ABSTRACT:
The invention relates to a regulating device (1) for a motor, comprising a housing (2) which can be associated with said motor and in which a control unit (5) and an actuator (6) are arranged. Due to heat-related reasons, said device can only be used in an encapsulated manner, for example close to a motor. In order to solve this problem, the actuator (6) comprises an electromagnetic switching element (8a,8b) and the control signal (7) for the same is designed as a timing signal which is measured—taking into consideration at least one heat source inside or optionally outside the housing (2)—in such a way that the operating temperature of the electromagnetic switching element (8a,8b) is below an upper authorised limiting value.
