The problem of reverse braking of direct current motor!!
the motor drive circuit controlled by single chip microcomputer needs to have power reverse connection function, for example, the bridge circuit composed of 4 transistors, or the positive and negative circuit composed by relay.
Brushless DC motor is widely involved in the field is very wide, for life and production has brought a lot of help and convenience, then the knowledge is the knowledge of the braking equipment introduction, please remember firmly, for your help when in use.
when braking, the control circuit will walk into short circuit switching DC brushless motor reverse, when the motor speed is reduced to 0, to stop power supply to reverse when the motor stops rotating, the need to pay attention to the load change, from the beginning to reverse down the motor speed for the 0 time is not fixed the best, speed sensor, or need to use more complex control technology, such as adaptive control.
1, to better solve the problem, we need to know the characteristics of the walking brushless DC motor load, and the specific requirements of the use.
The above about brushless DC motor knowledge first introduced here, it is suggested that the use of the device, you need to keep in mind these knowledge, so as to help to some extent production efficiency.
