Title:
BRUSHLESS MOTOR
Document Type and Number:
Japanese Patent JP2009095095
Kind Code:
A
Abstract:
To improve the response properties of a brushless motor, and also to reduce its power consumption.
An electromagnetic coil 14 is accommodated, such that it parallels its inner wall, in a casing 22 which constitutes a brushless motor 10. A shaft 28 is inserted into this casing 22, and a main magnet 20 is held via a magnet holder 66 on the shaft 28. This magnet holder 66 is hollow with its one end open, and the inner wall is apart at a specified interval from the side peripheral wall of the shaft 28. The magnet holder 66 is positioned on the shaft 28, by the cylindrical projection 71 of its wedge member 70, fitted between the inner wall of the magnet holder 66 and the side peripheral wall of the shaft 28.
