How do you differentiate the converter motor from the general motors?
Variable frequency motor and the common one of the biggest difference is the fan cooling way, general motors was the cold, the fan on the motor shaft, changes with the rotational speed of the motor, so the ordinary motor at low frequency heat dissipation is not ideal. Frequency conversion motor cooling fan is behind the motor equipped with a cooling fan, need an external power, the fan will not be affected by the speed of the motor, is a strong refrigeration.
rter, the motor is the same, but the problem of controlling the frequency converter
The converter motor is equipped with an independent axial flow fan in the hood of the wind shield.
