Pulse generator

摘要

A pulse generator includes a rotor assembly (2, 25) which is formed by circularly arranged magnetic poles (M), and a stator assembly (3) which is disposed coaxial with the rotor assembly (2) and is formed by stator coils (B) arranged circularly. Index angles (&thetas;) defined by the circumferential ends of the magnetic poles (M) are made unequal to each other. Pitches ( alpha ) defined by angular intervals between adjacent stator coils (B) are selected to allow the stator coils (B) to electromagnetically match the corresponding magnet poles (M) only once per revolution of the rotor assembly (3). <IMAGE>
