The present application relates to a brake control method, device, circuit and storage medium. The brake control method includes: receiving the brake action signal, continuously outputting the first switch signal and maintaining the preset duration; the first switch signal is used to positively adjust the electromagnetic force generated by the electromagnet on the brake moving iron; the preset duration It is obtained according to the electromagnetic force generated by the electromagnet corresponding to the first switch signal on the brake moving iron and the performance parameters of the brake; when the preset time period ends, the second switch signal is output; the second switch signal is used to reversely adjust the electromagnetic force The electromagnetic force generated by the iron on the moving iron of the brake; according to the electromagnetic force generated by the electromagnet corresponding to the second switch signal on the moving iron of the brake and the performance parameters of the brake, the moving distance of the moving iron of the holding brake is obtained; if the moving distance is greater than the preset If the distance is set, the second switch signal is continuously output until the brake moving iron reaches the target position. The above method enables the moving iron of the brake to reach the target position at a slow or close to 0 speed, thereby reducing the noise generated by the impact.
Description
technical field [0001] The present application relates to the technical field of motor braking, in particular to a brake control method, device, circuit and storage medium. Background technique [0002] Electromagnetic brake devices are widely used in various braking systems. Electromagnetic brakes are mainly composed of electromagnets, springs, and moving iron. Generally speaking, the action of the brake can be controlled by controlling the power on and off of the electromagnet. When the electromagnet is energized, a magnetic field is generated, and the moving iron is attracted to release the moving iron and the braking device; when the electromagnet is powered off, the magnetic field disappears, and the armature is pushed to the braking device by the action of the spring. [0003] During the implementation process, the inventors found that there are at least the following problems in the traditional technology: [0004] The current traditional method has the problem of e...
