The present disclosure provides an electric drive device, an electric drive system and an electrical device. The above-described electric drive device includes a first motor, a second motor, a transmission mechanism and a controller. The second motor is spaced apart from the first motor in an axial direction of the first motor. The transmission mechanism is arranged between the first motor and the second motor. The controller is arranged between the first motor and the second motor. At least part of the controller and at least part of the transmission mechanism are arranged on two opposite sides of a rotation shaft of the first motor. Embodiments of the present disclosure provide an electric drive device by disposing the transmission mechanism and the controller between the first motor and the second motor, and disposing at least part of the controller and at least part of the transmission mechanism on opposite sides of a rotation shaft of the first motor, such that a space of the rotation shaft of the first motor on the side facing away from at least part of the transmission mechanism is effectively utilized, thereby effectively reducing a volume of the electric drive device.
