1. Presentation of the equipment

The “Motor feeder training modules” are used to study and produce the power control of an electric

motor 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 of

protection and control material): ref. MD1AA740.

The Tesys U option, integrated motor feeder, modular and communicating, easy to

implement: 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 devices

contained in the basic module MD1AA740 are required.

Devices not supplied in the modules:

- motors,

- containment cabinet.

Use of 1.5 kW power motor is recommended.

1.3 Main functions

The “basic module” is used to:

quickly and easily assemble and disassemble all the devices.

ensure the electric distribution and the protection of power and control diagram.

perform a mounting with direct motor starting, reverse starting and star-triangle starting with

classical components.

The “Tesys U module” proposes:

the implementation of a new generation of direct motor starting, reverse starting and star-

triangle starting integrated in modular components.

The “power drive module” proposes:

the implementation of an integrated component allowing the soft starting and shut down of a

motor.

the implementation of a frequency converter.
