Abstract: A motor driver is provided. The motor driver includes an AC/DC converter, a DC/AC converter, a heat dissipation plate and a busbar module. The AC/DC converter converts an AC input power to a DC power and includes a first thermal module, a second thermal module, a first capacitor pack and a second capacitor pack. The DC/AC converter is connected with the AC/DC converter, converts the DC power to an AC output power, and includes a third thermal module. The heat dissipation plate includes an upper surface and a lower surface. The first thermal module is disposed on the upper surface. The second thermal module and the third thermal module are disposed on two opposite surfaces, respectively. The first capacitor pack is disposed on the upper surface. The second capacitor pack is disposed on the lower surface and corresponding to the first capacitor pack.
