Dc motor dynamic braking
WebThis process is called dynamic braking and such a resistor is called a dynamic braking resistor (or simply a brake resistor). To decelerate an electric motor, kinetic energy is transformed back into electrical energy. … WebSep 23, 2024 · The current produces torque which brakes the motor. This is dynamic braking, but not regenerative. However if PWM is applied to SW2 then each time it opens the collapsing magnetic field in the motor's winding inductance creates a 'back-emf' voltage which tries to keep the current going.
