Title:
DYNAMO-ELECTRIC MACHINE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/098056
Kind Code:
A1
Abstract:
This dynamo-electric machine (10) for an internal combustion engine has a rotor (21) and a stator (31) and is provided with a sensor unit (41). Said sensor unit (41) has a rotational-position sensor (43) located between magnetic poles. Said rotational-position sensor (43) detects the rotational position of the rotor (21) by detecting the magnetic flux from permanent magnets (23) on the rotor (21). The rotational-position sensor (43) protrudes from the sensor unit (41) and is accommodated inside a cover (53) located between magnetic poles. The sensor unit (41) has a leg part (61) that can be pressed against a body (13) so as to deform in the axial direction. A retainer (71) that is made from a metal plate and presses on the sensor unit (41) in the direction of said body (13) is provided. Said retainer (71) makes it possible to hold the sensor unit (41) in place stably.
