The present invention addresses the problem of providing a motor unit capable of effectively cooling even a controller for controlling the operation of a motor, and a self-propelled electric vehicle equipped with the motor unit. A self-propelled electric vehicle (100) in which a motor unit (120) is attached to a frame (101) that supports a front wheel (103) and a rear wheel (108). The motor unit (120) is provided with a motor (121), a control device (132), and a blower (140). In an electric motor (121), a rotor housing space (126) is formed inside a main housing (124), and a second housing (130) covers a part of the main housing (124) to form a control device housing space (131). The blower (140) is disposed across the rotor housing space (126) and the control device housing space (131) across the main housing (124) and the second housing (130).
本发明的课题为提供一种针对控制电动机的运作的控制器也可有效地冷却的电动机单元,以及装配所述电动机单元的自行式电动车辆。本发明的解决手段为一种自行式电动车辆(100),其于支撑前轮(103)及后轮(108)的车架(101)安装有电动机单元(120)。电动机单元(120)具备电动机(121)、控制装置(132)及送风机(140)。电动机(121)中,于主外壳(124)的内部形成有转子收纳空间(126),并且第二外壳(130)覆盖主外壳(124)的一部分而形成控制装置收纳空间(131)。送风机(140)是隔着主外壳(124)及第二外壳(130)而以跨越转子收纳空间(126)及控制装置收纳空间(131)的状态配置。
