Embodiment
[0015] This embodiment describes a disc brake braking circuit that can eliminate the power-off residual magnetism delay, including a power supply circuit, a rectification voltage divider circuit, an electromagnetic starting circuit, a demagnetization circuit and a brake. The output voltage of the power supply circuit is passed through The rectifying and dividing circuit (in this embodiment, half-wave rectifying and dividing circuit is used to obtain the required voltage in the high-voltage output part, and the required voltage is obtained in the low-voltage part by using transformer transformation combined with full-wave rectification) and transformer transformation Output two DC voltages after rectification, the two DC voltages are sent to the electromagnetic starting circuit, the high-voltage output of the electromagnetic starting circuit is connected to the brake to start and open the brake, and the low-voltage output is used to maintain the opening of the starter state, whe...
