Driving unit for use in potentially explosive environment in industrial plant in e.g. gas production, has electromotor energized for heating purpose based on detected temperature over control unit that comprises temperature sensor

摘要

The driving unit has a driven shaft driven with an electromotor (1), and a control unit provided for the electromotor, where the control unit comprises a temperature sensor. The electromotor is energized for heating purpose based on detected temperature over the control unit, where the driving unit comprises a housing (41). The electromotor is arranged in motor cases (2, 3), and the temperature sensor is arranged within the motor cases. A circuit board of the control unit is provided in the temperature sensor, and an engine shaft is coupled with a drive shaft over a gear box.
