Axial flow electric machine i.e. motor, for vehicle, has protection case enclosing rotor and stators, and cooling circuit that is in direct contact with case for cooling stators that are placed symmetrical to rotor

摘要

The machine (100) has a protection case enclosing a rotor and stators. A cooling circuit (101) is in direct contact with the case for cooling the stators. The stators are placed symmetrical with respect to the rotors. The case is divided into two cylinder heads (3, 4) complementary to each other. Each stator is attached to the cylinder heads, and the circuit is in contact with the cylinder heads. Each cylinder head is hollowed by ducts circulating the coolant. Each duct includes a fluid inlet and a fluid outlet.
