Types of DC Motors: Series, Shunt, Compound, Permanent [PDF]

WebA type of DC motor which consists of both series field winding and shunt field winding to produce the required magnetic flux in the machine is called a compound DC motor. Depending on the series and shunt field winding arrangement in the motor circuit, the compound DC motors are further classified into the following two types. WebAns: In Brush Less DC Motors, the armeture (coil winding to form poles) is put on stator and rotor is made using Permanent Magnets. When the armeture of the stator is passed through DC current , the Magnetic field is generated. However when fixed DC current is applied this will generate a constant magnetic field and rotor can not run with this.
