Title:
DC BRUSHLESS MOTOR
Document Type and Number:
WIPO Patent Application WO/2007/105314
Kind Code:
A1
Abstract:
A DC brushless motor has a rotor where a permanent magnet is fixed around a shaft
and an armature where coils are disposed on the peripheral wall of a base seat surrounding
the periphery of the rotor. The base seat has a body part surrounding the outer
periphery of the permanent magnet and also has, at both ends, base parts having
an outline smaller in diameter than the body part. The brush less motor is characterized
in that hooking parts extending over the base parts are secured to the peripheral
wall of the body part, and a gap capable of holding the coils is formed between each
base part and each hooking part. The brushless motor can be minimized in the outer
diameter, operated efficiently at high speed, and reduced in manufacturing
cost.
