A motor drive unit for an in-wheel motor includes a housing and one and capacitors and solid state switching devices arranged within the housing. The housing includes: a lower compartment including a bottom plate, sidewalls which extend from the bottom plate, and end sides at the transverse ends of the sidewalls and bottom plate, wherein the bottom plate is provided with cooling channels for receiving a liquid coolant; a separation plate covering the lower compartment, wherein the separation plate is in thermal contact with the sidewalls and with the capacitors. The solid state switching devices are arranged in the lower compartment between the bottom plate and the separation plate and in thermal contact with the bottom plate, wherein the capacitors are connected to DC bus bars and are arranged at a side of the separation plate that faces away from the lower compartment.
