The W60 line motors were designed to meet the requirements of several industrial applications, such as compressors, pumps and fans, ensuring high 

Even after applying full voltage to the stator winding, the rotor of a 3 phase induction motor fails to start.) Magnetic hum gets reduced hence motor operation 

Direct on line starters are commonly used to start small motors, especially 3 phase squirrel cage induction motors. As we know, the equation for armature current in the motor. The value of back emf (E) depends upon speed (N), i.e. E is directly proportional to N. At starting, the value of E is zero. So starting current is very high.

of three-phase squirrel-cage induction motors, such as the motor speed, torque, Interchanging the power connections to any two of the stator.

Starting of 3-Phase Induction Motors The induction motor is fundamentally a transformer in which the stator is the primary and the rotor is short-circuited secondary. At starting, the voltage induced in the induction motor rotor is maximum (Q s = 1). Since the rotor impedance is low, the rotor current is excessively large.

A 3 phase squirrel cage induction motor is a type of three phase induction motor which functions based on the principle of electromagnetism.

Schematic representation of a 3-phase squirrel cage induction motor. Characteristics of Squirrel Cage Induction Motor Starting current: The starting current is about 5 to 6 times the full load current, at no load the current is less and increases with the increasing of load.

Lets see the construction of a three phase stator. The three phase windings are placed on the slots of laminated core and these windings are electrically spaced 120 degrees apart. These windings are connected as either star or delta depending upon the requirement.

The rotating magnetic field. • The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating. The

These 3 phase motor is supplied with 3 three-phase AC supply and is widely used in ships for heavier loads.3 phase induction motors are of two types, squirrel cage and slip ring motors.Squirrel cage motors are widely used on ships due to their rugged construction and simple design, few e.g. of their applications are: Lifts. Cranes. Automatic Telephone Exchange

The construction of squirrel cage induction simple and rugged. Construction of slip ring induction motors needs slip rings, brushes, short-circuiting device, etc. This type of motor has less overhang and better space factor in slots. These motors have the highest overhang and poor space factor in slots. Cost and maintenance are less.

The rotating field due to stator currents and the rotor currents react to produce force on the rotor conductors and the torque. Fig. 1: Three Phase Induction Motor To understand this more clearly, assume that the stator field is rotating in an anticlockwise direction and the rotor is stationary as illustrated in Fig. 2 (a).
