Abstract
A rotary electric machine according to embodiments includes a tubular motor frame, a tubular motor cover, and a cooling fan. The motor frame includes therein a stator and a rotor. The motor cover houses the motor frame and includes a suction hole for cooling air at its counter-load side and an exhaust hole at its load side. Herein, the exhaust hole turns the exhaust direction of the cooling air to the counter-load side. The cooling fan sucks the cooling air from the suction hole into the motor cover and exhausts the cooling air from the exhaust hole to the outside of the motor cover.
