Method of controlling motor-driven washing machine and control system for the same
First Claim
1. A method of controlling a motor-driven washing machine, the method comprising the steps of:
- determining weight of a load of clothes being contained in a tub;
braking the motor according to a slow brake logic if a interruption of the motor is ordered when the motor speed is less than or equal to a third predetermined speed(W3);
selecting one of a plurality of rapid-brake logics on the basis of the measured weight of a load of clothes and braking the motor according to the selected rapid-brake logic if a interruption of the motor is ordered when the motor speed is greater than or equal to a third predetermined speed(W3) and a spin period is determined to be less than a predetermined period of time(E); and
braking the motor according to the selected rapid-brake logic based on the measured weight of a load of clothes when the motor speed is greater than or equal to a third predetermined speed(W3) if a interruption of the motor is ordered after the spin period is determined to be greater than or equal to the predetermined period of time(E) and the motor power is turned off.

Abstract
A method of controlling a motor-driven washing machine. The method includes increasing a speed of a motor from zero to a first predetermined speed W1. Reducing the motor speed from W1 to a second predetermined speed W2 and measuring the deceleration period. Increasing the motor speed from W2 to a third predetermined speed W3 and braking the motor according to a slow brake logic if a first interruption of the motor is ordered during the step of increasing the motor speed from W2 to W3. Increasing the motor speed from W3 to a fourth predetermined speed W4 and selecting one of plurality of rapid-brake logics on the basis of the measured deceleration period and braking the motor according to the selected rapid-brake logic if a second interruption of the motor is ordered during the step of increasing the motor speed from W3 to W4.
