The Electric-Hydraulic Power Steering Pump consists of a vane pump, an AC induction motor, and various connecting components. The vehicle's main power source utilizes a controller to invert DC power into the AC induction power required by the motor; once the circuit is activated, the motor begins to operate, subsequently driving the hydraulic pump to supply fluid to the steering gear cylinder, thereby satisfying the requirements of the power steering system. This product boasts numerous advantages—including an overall protection rating of IP67, extremely compact dimensions and light weight, and excellent noise performance—along with stable and reliable operational capabilities, making our Electric Pump highly popular among numerous domestic and international automotive manufacturers and customers.
