Die-cast aluminium rotors make induction motors lighter, raise the power-to-mass density and, thanks to their low moment of inertia, release greater starting torque. Because aluminium has a low melting point, die-cast rotor production is mature and low-cost, giving strong economic value; such rotors usually serve as the auxiliary drive of premium four-wheel-drive electric vehicles. The company has developed high-pressure counter-pressure feeding die-casting and centrifugal die-casting processes that increase the filling rate of the molten aluminium.

The eight-layer water-cooled flat-wire stator assembly reaches a slot fill factor of up to 70% and a peak efficiency of up to 98%, with a motor power density of 5.0 kW/kg or even higher, which makes the motor lighter and extends vehicle driving range. For the six-layer oil-cooled flat-wire stator assembly, raising the voltage from 400 V to 800 V at the same power greatly improves charging efficiency and shortens charging time, thereby improving the user experience of new energy vehicles. At the same time, the lower operating current reduces power losses, which further cuts electricity consumption over the same driving distance and thus extends vehicle range. Compared with water cooling, oil cooling benefits from the oil being non-conductive, non-magnetic and insulating, so it can contact the heat source directly, forming a safer heat exchange and improving cooling efficiency; therefore, at the same winding insulation class, an oil-cooled motor can withstand a higher winding current and deliver higher continuous power.

The product is used in automotive alternators. Slot counts range from 36 to 112 slots, voltages are mainly 12 V and 24 V, and annual capacity reaches 60 million sets. The winding process saves 30%-50% of the raw material consumption quota. A straight serrated silicon steel strip enters a high-speed automatic winding machine and is wound into a spiral by drive pins and forming rollers; the stamping die is relatively small and the required press blanking force is lower, giving clear advantages in cost and energy savings. The raw material is silicon steel sheet; adding silicon raises the resistivity and maximum permeability of the iron and reduces coercivity, core loss (iron loss) and magnetic ageing.

The core is wound in a disc configuration, which offers high material utilisation and high production efficiency; the stator assembly uses concentrated winding coils, giving a simple manufacturing process and low end losses, while the product as a whole is small, light, fast-responding, precise, quiet and highly efficient. Thanks to its distinctive technical design and performance advantages, it holds an important position in the elevator sector: at the same rating, its energy consumption is markedly lower than that of conventional motors, and its low starting current reduces grid impact and lowers electricity costs. When the elevator descends, the disc-type motor can act as a generator, converting potential energy into electricity fed back to the grid with a significant energy-saving effect. The axially flat, lightweight design saves installation space and allows flexible mounting, making it especially suitable for machine-room-less or small-machine-room elevators, where it can be embedded directly into the top of the hoistway or into the car structure, saving building space and cost.
