An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. The rotor of an induction motor can be a squirrel cage rotor or wound ...
A step motor or stepping motor is called a stepper motor in which the single rotation is divided into a number of steps. Each step is being calculated by an angle. The step angle can be varied as per the design of the motor. It has a permanent magnetic rotating shaft called the rotor and stationary electromagnets surrounding the rotor called ...
A synchronous motor is an AC motor wherein, at steady state, the rotation of the shaft is synchronized with the frequency of the supplied current; the rotation period is exactly equal to an integral number of AC cycles. Fig. 1 – Synchronous Motor. These motors contain multi-phase AC electromagnets on the stator of the motor that create a ...
The construction of this type of rotor is very simple and rugged. So, almost 80% of the induction motor is a squirrel cage induction motor. The rotor consists of a cylindrical laminated core and has slots on the outer periphery. The slots are not parallel but it is skewed at some angle. It helps to prevent magnetic locking between the stator ...
A servo motor is a type of motor that has a high degree of precision in rotation. Servo motors often have a control circuit that provides feedback on the current position of the motor shaft; this feedback allows them to rotate with great precision. A servo motor is used when you wish to spin an object at a specified angle or distance.
