Provided is a motor module that can improve heat dissipation. This motor module 1000 comprises: a motor 200 that has n phases of windings (n being an integer that is 3 or greater); a first circuit board CB1 that is connected to a first power supply 410; a first inverter 120 that is mounted on the first circuit board and connected to the n phases of windings; a power system power supply circuit that is mounted on the first circuit board and steps the power supply voltage of the first power supply up or down; a first heat sink 511 that thermally contacts the first circuit board; a second circuitboard CB2 that is connected to the second power supply; and a second inverter 130 that is mounted on the second circuit board and connected to the n phases of windings. A rotor 230 of the motor, thefirst heat sink, the first circuit board, and the second circuit board are arranged, in that order, along the direction of the rotational axis of the rotor.

    提供马达模块,能够改善散热性。本公开的马达模块(1000)具有:马达(200),其具有n相的绕组,n为3以上的整数;第1基板(CB1),其与第1电源(410)连接;第1逆变器(120),其安装于第1基板,与n相的绕组连接;功率系统电源电路,其安装于第1基板,对第1电源的电源电压进行降压或升压;第1散热器(511),其与第1基板热接触;第2基板(CB2),其与第2电源连接;以及第2逆变器(130),其安装于第2基板,与n相的绕组连接。沿着马达的转子(230)的旋转轴线的方向,依次配置有转子、第1散热器、第1基板以及第2基板。
