Title:
STEPPING MOTOR
Document Type and Number:
WIPO Patent Application WO/2005/124978
Kind Code:
A1
Abstract:
A small-sized stepping motor in which its rotary shaft or an output shaft disposed on the output side of its rotary shaft is improved for the purpose of achieving size reduction and motor characteristics improvement. That is, a stepping motor (1) comprises a rotor (2) having a rotary shaft (3) and a permanent magnet (4), and a stator (6) having pole teeth (5) radially opposed to the permanent magnet (4), the rotary shaft (3) being made of aluminium or aluminium alloy. Further, an output shaft (3a) installed on the output side of the rotary shaft (3) so as to project from the stator (6) is made also of aluminium or aluminium alloy.
