ID = KI line
VD = IDR
ID in the formula - DC current required for energy braking
VD - DC voltage required for energy braking
R —— The resistance between any two of the three incoming wires of the motor
K —— coefficient, take 3.5~4. Considering the heating condition of the motor winding and making the motor have satisfactory braking effect, the coefficient K is the multiple of the excitation current; the coefficient of the transmission is high and the coefficient is large. K can be capped.
When designing or selecting a rectified power transformer, a 10% tapped transformer can be used. According to the above formula, if the motor's penetration is not large, the braking time generally does not exceed 2 seconds.
This technical specification outlines the key components and parameters involved in the energy braking system of an electric motor. The design ensures efficient and safe operation by regulating the DC current and voltage during the braking process. The use of advanced components such as the STM32L151CCU6 microcontroller and MOS power ICs enhances the system’s performance and reliability. Additionally, the inclusion of SMD aluminum electrolytic capacitors improves stability, while the mobile phone crystal ensures accurate frequency control. Proper selection of the transformer and adjustment of the coefficient K are crucial to maintaining optimal braking efficiency without overheating the motor windings.
