PDF This paper explores the construction process of a linear induction motor LIM , the basic concepts behind key aspects of linear induction machines construction and the testing process of a working prototype. The single-phase induction motor is much the same in construction as the three-phase motor. There are two types of 3-phase induction motor based on the type of rotor used: Squirrel cage induction motor. Slip ring induction motor. Construction of Induction Motor

An AC motor is an electric motor driven by an alternating current AC. The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field , and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance saliency, or DC or AC electrical windings. Less common, AC linear motors operate on similar principles as rotating motors but have their stationary and moving parts arranged in a straight line configuration, producing linear motion instead of rotation. The two main types of AC motors are induction motors and synchronous motors.

Some of the advantages like low cost, rugged design less complex, and easy to maintain AC motors results in many of the industrial operations are performed with the use of AC drives than DC drives. AC induction motor is a special type of electric motor having its own typical characteristics and performance in terms of starting, speed control, protections, and so on. The performance over a wide range of applications makes three-phase induction motors accountable for 85 percent of the installed capacity of the industrial driving systems. The three-phase AC induction motor is a rotating electric machine that is designed to operate on a three-phase supply. This 3 phase motor is also called as an asynchronous motor. These AC motors are of two types: squirrel and slip-ring type induction motors.

An induction motor can be used for different applications with various speed and load requirements. Induction motors are used in almost all machinery system of the ship such as crane motor, propulsion motor, blower motor, seawater pump motor, and even small synchronous motor. An induction motor or asynchronous motor is an AC motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding.

Facebook Twitter. Three Phase Induction Motor:. The three phase induction motors are the most widely used electric motors in the industry. They run at essentially constant speed from no-load to full-load. However, the speed is frequency dependent and consequently, these motors are not easily adapted to speed control.
