FIELD: electrical engineering.
SUBSTANCE: in the method for determining the technical condition of an asynchronous motor in the process of launch the acceleration time is assumed as the parameter being diagnosed whereby one judges on the asynchronous electric motor technical condition. The acceleration time value will depend on the following parameters: mains voltage, current frequency, rotor inertia momentum, the motor rated speed, the motor rated power, design parameters (slot type, windings position etc), magnetic flux non-uniformity. Diagnostics is performed by way of comparing the obtained value of the acceleration time of the motor being controlled to the preset theoretical or reference value.
EFFECT: determination of the motor technical condition and evaluation of the machine performance in the capacity of the process being fulfilled.
