GOST A4 Series High Voltage Motor

Three-phase asynchronous electric motors with short-circuit rotor series A4 are designed to drive mechanisms that are not requiring regulation of the speed of rotation (pumps, ventilators (ry, smoke exhausters, etc.).

The motors are designed to operate on a 50 Hz AC mains voltage of 3000 V, 6000 V and 10000 V.

Motors with a voltage of 3000 V are manufactured in the dimensions of motors with a voltage of 6000 V with the same power. The stator current of motors with a voltage of 3000 V is twice that of motors with a voltage of 6000 V.

Climatic version of 3000 V and 6000 V motors - U3, T3.

Climatic version of motors with voltage 10,000 V - U3.

Nominal operating mode - continuous S1.

Engine design - IM1001.

Cooling method of motors - ICA01.

Protection degree of motors - IP23, terminal boxes% IP55.

Direct start of motors. Motors allow two cold starts in a row or one hot start. The interval between subsequent starts is not less than three hours, the number of starts is not less than 2000 during the operation period, but not more than 250 starts per year during the warranty period.

The motors are equipped with grease lubricated rolling bearings. The connection of the motors with the drive mechanism is carried out by means of an elastic coupling. Insulating materials of the stator winding of the heat resistance class not lower than "B". The stator winding insulation is thermosetting type "Monolit - 2". The stator winding has six leads out, fixed on four insulators in the terminal box. The phase connection of the windings is star.

Motors allow right and left rotation. The reversal of the direction of rotation is carried out only from rest.

Motors can be fitted with SKF or FAG bearings
