An improved method for detecting a laundry weight in a washing machine employing a sensorless BLDC motor is provided. The motor is rotated until the washer reaches a first speed. The washer then operates in a torque control mode for a predetermined amount of time, and a laundry weight is then determined based on a speed of the motor after the predetermined amount of time has elapsed. In this manner, laundry weight can be accurately determined and the laundry can be effectively washed. Additionally, since a washing machine employing this improved method for detecting does not require a hall sensor and its peripheral circuit manufacture is simplified, and thus cost may be reduced.
