Abstract: An electric motor includes a motor main body and an inverter. The inverter is axially stacked on one end of the motor main body, and the inverter includes a gate driver, a control circuit, a capacitor module, a DC bus bar, a plurality of power modules and a plurality of AC bus bars. The power module includes a plurality of AC output terminals, a plurality of DC input terminals and a plurality of signal terminals, and the AC bus bars are respectively connected to corresponding AC output terminals and extend downward to a motor coil of the motor main body. The power modules and the corresponding DC input terminals are annularly arranged around the capacitor module, the DC bus bar is extended and electrically connected to the corresponding DC input terminals and the capacitor module.
