CONTROLLER FOR ACTUATING AN ELECTRIC MOTOR, ELECTRIC MOTOR AND SYSTEM HAVING A CONTROLLER AND ELECTRIC MOTOR

摘要

Controller (1) for actuating an electric motor (2), wherein the controller (1) has: - a temperature sensor interface (3) for connecting an external temperature sensor (4), wherein the temperature sensor (4) is provided for monitoring the temperature of the electric motor (2), and - a monitoring unit (5) designed to evaluate at least one temperature-dependent property of the temperature sensor (4) for monitoring the temperature of the electric motor (2) and, on the basis of and in addition to the temperature monitoring, to interchange data with the electric motor (2) via the temperature sensor interface (3).
