Operating principles. The two main types of AC motors are induction motors and synchronous motors. The induction motor (or asynchronous motor) always relies on a small difference in speed between the stator rotating magnetic field and the rotor shaft speed called slip to induce rotor current in the rotor AC winding.
A DC motor in simple words is a device that converts electrical energy (direct current system) into mechanical energy. It is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article.
Synchronous Motors. Synchronous ac motors are constant-speed electric motors and they operate in synchronism with line frequency. The speed of a synchronous motor is determined by the number of pairs of poles and is always a ratio of the line frequency.
An electrical motor is such an electromechanical device which converts electrical energy into a mechanical energy. In case of three phase AC operation, most widely used motor is Three phase induction motor as this type of motor does not require any starting device or we can say they are self-starting induction motors.
LINEAR ACTUATORS. The term "linear actuator" covers a broad range of products. A linear actuator is a mechanical device that converts energy (power from air, electricity or liquid) to create motion in a straight line; contrasted with circular motion of a conventional electric motor.
