Description:

Rated operating mode – continuous.

АK, АKЗ motors are started manually with the help of the starting rheostat and automatically by magnetic station. At a customer’s request the starting rheostat or magnetic station can be delivered with the electric motor as a complete unit.

The motors enable two cold starts successively or one hot start.

Construction mounting arrangement of the motor – horizontal, without bed plate, with two shield bearings, one free shaft end coupled with the operating mechanism with a half-coupling.
АK, АKЗ motors are designed closed. They operate with forced ventilation by clear air in closed premises with dirty environment.

Insulation of stator winding belongs to heat-resistance class not lower “В”.

Stator winding has six outlet ends fixed on four insulators in the terminal box. Phase connection – “star”.

The terminal box is fixed on the right side if you are looking on the free shaft end (left location is specified in the order).
Motors have left and right sense of rotation. Sense of rotation is changed only in rest state.

The motor designation is decoded as follows:

АК, АКЗ – ХХ-ХХХ-Х-ХХХХ4

АК – asynchronous motor with phase rotor
АКЗ  – closed asynchronous motor with phase rotor
XX – gabarit of the electric motor
XXX – overall length of the stator core, in cm
X – number of poles
ХХХХ – climatic construction
