General introduction :

This system permit to wire by the students different types of asynchronous motor starting.

It must be manufactured around an electric hoist of 125 kg capacity with a containment cabinet integrated to the whole.


Frame :

- Welded stainless steel,

- Protection of the working area by a safety grid,

- Access door to the load equipped with a security end stroke sensor and a lock key.


Teaching objectives

- Mono speed asynchronous motor starting,

- Bi speed asynchronous motor starting,

- Frequency variation of the asynchronous motor,

- Logic control of the brake in lifting mode,

- Safety devices management,

- Installation sizes control,

- Presence or not of voltage (system capable to be used for the electric authorization),

- Installation and verification of the good working after wiring,

- Maintenance and setting of the system (thermal relay, adjustment of the end stroke sensors... ).


Technical specifications


Lifting Mechanism:

- Electrical bi-speed hoist with chain, 125 kg capacity with brake

- Bi-speed lifting Motor 200 W - 400 V 3 phase,

- Linear speeds: 2 m/mn and 8 m/mn,

- Working end stroke: high and low,

- Out stroke: high and low (forcing by key button),

- Load constituted of a metallic mass of 15 kg and 11 modular elements of 10 kg.


Control part:

The containment cabinet is an integral part of the system and is able to receive the platen wired by the student . We propose in option different set of equipments :

- 1 wired platen including all the components for a direct starting

- 1 wired platen including all the components with speed driver ATV58

The containment cabinet also include a differential circuit breaker, a end stroke security sensor on the door of the cabinet and one logic block security device that allows the electricity supply of the platen.

A fast fixing device and connectors permit a fast installation of the platens wired by the students.



General features:

- Dimensions (L x w x h) (basis) : 1000 x 1000 x 2300 mm,

- Power supply 3 x 400 V+T+N. 16A.
