Reluctance Motor Construction Operation and Characteristics - There are very few single-phase motors which run at true synchronous speed and they do not require any external DC excitation for the rotor. Therefore, these motors are also called as unexcited single-phase synchronous motors.The efficiency and the torque developing capability of the single-phase sy

The Stepper Motor Classification based on the construction and principle of operation. These are:Variable reluctance motors,Permanent magnet motors,Hybrid stepping motors,Claw pole motors with permanent magnets

Thus Switched reluctance motors are self-starting motor. The control circuit continuously monitors the motor speed and input current. if the motor speed falls with respect to the reference, then the control considers as there is a requirement of high torque. Therefore, it increases the input current to the motor to meet the speed requirement.

These unique features that is different from the servo motor make the stepper motor to be well suitable for open loop control system wherein the precise position of the shaft is maintained with the exact number of the pulses without …

The working principle of the stepper motor is based on sequentially energising the stator winding which generates a rotating magnetic field and causes the rotor to rotate in discrete steps. This makes the stepper motors an indispensable component in …

Stepper motors operate with an external drive logic circuit. When a train of pulse is applied to the input of the drive circuit, the circuit supplies currents to the stator windings of the motor to make the axis of the air-gap field around in …
