Product Code : SCL-EELE-13011
Indian Lab Suppliers supplies the Repulsion Motor Trainer (Product ID: 13011) as part of its electronics engineering lab equipment range. It is used to test a single-phase repulsion motor under load and to show how brush position controls its speed and direction.
Quick Answer
In a repulsion motor the stator is fed from single-phase AC, while the rotor has a commutator with short-circuited brushes; torque depends on the angle between the brush axis and the stator field axis. Moving the brushes changes the speed, and moving them to the other side of the field axis reverses rotation. The three listed experiments cover the speed-torque curve, efficiency with input power factor, and speed control with reversal. Readings come from a multifunction meter, a DC voltmeter, ammeter and torque meter panel, and a handheld tachometer. Switch off before shifting brushes or changing connections, and keep the rack earthed.
