Linear Induction Motor

A Linear Induction Motor (LIM) is an advanced version of rotary induction motor which gives a linear translational motion instead of the rotational motion. The stator is cut axially and spread out flat. In this type of motor, the stator and rotor are called primary and secondary respectively. The secondary of the linear induction motor…

Two Phase AC Servo Motor

As we have already seen What is a Servo Motor? In the previous article. Here I am going to discuss the Two Phase and Three Phase AC Servo motor. The stator of the Two Phase AC Servo Motor has the two distributed windings which are displaced from each other by 90 degrees electrical. One winding…

Printed Circuit Board (PCB) Motor

A Printed Circuit Board or a Disc Armature motor consists of a rotor disc made of non-magnetic and non-conducting material. The armature winding and the commutator are printed with copper on both the sides of the disc. The disc armature is placed between two sets of permanent magnets mounted on the ferromagnetic plates. Brushes are…

Servo Motor

Servo Motor 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…

Universal Motor

The motors which can be used with a single phase AC source as well as a DC source of supply and voltages are called as 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…

Detent Torque

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. It exists because of the residual magnetism in the…

Stepper Motor Applications

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 about What is a Stepper Motor? and the Step Angle. The Stepper Motor Applications have a…

Stepper Motor

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…

Hysteresis Motor

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:…

Reluctance Motor

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 are same. The rotor of a reluctance motor is a squirrel cage with some rotor teeth removed…
