Low-voltage asynchronous electric motors of AЧР series with squirrel-cage rotor are designed for mechanisms, which operate with an adjustable-frequency electric drive.

Description:

Protection degree of the motors – IP23.

The motors are made with frictionless bearings.

Asynchronous electric motors of А, ДАЗО, АОД series with squirrel-cage rotor can be used in structure of the adjustable-frequency electric drive and can be used with soft starters in most cases without additional improvement, if following conditions are performed:

– mechanism has quadratic moment- speed dependence;
– voltage on clamps of the electric motor should vary proportionally to square of supply voltage frequency;
– current waveform distortion factor of the motor is less 5%;
– working control range of supply voltage frequency from 20 to 50 Hz.

Power factor cosφ is kept constant.
