A4236 A4236 A4236 A4236 ---- REPULSION MOTOR REPULSION MOTOR REPULSION MOTOR REPULSION MOTOR

The repulsion motor is a single phase motor with a collector rotor and short-circuited brushes. An alternating voltage applied to the stator, depending on the brushes position, induces an alternating voltage in the rotor winding. If the brushes are aligned to the neutral plane no current is induced and no torque is developed; if they are at 90° to the neutral plane, maximum current is induced but no torque is developed because the stator and rotor fluxes are in phase.

If the brushes are at some intermediate position, a torque is developed which is at maximum value when they are at approximately 70°. Their optimum position can be determined experimentally. For education purposes the motor is equipped with a connection board with 4 mm terminals and silk printed diagram designed for clear understanding of the internal logic and connections

A4238S A4238S A4238S A4238S ---- SHADED POLES MOTOR SHADED POLES MOTOR SHADED POLES MOTOR SHADED POLES MOTOR The shaded poles motor is a single phase induction motor with two laminated poles on the stator and a squirrel cage rotor. The poles have a slot cut across the lamination and around one of the two parts a copper coil, called shading coil, is wound. The exciting winding is wound across the poles. When an AC source is applied to the poles windings the axis of the magnetic field shifts

from the unshaded part to the shaded part of the poles thus inducing the rotor into a rotation. For education purposes the motor is equipped with a connection board with 4 mm terminals and silk printed diagram designed for clear understanding and connections.

This is a series of educational motors/generators that are basically industrial models especially equipped to be suitable for training. For this purpose the windings ends are connected to 4 mm safety sockets in a metal housing on top of which a clear electrical drawing shows the internal logic. The students can therefore easily understand operation and windings connections. The machine has two excitation windings: one for series and one for shunt excitations. The units can be supplied with an experiment manual which explains typical exercises that can be executed on these machines. A comprehensive set of accessories and a joint allow easy and quick coupling with other machines or with a brake.

The instructor activates the switches to simulate the faults and assigns to the students the task of identifying, analyzing and explaining them. When all the fault injection switches are in

their normal position the motor functions as a standard squirrel cage motor. It is supplied with a manual that explains the faults that can be simulated and the related switch settings. The following faults can be simulated: − Loss of supply phase − Open phase − Shorted phases − Leakage to ground
