Concentric has partnered with an unnamed global Tier 1 manufacturer of fully automatic transmissions for medium and heavy-duty commercial vehicles to develop a new fully electric oil pump for use within its start/stop technology.
Production will start in 2022 and sales revenues from the new contract are estimated to be worth SEK45m (US$5.3m) during the next five years.
Start/stop technology will be offered as an option across its entire range of transmissions and will enable a reduction in CO2 emissions of up to 6% in urban applications. The new electric oil pump also uses Concentric’s wet rotor design concept that eliminates the possibility of a dynamic seal failure.
The design enables proper thermal management for the pump unit throughout its entire operation ensuring longer high-performance duty cycles.
The low noise e-pump is ultra-compact due to its high-power density and liquid cooled electronics making packaging easier. The brushless DC motor with integrated drive electronics is able to supply a high torque already from stand still. The technologies combined in the pump allow for a service life of >40,000 hours.
The drive electronics allow the power consumption to be adjusted based on system demands, reducing parasitic losses and ensuring high performance efficiency. The control and diagnostic communication with the main system is made through a CAN connection.
