AC electric motors with squirrel cage rotor of A, AЗ types are used to drive mechanisms, which don’t demand rotational speed adjustment (pumps, fans, and others).
Description:
These motors are rated for operation from AC network, 50 Hz, 6000 V.
The necessity to create some low-voltage asynchronous electric motors of these series appeared for last several days. Technical characteristics are given in the Table 37. Overall dimensions meet overall dimensions of motors for voltage 6000 V.
Rated operating mode – continuous.
А, АЗ motors are started directly, it is provided as at rated voltage, as at voltage reduction during the start up to 0,8 Unom.
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.
А, АЗ motors are designed protected. They operate with self-ventilation in closed premises with normal 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.
Motor designation is decoded as follows:
А, A3 – ХХ-ХХХ-Х-ХХХХ4
А – asynchronous motor with squirrel-cage rotor
AЗ – closed asynchronous motor with squirrel-cage rotor
XX – gabarit of the electric motor
XXX – overall length of the stator core, in cm
X – number of poles
ХХХХ – climatic construction
