Inverter bridge hardware protection circuit, motor controller, motor and power equipment

The invention discloses an inverter bridge hardware protection circuit, a motor controller, a motor and power equipment, and the scheme comprises the steps: collecting induced electromotive force, judging whether the induced electromotive force is overvoltage or not, outputting a first signal, stopping outputting a PWM modulation signal, generating a second signal, comparing the rotating speed of the motor with a preset value, and when the rotating speed of the motor exceeds the preset value, stopping outputting the PWM modulation signal. And when the ASC logic processing module detects the first signal and/or the second signal, the ASC logic processing module outputs a third signal, when the ASC logic processing module detects the second signal and/or the third signal, ASC logic demand judgment is carried out, and when an ASC function needs to be executed, an execution instruction is output, an IGBT driving chip is configured in the ASC execution module, and the IGBT driving chip is used for rapidly realizin
