Geely's new EV adopts Nidec's E-Axle traction motor system
The new all-electric SUV Geometry C was announced in May this year by Geely Automobile, a subsidiary of the China-based Zhejiang Geely Holding Group that also owns Volvo Car Corp.
The Geometry C is the second model from the company's high-end EV brand Geometry and features an in-house developed proprietary battery cooling system, a heat pump air conditioning system, and lightweight vehicle body technology. It has a range of over 500 km (310 mi) and is outfitted with an automated parking system and intelligent network technology with 5G capabilities.
Nidec's E-Axle Ni150Ex that drives the Geometry C is based on the company's first mass-produced E-Axle traction motor system that entered production in April 2019. The company is using permanent magnets and a proprietary oil-cooling-based design to develop the compact motor. Combined with the next-generation inverter, the companies say it contributes significantly to the vehicle’s performance, low power consumption, and low noise and vibration of the car. By achieving a maximum power output of 150 kW (201 hp) and a maximum system torque output of 3100 N·m (2286 lb·ft) while only weighing 91 kg (200 lb) the E-Axle also contributes to reducing the weight of the Geometry C. Development and optimization of the model started in May 2019 and wrapped up in one year.
The E-Axles are characterized by being compact and lightweight as a result of their fully integrated designs that combine motors, inverters, and gears. The Ni150Ex is the latest version of the 150 kW (201 hp) model that became the first fully integrated traction motor system of its kind in the world designed by a supplier to enter mass-production in April 2019. The company has also developed four other models: Ni200Ex (200 kW or 268 hp), Ni100Ex (100 kW or 134 hp), Ni70Ex (70 kW or 93 hp), and Ni50Ex (50 kW or 67 hp). Furthermore, cars that use a front and rear dual-motor configuration can be supplied with up to 400 kW (536 hp) by combining two Nidec E-Axles. The company says it is capable of supplying traction motor systems that can power an estimated 98% of all electric passenger vehicles. Nidec has set a target of achieving 35% global market share in the EV traction motor market by 2030.
