DC shunt motor is a DC motor equipped with shunt winding and series winding in the main magnetic pole.
Compound machine excitation winding is divided into two parts, part of the series with the armature winding, the other part with the armature winding in parallel, according to the direction of the magnetic field can be divided into two parts winding generation compound machine and compound machine. Compound DC motor is widely used in ships, trolley buses and lifting mining equipment.

Ltekonline are the manufacturers of DC Compound Machine used to demonstrate engineering principles in Engineering Colleges, Engineering Schools and Electrical Machine Trainer for Engineering Teaching Lab in Universities
