Construction of Inverted or rotor-fed induction Motor
The stator features a three-phase winding that will feed From the three-phase power source. The rotor is likewise winding in three stages in a star arrangement. Each coil finishes at the slip ring. The rotor features three slip rings because the rotor winding is three-phase. The slip rings are positioned on the rotor shaft. The brushes travel on the slide rings.
The measuring coils are inserted into the rotor slots and routed to the shaft’s extra slip rings. The stator winding slots include the same number of measuring coils. This motor may be driven from either the stator or the rotor side. Because of the way this sort of motor is developed, mechanical sensitive balance may be observed without the need of centrifugal force. The rotor current may be induced by varying the stator current or magnetic field.
The inverted or rotor fed induction motor’s stator has three short-circuited phase windings. The rotor also features three-phase windings that are coupled in a star arrangement. Each coil finishes at the slip ring. The slip rings are positioned to the rotor shaft, and the brushes ride on them. The slip rings connect the three-phase power supply to the motor.
Inverted or Rotor Fed Induction Motor
Induction motors consist of a stationary stator and a spinning rotor. In normal operation, the stator draws power from the alternating current mains. In an inverted or rotor-fed induction motor, the rotor contains three-phase windings from which a three-phase AC supply is supplied. The winding of this rotor must be in a star arrangement. This inverted or rotor-fed induction motor is used experimentally because it exhibits mechanical revolving qualities in both the stator and the rotor.
In a traditional three-phase induction motor, the supply mains provide a balanced three-phase feed to the motor stator. In contrast, an inverted or rotor-fed induction motor contains three-phase windings and is powered by a three-phase balanced supply from the alternating current mains. The rotor windings of the inverted induction motor must be in a star configuration.
