WebDec 29, 2024 · Braking a Motor. Two common basic methods used for braking a motor are DC injection braking and dynamic braking. We will look at both in detail, starting with electric braking. Two Basic Methods Used … WebDC injection braking provides a fast stop and can hold the motor through an applied braking force after the motor has stopped. With DC injection braking, the energy output is heat, so the braking time is usually short and quick, say no more than 2 seconds. If the time parameter for stopping was longer than that it would cause the coils to overheat.
