SKF ePowertrain portfolio reduces costs for HEVsSKF’s ePowertrain technology has been developed to help the manufacturers of hybrid and electric vehicles (HEVs) to reduce assembly and production costs. The new technology improves vehicle efficiencies, reducing energy use, CO2 emissions and extending operating range.

The ePowertrain portfolio is built around a number of innovative and complementary products. The portfolio includes the SKF Rotor Positioning Sensor Bearing Unit, which is 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. This is quick and simple to install on the production line, 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 customised bearings for steering column applications, providing significantly reduced noise level while maintaining existing performance characteristics, and very robust, low-friction and high-speed ball bearings to enhance electric motor efficiency and power density still further.

Alberto Carlevaris, Powertrain Engineering at SKF, says: “We have developed our ePowertrain product portfolio to help HEV manufacturers improve the efficiency of vehicle sub-systems. This in turn reduces CO2 emissions while contributing to the vehicle driving experience through extended range and reduced noise and vibration.”
