This means, in a total revolution cycle the rotor will go stepwise eighteen times, every time 10 degree. However, in a stepper motor, the complete revolution angle can be separated in numerous steps like 10 degree X 18 steps. We know that for any rotor, the whole revolution angle is 180degrees. The stepper motor can be used to offer step angle revolution, as an alternative to stable revolution. The special purpose motors mainly include servo motor, stepper motor, linear induction motor, etc. Please refer to this link to know more about induction motor types and advantages Based on the rotor construction, these motors are classified into two types namely squirrel cage & phase wound. Induction motor mainly uses electromagnetic induction for changing the energy from electric to mechanical. The electric motor which runs asynchronous speed is known as induction motor, and an alternate name of this motor is the asynchronous motor. Please refer to this link to know more about synchronous motor types and applications. When the rotation accuracy level is high, then these motors are applicable in automation, robotics, etc. There is no air gap among the speed of stator current and rotor. As well as the rotor depends on the similar speed of the stator current. The stator in the electric motor generates the field current which rotates in a stable speed based on the AC frequency. The working of the synchronous motor mainly depends on the 3-phase supply. The types of ac motors mainly include synchronous, asynchronous, induction motor. The shunt winding can be designed with multiple windings of copper wire to get the full i/p voltage. The series winding can be designed with few windings of wide copper wires, which gives a small resistance path. In this type of electric motor, the stator and rotor can be connected to each other through a series & shunt windings compound.

In this type of motor, both the fields like series and shunt are present. Generally, DC compound motor is a hybrid component of DC series and shunt motors. Please refer to this link to know more about P MDC Motor: Construction, Working, and Applications 5). It is one kind of DC motor which can be inbuilt with a permanent magnet to make the magnetic field necessary for the electric motor operation. The term PMDC stands for “Permanent Magnet DC motor”.
