PROBLEM TO BE SOLVED: To provide a drive device for an in-wheel motor vehicle that can reduce size, weight and cost.SOLUTION: A motor drive device for drive wheels of a vehicle comprises: a plurality of in-wheel motor parts 3A-3D arranged on at least two drive wheels among a plurality of drive wheels; and a plurality of motor drive devices 4A-4D for controlling these in-wheel motor parts 3A-3D respectively. Each of the motor drive devices 4A-4D consists of a smoothing circuit 11, an inverter controller 12, an inverter part 13, and a cooling unit. The plurality of motor drive devices 4A-4D are gathered to one position and arranged in the same case. Among the plurality of motor drive devices 4A-4D, a smoothing capacitor C is shared with each other. The inverter controller 12 is a control system driven by a PWM system. The plurality of motor drive devices 4A-4D have the same PWM cycle, and on-off timings of the drive elements are shifted from each other.

    【課題】小型化、軽量化、および低コスト化が可能なインホイールモータ車両の駆動装置を提供する。【解決手段】複数の駆動輪のうち少なくとも2つの駆動輪に配置した複数のインホイールモータ部3A〜3Dと、これらのインホイールモータ部3A〜3Dをそれぞれ制御する複数のモータ駆動装置4A〜4Dとを備える。モータ駆動装置4A〜4Dは、平滑回路11、インバータ制御部12、インバータ部13、および冷却器からなる。複数のモータ駆動装置4A〜4Dを1箇所に集めて同一ケース内に配置する。複数のモータ駆動装置4A〜4Dの間で、平滑コンデンサCを互いに共有する。インバータ制御部12は、PWM方式で駆動させる制御方式であり、複数のモータ駆動装置4A〜4Dは、互いにPWMの周期が等しく、かつ前記駆動素子のオン・オフタイミングを互いにずらす。【選択図】図3
