Recently, SAIC Roewe announced the motor information of its new plug-in hybrid intelligent network medium-sized SUV Roewe rx5 Emax. The new car will be equipped with SAIC "green core" high-power permanent magnet synchronous motor. The motor adopts the world's leading hair pin winding technology, breaking the monopoly of foreign countries on this key technology, and will set off a new wave of Rongwei in the new energy market. Compared with the traditional round enameled wire winding on the market, the hair pin winding technology of rx5 Emax motor of Rongwei makes the motor more powerful in power output, better in heat dissipation and better in NVH performance. The hair pin winding improves the traditional winding's wire arrangement, which is more regular and dense, so that the slot full rate is increased by more than 20%, and the maximum power density of the motor is increased by 20%, reaching the industry leading level. The hair pin winding technology also further optimizes the shape of the conductor. Adopting the flat type will form a larger contact area, conduct heat more effectively, and ensure the heat dissipation performance of the motor. The hair pin winding also selects a smaller notch design to reduce cogging torque ripple, mechanical noise and electromagnetic noise, which will bring a quieter cockpit atmosphere for users. The green core high-power permanent magnet synchronous motor hair pin benefits from this. The maximum comprehensive power of the rx5 Emax motor of Rongwei reaches 90kw, the maximum torque reaches 230nm, and the peak efficiency of the motor reaches 96%, which will bring more precise and explosive power. In addition, the rx5 Emax of Rongwei also has the world's leading hybrid technologies, such as 10 Speed edu second generation intelligent electric drive, dynamic oil-cooled heat management technology, intelligent energy management system, etc., to enter the new energy market with hard core quality.
