Asynchronous double-speed electric motors of АОД type are designed to drive mechanisms with heavy starting conditions (smoke-exhausters, fans, etc.).

Description:

These motors are rated for operation from AC network, 50 Hz, 6000 V.
Rated operating mode – continuous S1.

Motor run is direct, it is realized both at rated voltage, and at mains voltage reduction during the start up to 0,8 Unom. Starting should be incremental-type (initially with lower rotational speed, then it is skipped to the top speed).

They enable two cold starts successively or one hot start. The interval between the subsequent starts is not less than three hours. Total quantity of starts is 500 per a year and 1000 starts during the service life.

Constructive mounting arrangement – closed, blown, with self-ventilation, horizontal shaft, on foundation girders or bedplate, with panel plain bearings with autonomous ring or combined (forced and ring) lubrication, with one free shaft end for coupling with the working mechanism by a half-coupling.
The air cooler “air-to-air” can be installed on the top of the frame. Sense of rotation is right. Motors with left sense can be manufactured (specified in the contract).

Stator winding insulation is thermosetting by “F” class.

Stator winding has six terminals brought to their box. Phase connecting circuit – “star”.
The motors are delivered with build-in electric heaters.

The motor designation is decoded as follows:
АОД – Asynchronous blown motor with squirrel-cage rotor
ХХХХ/ХХХХ – Power, kW
ХХ/ХХ – Number of poles
У1, Т1 – Climatic construction and allocation category
