To extend the lifespan of your board, the idea is clear: provide sufficient heat dissipation margin for power devices, choose long-life electrolytic capacitors with specifications of 105 ° C or even higher, perform robust filtering and transient suppression at the power and motor ports (such as adding varistors

Firstly, regarding reliability. In modern well-designed controllers, the protection function is usually quite reliable, and its core lies in the "dual protection mechanism". The first line of defense is real-time protection at the hardware level, which is like a conditioned reflex that can respond to fatal faults such as overcurrent within microsec

But hardware matching is just the beginning, whether it can "communicate smoothly" is the key. If the motor needs to receive precise Hall signals for commutation, and there is a deviation in the output timing of the controller, the motor will behave like a novice who cannot understand instructions, with stiff movements and annoying vibration sounds

First of all, the three most important core indicators are: torque constant (Kt), back electromotive force constant (Ke), and motor efficiency curve. You, the smart one, must know that Kt and Ke should have equal values in an ideal state. If the two values given by the supplier differ greatly, um... It is suggested that you remain vigilant. This is
