This letter aims to settle the controversy about whether or not the two-reaction theory is applicable to homopolar inductor alternator (HIA). First, the prerequisite of two-reaction theory is introduced. The direct and quadrature axes of HIA are defined and the corresponding armature reaction fields are calculated respectively based on finite element method. A conclusion that two-reaction theory is applicable to HIA is made using spatial overlay analysis. © 2006 IEEE.

An electrical machine comprises a casing (1), an oil inlet hole (7), an oil passage (2), oil outlet holes (3), a stator retainer (8), a casing end cover (10), a stator iron core (5), winding coils (6), slot insulations (12) and oil-guides (4). The oil passage (2) is located inside the casing (1) and links with the oil inlet hole (7) of the casing (1) and the oil outlet holes (3) of the stator retainer (8). The oil outlet holes (3) are located above the winding coils (6) and the oil-guides (4) are located between the oil outlet holes (3) and the winding coils (6). Oil entering from the oil inlet hole (7) pours onto the winding coils (6) by the guidance of the oil-guides (4) after flowing through the oil passage (2) and flowing out of the oil outlet holes (3). The winding coils of the electrical machine can be effectively cooled and the electrical machine can achieve higher thermal durability. An oil cooling method for the electrical machine is also provided.

An AC claw-pole electric motor includes a casing, a stator connected with the casing, a rotor and two exciting parts. The rotor includes a rotor shaft (9), a center magnetic yoke (11), a first side magnetic yoke (8), a second side magnetic yoke (13), and claw poles (2, 3, 4, 5) provided on the center magnetic yoke (11), the first side magnetic yoke (8) and the second side magnetic yoke (13). The two exciting parts are respectively provided in spaces formed by the center magnetic yoke (11), the first side magnetic yoke (8), the second side magnetic yoke (13) and the claw poles (2, 3, 4, 5). The axial exciting magnetic fluxes of the two exciting parts are opposite in direction. Thus, the main magnetic flux and the magnetic energy product of the electric motor are increased, and the output and the operation efficiency of the electric motor at a low speed are improved.
