The latest ePowertrain technology from SKF has been developed to help the manufacturers of hybrid and electric vehicles to reduce assembly and production costs.
The new technology, which will be introduced at this month’s Hannover Fair (April 13-17), will also play an important role in improving vehicle efficiency, reducing energy use, CO2 emissions and extending operating range.
The ePowertrain portfolio is built around a number of innovative and complementary products, all of which will be shown in Hannover.
The portfolio includes a unique SKF rotor positioning sensor bearing unit, designed to improve the control of permanent magnet motors. The unit integrates a low-friction bearing and intelligent sensor in a single compact and low weight assembly. Quick and simple to install on the production line, the unit offers improved motor power density and enhanced control of motor torque, reducing overall noise and vibration.
Also available is the SKF motor encoder sensor bearing unit. This provides precise encoder pulses for the accurate real-time measurement of motor speed, direction and incremental position, together with low friction, reduced noise and high-speed bearing functionality.
Other products in the ePowertrain portfolio include customized bearings for steering column applications, providing significantly reduced noise levels while maintaining existing performance characteristics, and extremely robust, low-friction and high-speed ball bearings to enhance electric motor efficiency and power density still further.
“We have developed our ePowertrain product portfolio to help HEV manufacturers improve the efficiency of vehicle sub-systems,” says Alberto Carlevaris, SKF powertrain engineering.
“This in turn reduces CO2 emissions while contributing to the vehicle driving experience through extended range and reduced noise and vibration.”
The latest SKF ePowertrain products will form part of specially constructed exhibit at the Hannover Fair and can be seen on stand B12 in Hall 22.
