Vertical asynchronous electric motors of 4АОВ type with squirrel-cage rotor are used to drive mechanisms with easy starting conditions (pumps and other mechanisms with similar characteristics).
Description:
The motors are designed to operate from AC network, 50 Hz, 6000 V.
Rated operating mode of the motors – continuous (S1) by GOST 183-74.
Constructive mounting arrangement – IМ3011.
Degree of protection of the motor- IР44, outlet device – IР55, housing of the outer fan – IР21.
Winding insulation of the stator is thermosetting – “Monolith-2”.
Cooling method is self-ventilation.
Phase connecting circuit – “star”.
The motor designation is decoded as follows:
4-АОВ-ХХХ-Х-Х-Х-Х
4 – Serial number of the series
АОВ – Asynchronous blown vertical
ХХХ – Height of rotational axis, mm (frame by classifier “Unified system for design documentation”)
Х – Symbolic notation of the motor length
Х – Number of poles
Х – Climatic version
Х – Installation category
