Dena Enhanced TM4 MOTIVE Motor and Inverter are released to provide better torque and longer driving mileage for light vehicles

On April 17, at the Shanghai International Auto Show, Dena Co., Ltd. announced the introduction of enhanced TM4 < MOTIVE} motors and power inverter for the light vehicle market.
Denner’s new TM4 MOTIVE motor and inverters adopt an integrated system with high speed permanent magnet motor, power-intensive electronic inverters and advanced controllers, which can achieve the highest standards of efficiency, reliability and performance of electric vehicles.
The product can be seamlessly integrated into the Dena Spicer gearbox and electric axle, thus providing a cost-effective, three-in-one turnkey solution for electric vehicle manufacturers.

TM4 MOTIVE motors and inverters can be used as front or rear drives of small passenger cars separately, or can be configured to run in series to meet the application requirements of higher total vehicle weight, and can be applied to commercial vehicles up to level 2.
Dena TM4 motor and inverter is the latest and most advanced combination in the series, with excellent torque and power density, longer driving mileage and a variety of applications. The combination weighs 50 kg and can be extended to 150 kW and 11,000 rpm. In addition, the integrated inverters are 33% smaller than the previous generation.
The system can now be tested by customers and is expected to be put into operation in China by 2020.
