ENERGY RECYCLING IN DC MOTOR DRIVES
When decelerating a moving mass in a permanent magnet motor drive, energy stored in the mechanical system may be returned through the motor driver to the power source. If this energy is not properly accounted for, it can cause damage to the motor driver or the rest of the system by causing an increase in the power supply voltage. In this article, we will look at ways to dissipate this energy safe...
