Problems solved by technology

[0003] However, after the washing machine is used for a long time, the connection between the motor adapter and the washing tub may become loose. At this time, the motor adjusts the motor speed after receiving the speed control command, but due to the loose connection between the motor adapter and the washing tub, causing The rotation speed of the motor adapter and the washing tub is not synchronized, and the load of the motor fluctuates greatly, which is very easy to cause the washing machine to spin and damage the washing machine. Therefore, there is an urgent need for an effective method to control the washing machine motor. It is very important to ensure the normal and stable operation of the motor.

Embodiment 1

[0022] Such as figure 1 As shown, a motor control method according to an embodiment of the present invention includes the following steps:

[0023] S1: Divide the 0-T time after the washing machine starts into two consecutive time periods, send the first speed control command to the motor so that the motor rotates according to the first speed control command in the first time period, and send the first speed control command to the motor Sending a second rotational speed control command to make the motor rotate according to the second rotational speed control command within a second time period, the first and second rotational speed control commands respectively include first and second rotational speed accelerations, and the first rotational speed acceleration is positive, and the second speed acceleration is negative;

[0024] S2: Obtain the rotation speed change curves of the washing tub and the motor within the detection time period, the opening time of the detection time ...

Embodiment 2

[0032] An embodiment of the present invention provides a washing machine, which includes a washing tub; a motor; a memory; a processor; and a computer program;

[0033] Wherein, the computer program is stored in the memory, and is configured to execute the motor control method described in Embodiment 1 by the processor, so as to control the motor to accelerate its speed.

Embodiment 3

[0035] An embodiment of the present invention provides a storage medium readable by an electronic device, the storage medium readable by an electronic device can store a program, and when the program is run on the electronic device, the electronic device executes the method described in Embodiment 1.

Abstract

The invention discloses a motor control method, a washing machine and an electronic equipment readable storage medium. The method comprises the steps: dividing the 0-T time after the washing machine is started into two continuous time periods, enabling the motor to rotate according to a first rotating speed control instruction in the first time period and enabling the motor to rotate according to a second rotating speed control instruction in the second time period; obtaining a rotating speed change curve of the washing barrel and the motor in a detection time period, wherein the starting time of the detection time period is in the first time period and the ending time is in the second time period; judging whether the overlap ratio of the rotating speed change curves of the washingbarrel and the motor in the detection time period exceeds a preset proportion threshold value or not; if not, sending a motor rotation stopping instruction to the motor to control the motor to stop rotating and then the washing bucket stops rotating; and if yes, the washing machine enters a normal working state. The defects in the prior art can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of washing machines, in particular to a motor control method, a washing machine and a readable storage medium for electronic equipment. Background technique [0002] At present, the motor and the washing tub are the key components in the washing machine. A motor adapter is connected between the motor and the washing tub. When the washing machine is in normal operation, the motor drives the motor adapter to rotate, and then drives the washing tub. Spin to wash clothes. [0003] However, after the washing machine is used for a long time, the connection between the motor adapter and the washing tub may become loose. At this time, the motor adjusts the motor speed after receiving the speed control command, but due to the loose connection between the motor adapter and the washing tub, the The speed of the motor adapter is not synchronized with that of the washing tub, and the load of the motor fluctuates greatly...
