A serial of electronic oil pump(EOP) products that integrate brushless motors, oil pumps and digital controllers are successful developed, to meet the cooling and lubrication requirements of EV’s eAxle . A novel multi-profilegerotor pump is adopted, for higher efficiency and less wear; rare earth magnet is used in the high efficiency BLDC motor, and no-glue & IPM rotor technology ensures its reliability, while running and immersing in the oil; based on the 32-bit, ARMMCU, closed loop control is achieved by FOC algorithm, also innovated smart pump concept, with flow and pressure monitoring in real time, is developed in the EOP controller...
