Electric motors with squirrel cage rotor are used to drive pumps, fans, smoke exhausters and other mechanisms, which don’t require rotational speed adjustment, and they are rated for continuous operating mode S1 from AC network 50 Hz.
Description:
The motors meet the IEC requirements.
The motors are manufactured for voltage 6000 V.
Construction mounting arrangement – IM1001.
The motors are produced with frictionless bearings, with one shaft end.
Outlet ends are removed in the terminal box and connected in “star on four insulators”.
Degree of protection for the outlet box – IP54.
Degree of protection for the motors – IP23.
The motors are cooled with self-ventilation.
The motor designation is decoded as follows:
А5К
А – asynchronous motor with squirrel-cage rotor;
5 – series number;
К – made in Novaya Kakhovka.
ХХХ – Height of the axis of rotation in mm
ХХХ – Rated power, kW
2, 4, 6 – Number of poles
У3 – Climatic construction and allocation category
