    7 - Theory of Operation Dynamic Braking The dynamic braking can be used to quickly stop the motor. The motor is used as a generator and the energy from the motor is dissipated into resistors. Dynamic Braking only works on Brush type motors. Braking Operation Sequence Figure 27: MX2 ATL Synchronous Brushtype with DB Braking Resistor.
