The invention relates to a cooling device of an electric motor, a related power assembly and a vehicle. The cooling device (28) of the electric motor (24) comprises:-a housing (40) defining an air duct (58) connecting the air inlet (52) to the at least one air outlet (56),-a fan (42) mounted within the housing (40), configured to drive an air flow circulation, and-a measuring device (44) for measuring the rotational speed of the fan (42), consisting of a coding wheel (64) indirectly connected to the fan (42) and a speed sensor (66); the cooling device (28) comprises a support plate (46) which can be fixed to a rotor (32) of the electric motor (24). The fan (42) is separate from the support plate (46) and is fixed only on one of the faces (60A, 60B) of the support plate (46).

    本发明涉及电动机的冷却装置、相关动力总成和载具。电动机(24)的冷却装置(28)包括:‑界定通气管道(58)的机壳(40),通气管道(58)将进气口(52)连接到至少一个出气口(56),‑安装在机壳(40)内的风扇(42),其被构造为驱使气流循环,以及‑用于测量风扇(42)的转速的测量装置(44),其由与风扇(42)间接连接的编码轮(64)和速度传感器(66)组成;冷却装置(28)包括能够固定在电动机(24)的转子(32)上的支撑板(46)。风扇(42)与支撑板(46)是分开的,并且仅固定在支撑板(46)的其中一个面(60A、60B)上。
