TE Automotive is one of the leading suppliers of sensors and modules for automotive transmission applications. The upgrade of existing transmissions to hybrid transmissions using power electric motors, mainly the synchronous type, leads to an increase of all requirements in terms of electric machines performance, which requires new technological developments.
The wide product and process portfolio of TE Automotive offers an ideal base for the development and production of such robust and reliable solutions.
The TE Automotive multi-coil resolver is designed to determine a synchronous electric motor rotor position by scanning magnetic fields. This MCR can withstand rotation speeds above 20,000 RPM and operates in a temperature range within –40 °C up to +130 °C.
Depending on the various specifications, specific adaptations may increase these values. This innovative layout also guarantees a competitive cost and makes it possible to standardize the assembling process.
As a result, it can be fitted to large diameter machines featuring numerous permanent magnets – being installed between the thermal engine and the gearbox, to separate electrical machines mounted parallel to the transmission or to another axle for instance.
TE Automotive developed the MCR technology as a product platform, capable to provide several ranges of speeds and shaft diameters in accordance with customer requirements.
