Abstract

PURPOSE:To control deformation after pressing and to obtain a stator which can select rotary direction at the time of incorparating the stator by a method wherein the shape of the stator except that of a magnetic pole hole is formed in bilateral symmetry. CONSTITUTION:A stator 5 is obtained from a hoop material consisting of a high- permeability magnetic substance such as permalloy or the like by punching the stator 5 having a magnetic pole hole 6 (a hole for accommodating a rotor) and holes for fixing screws. Where, the shape of the stator 5 except the magnetic hole 6 is formed in bilateral symmetry viewing from the center of the magnetic hole 6 and the magnetic hole 6 is provided with a pair of notches 7 for deciding the rotary direction of the rotor. This can select the rotary direction of the rotor by selecting the face and reverse at the time of incorporating the stator 5 and the symmetrical shape of the stator 5 can mostly control deformation after punching processing.

The stator 1 is press-cut from a hoop material made of high permeability magnetic material such as permalloy, and has a rotor storage hole near its center so as to be magnetically coupled to a rotor made of permanent magnets through an air gap. 2 is a provision. Furthermore, a pair of notches 3 are provided in the rotor storage hole 2 in order to determine the direction of rotation of the rotor when the rotor is stored and to operate it as a motor. Furthermore, a pair of screw holes 4 are provided for fixing when the stator is assembled as a fic motor.

However, with this method, since the left and right shapes of the stator 1 seen from the center of the rotor housing hole 2 are asymmetrical, the inner circumference of the rotor housing hole 2 is likely to be deformed after the press punching process, and the result may not be as designed. The motor performance of the stator is often unreliable, especially in the case of modern wristwatches, where the step and motors used are required to operate stably at low power. High precision is essential.

Furthermore, recently there has been a strong demand to reduce the cost of the steps and motors used in watches, and although the steps, motor rotors and coil blocks are relatively versatile and can be easily used in other models of watches, On the other hand, in the case of a stator, the rotating direction of the rotor is determined by the notch 3, as shown in Fig. Since the number of gear trains is different between the 3-needle and 3-needle models, the position of the notch 3 shown in Fig.
Since the stators must be set at different positions, it is necessary to design a stator for each model, making it difficult to use a stator for multiple uses.
