conditions.
