Title: Single-phase brushless motor
Inventor: TAKASHIMA YOSHIHARU
IPC: H02P6/06
Filed: 1999-04-01
Abstract: PROBLEM TO BE SOLVED: To obtain a high output even in the case of rotation at high speed and correspond to rotation at high speed while excellently keeping rotation efficiency even in the case of rotation at low speed. SOLUTION: The on-off of electric conduction to an armature winding 3 is determined by timing when the pole boundary 2a of a rotor magnet 2 passes through Hall elements 7, 8, the quantity of the rotor magnet 2 rotated (the quantity of displacement). Consequently, the on-off ratio of electric conduction to the armature winding 3 can be kept approximately constant regardless of the rotational speed of the motor. Accordingly, since a ratio with time of conduction-off is not lengthened even in the case of rotation at high speed, a high output can be obtained, and the motor can be turned at high speed. Since electric conduction is turned off surely when the rotor magnet 2 is turned up to a fixed position even in the case of rotation at low speed, the electric conduction of the generation of stop torque is eliminated, and the driving (rotational) efficiency of the motor can be improved.
