    Abstract: A control and protection apparatus for an electric motor, comprising an inverter (3), a first converter (1), a temperature detection apparatus (7), and a second converter (2). The first converter (1) is used for generating, on the basis of an input signal, a first control signal to control working of the inverter (3). The temperature detection apparatus (7) is used for detecting the temperature of the electric motor (4) and for acquiring a temperature signal. The second converter (2) is used for generating a second control signal on the basis of the temperature signal detected and for providing the second control signal to the inverter (3). The inverter (3) is used for controlling wording of the electric motor (4) on the basis of the first control signal and of the second control signal. The control and protection apparatus for the electric motor is low in costs and high in safety and reliability.
