Patent ID: 10224780

Abstract:
A motor includes: a rotor; an enclosure member having a front housing, a rear housing, and a stator surrounding the rotor; an output shaft-side coolant supply port on an outer circumference of the enclosure member; output shaft-side coolant supply paths configured to supply coolant from the output shaft-side coolant supply port to an output shaft side; a counter-output shaft-side coolant supply port on the outer circumference of the enclosure member; counter-output shaft-side coolant supply paths configured to supply coolant from the counter-output shaft-side supply port to a counter-output shaft side; a temperature measurement unit configured to measure a temperature of the enclosure member; switching parts configured to switch between a plurality of coolants based on the temperature of the enclosure member; and coolant flow paths that connect the output shaft-side coolant supply port and the counter-output shaft-side coolant supply port to the switching parts.
