Control method of protecting blender motor

Abstract

The invention provides a control method of protecting a blender motor. The control method of protecting the blender motor comprises the following steps: 101, starting a motor to drive a stirring portion to work; 102, detecting the rotation state of the motor, and outputting the rotating state signals of the motor; 103, judging whether a motor rotor is blocked in a first direction or not according to the rotating state signals, if the motor rotor is blocked in the first direction, controlling the motor rotor to rotate along a second rotating direction for a preset time and then shift to the first direction to rotate, and if the motor rotor is not blocked in the first direction, controlling the motor rotor to continue to rotate along the first direction; 104, and judging whether the times of the motor rotor shifting to the second direction to rotate from the first direction are up to a preset value or not, if the times of the motor rotor shifting to the second direction to rotate from the first direction are up to the preset value, shutting down the motor, and otherwise, repeating the step 103. The control method of protecting the blender motor can accurately detect the rotating state of the motor, and carry out corresponding protection.

Description

technical field [0001] The invention relates to a control method of a motor, in particular to a control method of a stirrer motor. Background technique [0002] In the wave soldering stirring equipment, the solder in the solder bath will automatically generate solder slag. In order to slow down the speed of solder slag generation, the solder in the solder bath needs to be stirred continuously, so the motor is required to drive the stirring hook to stir the solder. During the stirring process In the process, the welding slag will block the stirring hook and cause the motor to stall, and the motor will heat up rapidly during the stalling process. Generally, the motor stalling can be eliminated by switching the forward and reverse directions of the motor, but when there is a lot of welding slag , the motor can no longer eliminate the stalling through forward and reverse rotation. In this situation, the motor heats up rapidly. If no measures are taken, the motor may be burned ou...
