The company says the eMotors will be used in the company’s second-generation 800V propulsion system platform. The vehicle model equipped with this platform is expected to start mass production in October 2023.

The 800V oil-cooled eMotors from BorgWarner are available as either motor assemblies or stator and rotor subassemblies. The company says they incorporate built-in, permanent magnet rotor and proprietary stator insulation enhancement technologies. They deliver peak efficiency of over 96% and feature patented HVH stator winding technology, the company says. In addition, the motor operates with energy efficiency and environmental friendliness with excellent noise, vibration and harshness (NVH) performance, BorgWarner says. During vehicle braking and downhill, the motor can also convert mechanical energy into electrical energy and charge the battery through the inverter.

The company separately announced it will provide “a leading Chinese OEM” with dual inverter units for the automaker’s A/A+ hybrid vehicle model slated for launch in Q2 2023. It is unknown whether BorgWarner is referring to the same company.

The product combines two inverters, a DC/DC converter, and a boost module into a single unit. By combining several power electronic technologies into one compact package, BorgWarner’s dual inverter is able to provide unrivaled functionality, driving two electric motors, powering the 12-volt electrical system, and supporting the boosted system architecture of the propulsion system, the company says.
