Excuse me, the motor has 4 interfaces, positive and negative, PWM wave intelligent temperature control, motor speed measurement, how to control it? ?

A little more detail would help others to resolve the question. What motor? Where did you get it from? Any data with it? Right now for all we know it might be an old tractor motor. If you want answers give us some data to work with...
Sorry to be so blunt, but we often get questions as vague as this one...

I think this should be moved to off Topic but at first i was thinking this was a HDD BLDC motor but now i am not to sure mind reader i am not as Yoda would say hang on i think he is !

Some applications require only torque control, other applications require stable speed, and some require extremely precise position control. These different requirements require multiple solutions.

As the temperature increases, Rs will increase, Ke and Kt will decrease, which will affect the increase in mechanical constants. Therefore, a high-performance servo motor has a temperature constant, which corresponds to the temperature rise curve of the motor itself, and dynamically modifies the electrical constant, back electromotive force constant, torque and mechanical constant of the motor.
