What is the open source of motors?

When the temperature of the permanent magnet motor rises, the magnet will demagnetize, so the power will drop and the power will be insufficient. In the initial stage, the driving force of the motor is more than enough, but when the temperature rise and demagnetization occurs, the motor can only drive the car or it can no longer drive the car. Running. At this time, the direct current, which has not limited current, overwhelms the motor, the temperature of the motor winding rises sharply, and the arc of the carbon brush contact point ignites and burns.

Increasing the heat dissipation power of the motor can reduce the accumulation of heat in the motor, thereby reducing the temperature of the motor.

The circuit board can be removed to improve the air flow conditions on the motor surface. Then add a certain specification of heat dissipation metal sheet on the surface of the motor, so that the flowing air is blown on the radiator to enhance heat dissipation during operation.

Of course, if you use the following type of heat sink with forced air cooling, the fan is expensive. I have tested the 540 motor with 12v load and will not burn. 1. The output port of the motor drive board is connected in parallel with one 0.1uf nearby, and the two output terminals of the motor are respectively connected to the ground through two 0.1uf. At the same time, buy the pin-type 104, and polish the motor shell. There are also two terminals in parallel, and each terminal and the motor shell are combined. In this way, you will find that the sparks of the motor will be very small, which means that most of the motor burns are not handled properly by the circuit; second, soft start, no matter if the program is written, there are two principles in the final output, one or two times The MAX value of the speed change. Excessive acceleration will pull down the voltage, and excessive deceleration will rush the high voltage. If a bad software output does not consider the physical characteristics of the motor, it will burn the motor at light, and damage the entire circuit.
