Servo motors are also called Control motors. They are used in feedback control systems as output actuators and does not use for continuous energy conversion. The principle of the Servomotor is similar to that of the other electromagnetic motor, but the construction and the operation are different. Their power rating varies from a fraction of …
The motors which can be used with a single-phase AC source, as well as a DC source of supply and voltages, are called Universal Motor. It is also known as Single Phase Series Motor. A universal motor is a commutation-type motor. If the polarity of the line terminals of a DC series motor is reversed, …
Definition: Detent Torque is defined as the torque at the maximum load that is applied to the shaft of the motor which is unexcited without causing continuous rotation. It is also known as Restraining Torque and is produced in the rotor of the permanent magnet motor. The detent torque exists because of the residual magnetism …
The Stepper motor is manufactured in various sizes ranging from milliwatts to hundreds of watts. Its maximum torque value ranges up to 15 Newton Meter and the step angle ranges from 1.8 to 90 degrees. As already discussed earlier What is a Stepper Motor? and the Step Angle. The Stepper Motor Applications have a wide …
The name Stepper Motor itself shows that the rotor movement is in the form of various steps or discrete steps. It is also known as Stepping Motor. The number of pulses fed into the controller circuit determines the angular rotation of the motor. Each input pulse produces one step of the angular movement. The drive …
A Hysteresis Motor is a synchronous motor with a uniform air gap and without DC excitation. It operates both in single and three-phase supply. The torque in a Hysteresis Motor is produced due to hysteresis and eddy current induced in the rotor by the action of the rotating flux of the stator windings. Contents: Construction …
A single-phase synchronous Reluctance Motor is basically the same as the single cage type induction motor. The stator of the motor has the main and auxiliary winding. The stator of the single-phase reluctance and induction motor is the same. The rotor of a reluctance motor is a squirrel cage with some rotor teeth removed in …
The Single Phase and Three Phase Induction Motor is differentiated on the various factors in this article such as the supply on which they operate, their starting torque, maintenance, features, the efficiency of the motor, their power factors, and the example where the two motors are used. The difference Between Single Phase and Three Phase …

Definition: The shaded pole induction motor is simply a self-starting single-phase induction motor whose one of the poles is shaded by the copper ring. The copper ring is also called the shaded ring. This copper ring acts as a secondary winding for the motor. The shaded pole motor rotates only in one particular direction, and …
The equivalent circuit of a Single Phase Induction Motor can be obtained by two methods named the Double Revolving Field Theory and Cross Field Theory. Firstly the equivalent circuit is developed on the basis of double revolving field theory when only its main winding is energized. Considering the case when the rotor is stationary and …
