Three phase induction motors series 1AY
Induction motors of 1AY series are special AC motors designed for powering from frequency converters. They are used most often in machine-tools, textile machines, fans, pumping equipments, drives for fork lift trucks or platform trucks.
At project of these motors all influences that appear in the powering from frequency converters have been solved. Therefore their operation is optimally adjusted without any loss in efficiency and without any additional vibrations and noise.
Motors of 1AY series are produced in four axial heights:
Motor frame is ribbed, and made from aluminium alloy.
Motors are equipped with independent ventilation, which enables to operate the motors in the range from minimal to nominal speed at nominal torque and further the operation at speed up to 6000 min-1 by a constant power. On customer’s demand it can also be up to 10 000 min-1.
The motors can be also equipped with an incremental or other speed sensor. Further all motors are equipped with thermal switches, which signalize attainment of winding temperature limit, given by used class of insulation. Current inlets of the motor, ventilation motor, thermal switch and speed sensor are lead to terminal box, equipped with cover and necessary bushings.
