The invention relates to a regulating device () for a motor, comprising a housing () which can be associated with said motor and in which a control unit () and an actuator () 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 () comprises an electromagnetic switching element () and the control signal () for the same is designed as a timing signal which is measured&#x2014;taking into consideration at least one heat source inside or optionally outside the housing ()&#x2014;in such a way that the operating temperature of the electromagnetic switching element () is below an upper authorised limiting value.
