Abstract
A laundry appliance having a vibration detection device includes a frame, a drum received in the frame, and an electric motor assembly for driving the drum. The electric motor assembly includes an electric motor and an integrated motor controller mounted to the electric motor. An accelerometer as the vibration detection device is provided in the motor controller for detecting vibration of the drum. By integrating the accelerometer to the electric motor assembly, the laundry machine can more accurately detect vibration of the drum and the time and cost for assembling the washing machine are reduced.
