Sample text

The following drawing illustrates one instant in time during which current flow through winding A1 produces a north pole. The expanding field cuts across an adjacent rotor bar, inducing a voltage. The resultant magnetic field in the rotor tooth produces a south pole. As the stator magnetic field rotates the rotor follows. A1 N B2 C2 S C1 B1 A2 38 Slip There must be a relative difference in speed between the rotor and the rotating magnetic field. If the rotor and the rotating magnetic field were turning at the same speed no relative motion would exist between the two, therefore no lines of flux would be cut, and no voltage would be induced in the rotor.

In the following illustration phase A is connected to phase A of the power supply. Phase B and C would also be connected to phases B and C of the power supply respectively. A1 (N) B2 To Phase A C2 + A B C 0 _ C1 (S) A2 B1 To Phase A Phase windings (A, B, and C) are placed 120° apart. In this example, a second set of three-phase windings is installed. The number of poles is determined by how many times a phase winding appears. In this example, each phase winding appears two times. This is a two-pole stator.

Slip is dependent on load. An increase in load will cause the rotor to slow down or increase slip. A decrease in load will cause the rotor to speed up or decrease slip. Slip is expressed as a percentage and can be determined with the following formula. % Slip = NS - NR NS x 100 For example, a four-pole motor operated at 60 Hz has a synchronous speed (NS) of 1800 RPM. 8%. 9% Wound rotor motor The discussion to this point has been centered on the more common squirrel cage rotor. Another type is the wound rotor.
