Document Type and Number:
Japanese Patent JP3070452
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To restrain a temperature rise in a stator coil of a motor generator by partitioning/forming a cooling medium passage by/of the stator coil, a housing and partition members, connecting its cooling medium passage to a cooling medium supply source, and supplying a cooling medium to the cooling medium passage from the cooling medium supply source. SOLUTION: A housing 11 is fixed to one of an internal combustion engine or a transmission, and a fixing part 32 and a support part 35 being partition members extending from an inner peripheral wall surface of its housing 11 are brought into contact with an outer peripheral wall surface of a stator coil 51, and a cooling oil passage 53 as a cooling medium passage is partitioned by and formed of a stator coil 51, a stator core 50, the housing 11, the fixing part 32 and the support part 35. Its cooling oil passage 53 is connected to an oil pump 24 being a cooling medium supply source, and a cooling medium is supplied to the cooling oil passage 53 from the oil pump 24. Therefore, a temperature rise in the stator coil 51 of a motor generator 10 can be restrained.
