A4236 - REPULSION MOTOR If the brushes are at some intermediate position, a torque is developed which is at maximum value when they are at approximately 70째. Their optimum position can be determined experimentally.

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.

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

If the brushes are aligned to the neutral plane no current is induced and no torque is developed; if they are at 90째 to the neutral plane, maximum current is induced but no torque is developed because the stator and rotor fluxes are in phase. TECHNICAL DATA Power supply Approx. power

A4246 - DC POLY EXCITATION MACHINES 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 one shunt and two series excitation windings. 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.

A42FS â&#x20AC;&#x201C; THREE PHASE MOTOR WITH FAULT SIMULATOR The ends of an induction motor stator windings are connected to a series of switches, hidden within an Electron terminal box above the motor, and from here to the 4mm safety connectors of the same box. 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
