More Information
Summary:The utility model belongs to the technical field of drivers, and relates to a driver overload protection device which comprises a motor control I C, a reverser, a first high-speed optical coupler, a second high-speed optical coupler, a DC-DC circuit and a power supply protection circuit which are electrically connected. The motor control I C is respectively connected with the inverter, the first high-speed optical coupler, the second high-speed optical coupler, the DC-DC circuit and the power supply protection circuit, the second high-speed optical coupler is also connected with the inverter, and the motor control I C is used for controlling the motor of the driver overload protection device to run. The inverter is used for reversing the direction of a signal of the motor control I C, the first high-speed optical coupler is used for isolating a transmission signal and an interference signal of the motor control I C, and the second high-speed optical coupler is used for isolating a transmission signal and an i
