ABSTRACT:
A cylindrical field system of a low speed high torque motor is divided in an axial direction into first and second field system portions, these two field system portions are connected by a connecting member and a field magnet is disposed between the field system portions so that particularly machine work can be made before fitting of the field magnet. Accordingly, chips can be removed easily by use of a simple device.
A cylindrical field system is divided in an axial direction into first and second field system portions, these field system portions are connected by a connecting member and cylindrical magnets fixed to a flexible belt-like fixture are wound on the field system portions between them so as to produce a rotor. Accordingly, the assembling property of the motor can be improved remarkably.
