Motor band-type brake control circuit and servo driver

The invention discloses a motor band-type brake control circuit and a servo driver, the circuit comprises a first isolation circuit and a band-type brake driving circuit, the band-type brake driving circuit comprises a trigger circuit, a delay blocking circuit, a first resistor and a driving power supply, and the driving power supply is connected to a band-type brake voltage input end of a motor through the first resistor. The delay blocking circuit is connected with the first resistor in parallel, the trigger end of the trigger circuit is connected with the first isolation circuit to receive a trigger signal, the trigger circuit is used for triggering the delay blocking circuit to enter an on state after receiving the trigger signal, and the delay blocking circuit automatically and gradually recovers to an off state after entering the on state. Due to the fact that the trigger circuit does not directly output a driving signal to control the band-type brake mechanism, but automatically controls the voltage ap
