STARTER WITH PLANETARY REDUCTION GEARBOX Russian patent published in 2015 - IPC F02N11/00 F02N15/00 F02N15/02 F02N15/04 F02N15/06 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, namely, to starters with planetary gearbox. Claimed starter comprises front and mid pats of the case and cover, solenoid starter switch, drive motor and overrunning clutch. Drive motor composed of carrier with gears fitted thereon and end rotors, central partial braking gear, outer and inner concentric stators and control system. This device exploits reduced rpm mode for engine warmup. Note here stators are engaged for different revolution, rotors-planet gears spin while gear-pinions displace over central gear that drives the carrier and overrunning clutch. With brake disengaged high-rpm mode follows whereat stators are thrown to aligned revolution, rotors-planet gears run-as-fixed along with carrier and central gear as a single whole. Engine started, relays and stators are disengaged.

EFFECT: reduced rpm mode at starting currents times lower as reduction gearbox gear ratio.
