Fan and Blower Drives
Squirrel cage motors, which are fed by frequency converters, are used more frequently for heavy starting in fan or blower drives. This starting method allows for the reduction of the motor’s starting current and leads to energy conservation, even in the case of speed control in the operation. The fan’s frequent high mass moments of inertia should be taken into account. In the case of extremely high torques, our slip ring motors are used.
