Three Phase Induction Motors. Three phase motors are a type of AC motor that operates using the principle of electromagnetic induction. They differ from single-phase AC motors in that they use three-phase power, which provides smoother torque and higher efficiency. For a thorough understanding of three-phase induction …

The induction motor can be considered a three-phase transformer whose secondary, or the rotor, is short-circuited and revolves at the motor speed. Since the motor usually operates at balanced conditions, only a single-phase equivalent circuit is needed. When balanced three-phase currents flow in both stator and rotor windings, the …

Construction of Three Phase Induction Motor: Figure 8.1 shows the construction of three phase induction motor. A 3 phase induction motor has two main parts (i) stator and (ii) rotor. The rotor is separated from the stator by a small air-gap which ranges from 0.4 mm to 4 mm, depending on the power of the motor.

day. If time permits, we shall study it in a future experiment. The three phase IM is also one of the most commonly used three phase motors. The reason is the rugged construction of the motor and the absence of brushes. The figure above illustrates the per phase equivalent circuit of the IM. On the rotor side, the total resistance is R R s s R 2 s
