A motor comprising: a shaft ; a rotor being provided to abut an outer circumference of the shaft ; and a stator being disposed outside of the rotor to be away from the rotor at a certain gap, the stator including: a stator core having an annular shape; teeth respectively protruding from the stator core toward the rotor in a radial direction ®; and coils (U11 to U41, V12 to V42, W11 to W41) respectively wound onto the teeth n turns including first to n-th turns, where n is an integer of 1 or greater, wherein the shaft includes a hollow part serving as a passage for refrigerant used to cool the inside of the motor characterized in that , the coils (U11 to U41, V12 to V42, W11 to W41) are each configured by winding a conductive member having a polygonal cross section onto the teeth , the polygonal cross section being orthogonal to longer direction of the shaft , and each of the coils (U11 to U41, V12 to V42, W11 to W41) includes a cut-away part on at least either a first opposing surface or a second opposing surface , the cut-away part having a shape being cut away so as to extend in the longer direction of the shaft , the first opposing surface representing an opposing surface to a side surface of a corresponding one of the teeth , and the second opposing surface representing an opposing surface to a corresponding one of the coils, the corresponding one of the coils being wound onto adjacent one of the teeth , wherein only a turn being closest to the stator core is provided with the cut-away part, and the cut-away part and at least either the first opposing surface or the second opposing surface define a space allowing the refrigerant used for cooling the coils to pass through. a shaft ; a rotor being provided to abut an outer circumference of the shaft ; and a stator being disposed outside of the rotor to be away from the rotor at a certain gap, the stator including: a stator core having an annular shape; teeth respectively protruding from the stator core toward the rotor in a radial direction ®; and coils (U11 to U41, V12 to V42, W11 to W41) respectively wound onto the teeth n turns including first to n-th turns, where n is an integer of 1 or greater, a stator core having an annular shape; teeth respectively protruding from the stator core toward the rotor in a radial direction ®; and coils (U11 to U41, V12 to V42, W11 to W41) respectively wound onto the teeth n turns including first to n-th turns, where n is an integer of 1 or greater, the shaft includes a hollow part serving as a passage for refrigerant used to cool the inside of the motor characterized in that , the coils (U11 to U41, V12 to V42, W11 to W41) are each configured by winding a conductive member having a polygonal cross section onto the teeth , the polygonal cross section being orthogonal to longer direction of the shaft , and each of the coils (U11 to U41, V12 to V42, W11 to W41) includes a cut-away part on at least either a first opposing surface or a second opposing surface , the cut-away part having a shape being cut away so as to extend in the longer direction of the shaft , the first opposing surface representing an opposing surface to a side surface of a corresponding one of the teeth , and the second opposing surface representing an opposing surface to a corresponding one of the coils, the corresponding one of the coils being wound onto adjacent one of the teeth , a turn being closest to the stator core is provided with the cut-away part, and the cut-away part and at least either the first opposing surface or the second opposing surface define a space allowing the refrigerant used for cooling the coils to pass through. <EOS>
