Abstract: [Technical Problem] An object is to provide a lubricant capable of forming a stable adsorption film on a sliding surface and stabilizing the sliding characteristics (for example, ensuring the wear resistance, etc.). [Solution to Problem] The present invention provides a lubricant represented by the following chemical structural formula. (R: a hydrocarbon group whose carbon number is 8 to 24, m and n: integers of 2 to 8) [Selected Figure] FIG.

Abstract: A permanent magnet type three-phase ac generator includes a stator having 3n (n is an integer) teeth and a tree-phase armature winding and a rotor having 4n magnetic poles each of which has a permanent magnet. The three-phase winding includes 3n coils each of which is wound around one of the teeth and connected to form three phase windings, and each coil wound around a first tooth is connected to another coil wound around another tooth that is fourth from the one of the teeth so that vectors of voltage induced in the connected coils can direct in the same direction.

Abstract: A terminal plate set has multiple terminal plates and fitting legs. Each terminal plate has a transverse bar portion and a longitudinal bar portion. If the fitting legs of the terminal plate set are press-fit into fitting through holes, terminals of the transverse bar portions are positioned on an axial end side of a rotor, and terminals of the longitudinal bar portions are positioned on the other axial end side of the rotor. The length of the transverse bar portions are adjusted so that the terminals of the transverse bar portions are positioned near coil wire leads to be connected with the terminals of the transverse bar portions.

Abstract: A permanent magnet type generator includes a rotor having 4n (n is a positive integer) permanent magnet poles disposed in a circumferential direction of the rotor to have circumferential gap between adjoining poles and a stator that has 3n teeth and coils wound around the teeth. The stator core includes a pair of core end plates and a laminate core disposed between the core end plates. Each core end plate has a circumferential width that relates to the gap distance at portions opposite the permanent magnet poles.
