To provide an electric motor unit for efficiently cooling a controller for controlling the operations of an electric motor, and a self-propelled electric vehicle equipped with the electric motor unit.SOLUTION: A self-propelled electric vehicle 100 is equipped with an electric motor unit 120 in a frame 101 supporting a front wheel 103 and a back wheel 108. The electric motor unit 120 has an electric motor 121, a controller 132, and an air blower 140. In the electric motor 121, a rotor accommodation space 126 is formed in a main housing 124 and a part of the main housing 124 is covered with a second housing 130 so that a controller accommodation space 131 is formed. The air blower 140 is arranged across the rotor accommodation space 126 and the controller accommodation space 131 by the main housing 124 and the second housing 130.SELECTED DRAWING: Figure 2

    【課題】電動機の作動を制御するコントローラについても効果的に冷却することができる電動機ユニットおよびこの電動機ユニットを搭載した自走式電動車両を提供する。【解決手段】自走式電動車両100は、前輪103および後輪108を支持するフレーム101に電動機ユニット120が取り付けられている。電動機ユニット120は、電動機121、制御装置132および送風機140を備えている。電動機121は、メインハウジング124の内部にロータ収容空間126が形成されているとともにメインハウジング124の一部を第2ハウジング130が覆って制御装置収容空間131が形成されている。送風機140は、メインハウジング124および第2ハウジング130を介してロータ収容空間126と制御装置収容空間131とに跨った状態で配置されている。【選択図】 図2
