Abstract
Embodiments of double-stator multi-speed motor are described. In embodiments, a motor may include a rotor. The motor may further include an inner stator having a first count of oil distributing ports opened in a surface of the inner stator. The motor may further include an outer stator having a second count of oil distributing ports opened in an inner surface of the outer stator. In some embodiments, the first count is equal to the second count. Other embodiments may be described and/or claimed.
