Abstract
PURPOSE: To achieve good characteristics even when a high output is developed, by moving a magnet in accordance with the operation of a pedal, and detecting the mevement of the magnet by a Hall element to control the motor speed, wherein the surface of the permanent magnet facing the Hall element is curved.
CONSTITUTION: When a pedal 7 is pushed down, a permanent magnet 10 is moved via a connecting rod 9, and the movement of the magnet 10 is detected by a Hall element 11 to control the motor speed. The permanent magnet 10 is formed such that it has a plane bottom surface and a curved surface A facing the Hall element 11, and it is magnetized to have S, N poles as shown in the figure. The desired characteristcs can be obtained by selecting the lengths of the curved surface A and the surfaces C, D of the permanent magnet.
