Correction 1984. 4.19 The claims for utility model registration and the brief description of the drawings are amended as follows. O Utility Model Registration Claim Scope A permanent magnet is attached to the rotating shaft, a stator with the basic structure shown in attached figure 1 is placed around it, and by combining this with a magnetic sensor, 360 degree rotational movement is possible. A method of manufacturing a rotary solenoid characterized by the following. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a longitudinal sectional front view of one embodiment of the present invention, and the parts indicated by numbers have already been described.The slits generate a gradient magnetic field when the stator coil is fully wound around the slits. It has a structure. Figure 2 is an explanatory diagram of the state of the permanent magnet when energized, the third section is a diagram showing the magnetic flux density of each part of the gradient magnetic field, and the fourth section is a diagram showing the state of the permanent magnet when energized.
The figure is an explanatory diagram of the operation when the permanent magnet has four poles, where A shows before energization and B shows when energization is applied. In this case, if the stator coil is wound to generate a gradient magnetic field as shown in Figure 1, the rotating part (rotating shaft and permanent magnet) can be rotated by 40° with a small amount of electric power.
You can get a powerful torque that rotates it 5 degrees.

Claims

[Scope of utility model registration request]

A rotary solenoid is characterized by having a rotor magnet with an even number of poles on the rotating shaft, and two stator coils arranged on both sides of the rotor magnet.
