1. Presentation of the equipment

The Motor feeder training modules are used to study and produce the power control of an electricmotor in various start-up possibilities.

1.1 Composition

The module is composed of the following references:

The basic module, traditional electromechanical (mounting plate kit, supply kit and a set ofprotection and control material): ref. MD1AA740.

The Tesys U option, integrated motor feeder, modular and communicating, easy toimplement: ref. MD1AA740T

The power drive system and soft start option: ref. MD1AA740V

This equipment Motor feeder training module" is proposed to study and use the control of three-phase asynchronous motors with 1.5kW power, following several diagrams and solutions.

The components and assembly devices proposed are the same as those used in industry.

NB: To produce motor feeders with options MD1AA740T and MD1AA740V, the devicescontained in the basic module MD1AA740 are required.

Devices not supp lied in the modules:

- motors,

- containment cabinet.

Use of 1.5 kW power motor is recommended.
