Title: Motor control method for washing machine
Inventor: KIMU HAGU UON
IPC: H02P6/06
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce current required for a motor by applying the constitution that a hole sensor position signal is inputted on the basis of an EC motor position, and finding a rotational direction instruction drive logic during a washing mode so as to modulate pulse breadth for voltage instructions obtained from a speed instruction and an actual speed. SOLUTION: An EC motor position is detected at a step 1, and a discrimination is thereby made between a washing mode to input a hole sensor position signal and a spin drying mode at a step 2. When the mode is for washing, a rotation direction instructing drive logic at a power factor angle of β1 is calculated, according to a detected rotation direction instruction at a step 3. Also, a voltage instruction is found from an EC motor speed instruction and the actual speed of the EC motor at a step 6, and pulse width is modulated for outputting on the basis of drive logics obtained from logic calculations for a power factor angle clockwise or a counterclockwise direction at steps 4 and 5. According to this construction, the power factor angle increases and the EC motor speed increases. Also, torque is reduced.  As a result, a washing zone can be kept at low speed and high torque, and a spin drying zone at high speed and low torque, thereby reducing an input current value.
