Title:
ROTARY ELECTRIC MACHINE UNIT
Document Type and Number:
Japanese Patent JP2023154697
Kind Code:
A
Abstract:
To provide a rotary electric machine unit that can suppress increase in size of the rotary electric machine unit in the radial direction even when a current sensor becomes large sized or the number of the current sensors increases.SOLUTION: A rotary electric machine unit comprises: a rotary electric machine including a stator, a rotor rotating around a shaft relative to the stator, and more than one coil wound around the stator; and a power converter arranged side by side with the rotary electric machine in the axial direction along the axial center of the rotor. The power converter includes: more than one power module, each of which is electrically connected to each of the coils; more than one current sensor for detecting an output current from the power modules; and a fixing plate onto which the power modules are fixed. In the fixing plate, a cooling flow path in which a coolant flows is formed. At least part of the current sensors is arranged at a position overlapped with the cooling flow path in the axial direction.SELECTED DRAWING: Figure 5
