ABSTRACT:
Disclosed is an adapter unit for converting a standard electrical motor into a variable-speed electrical motor. The pre-assembled unit includes a tachometric generator and a ventilating electrical motor driving a fan wheel. Both the generator and the ventilating motor with the wheel are arranged in a common adapter housing which is integrally formed with a tubular connecting piece directed radially to the driving shaft of the motor to be adapted and supporting on its outer end a terminal box. Connecting cables for the tachometric generator and for the ventilating electrical motor are guided through the connecting piece to the terminal box.
