摘要： An electromagnetic actuator with high performance such as high speed and high resolution is inexpensively provided with solutions to problems associated with power supply and leakage flux, which have been involved in the structure of a moving coil type and have been shortcomings of a VCM type actuator. A composite electromagnetic actuator apparatus employs the foregoing electromagnetic actuator. The electromagnetic actuator is equipped with a stationary assembly that includes two coils disposed coaxially with each other inside a hollow stator yoke composed of a soft magnetic material, and a movable assembly composed of a movable magnet unit and a movable yoke unit both disposed inside the coils with a very small clearance therefrom so as to be movable in the axial direction, wherein the movable assembly travels in the axial direction by the interaction between a magnetic field generated by the movable magnet unit and a current passing through the coils.

摘要： A bearing apparatus for use in an floppy disc drive device motor having a sleeve bearing and a thrust bearing is provided which is characterized in that there is provided a thrust bearing having such a convex portion, a projection, or a concave portion that makes the rotation shaft of the motor inclined with respect to the center axis of the sleeve bearing. Therefore, the rotation shaft ofa motor can be forcibly inclined with the rotation shaft and the sleeve bearing being kept in contact with each other. In addition, it is possible to reduce deviation in inclination of the motor rotation shaft and to ensure electric conductance between the motor rotation shaft and the motor body. These advantages are attained by a specific structure in which a projection, a convex portion, or a concave portion is provided at the thrust bearing, and therefore, the structure is simple and requires low costs.

摘要： A terminal of a motor is provided, in which a connection between a coil and an external circuit can be carried out securely and with a good workability, while saving material resources and enhancing safety relating to environmental pollution. A terminal (23) consists integrally of a magnet wire binding section (20) to connect to a magnet wire (4) of a coil (6), an external connection section (21) to connect to an external circuit and a support base section (22) to press-fit into a terminal block (19) of a bobbin (5) and hold the terminal (23), and the magnet wire (4) is plasma welded for connection through to the external connection section (21) (terminal 23). The connection of the terminal is carried out by welding (plasma welding), thus the end of the magnet wire of a motor (1) is connected without using solder containing lead. As a result, since lead is not used, material resources can be saved and safety relating to the environmental pollution can be enhanced. Since the support base section (22) press-fits into a hole of the terminal block (19) of the bobbin (5), a direction and position of the terminal (23) are settled to thereby increase the stability.

摘要： Electromagnetic conversion efficiency of an electric rotary machine is enhanced and reduction of leakage flux due to magnetic discontinuity can be realized without providing holes for positioning and fixing salient poles in a stator ring. Outer appearance and decency of the electric rotary machine as a product are also improved by not allowing lower ends of salient poles of an armature assembly to be exposed on an outer surface of the electric rotary machine. For this purpose a radial gap type electric rotary machine comprises a field magnetic pole consisting of a permanent magnet which is supported rotatably and an armature assembly consisting of a plurality of divided salient poles which oppose the field magnetic pole with a small air gap therebetween and are radially arranged with respect to a rotation axis. The armature assembly includes a first ring made of a soft magnetic member for receiving the plurality of salient poles and a second ring made of a soft magnet member for receiving the first ring.

摘要： In a device wherein a rotary shaft is provided in a pipe through which a fluid is passed, a butterfly valve is installed in the pipe, an actuator and an angle sensor are directly arranged on the outer end of the pipe of the rotary shaft, and angle control for adjusting an angle detection signal to a command value is performed to thereby adjust an amount of a fluid passing through the pipe. An actuator includes a rotor composed of a permanent magnet rotatably supported by the rotary shaft and has two magnetic poles, namely, N and S poles, and a stator composed of a winding wrapped around a cylindrical core formed of a soft magnetic member. Two phase separating members are provided on a circumference of the core so that the phase separating members are disposed to geometrically form an angle of substantially 180 degrees relative to each other, and two independent sets of coils are wound around the core at a substantially uniform density in a winding region on a core circumference that has been divided by the phase separating members.
