An electric motor may include: a stator; a rotor; and a tubular sleeve. The stator may have a stator cavity with an axis extending in a longitudinal direction. The stator cavity may have a stator inlet for receiving a fluid and a stator outlet for discharging the fluid. The rotor may be arranged inside the stator cavity and be rotatable around the axis. The tubular sleeve may be arranged between the stator and the rotor, coaxial with the axis, and attached to the stator through attachment members. The tubular sleeve may be spaced from the stator by a first tubular gap, and from the rotor by a second tubular gap. The first tubular gap may extend along the longitudinal direction between a first gap inlet and a first gap outlet. The second tubular gap may extend along the longitudinal direction between a second gap inlet and a second gap outlet.

Electric motors

An induction motor may include a housing, a stator, a rotor, and/or cooling fins on an outside surface of the housing. The rotor may include inner air ducts configured to allow passage of airflow therethrough. The motor may include outer air ducts in fluid communication with the inner air ducts to form an air-circulation circuit. The outer air ducts may be arranged radially outside the cooling fins.

Induction motors

A magnetic wedge comprises a first element of magnetic material extending longitudinally along a first direction and second element of non-magnetic material coupled to the first element and having at least one skew portion relative to the longitudinal extension direction of the wedge.
