摘要： Disclosed herein is a linear d.c. motor comprising a field magnet composed of plural magnetic poles, and an armature formed by arranging armature coils along the moving direction of a moving element at a position facing the field magnet. One of the field magnet and armature is attached to the moving element, and the other is provided on a stator yoke serving as a stator. Projecting edges for linear guide, each of which projects outside and has a triangular form in cross section, are provided on both sides of the stator yoke, and guide rollers, each of which has an engaging groove in the form of a valley in its side part coming into slidable contact with the projecting edge for linear guide, are attached to the moving element. There is no possibility that the moving element is derailed because it is supported by the projecting edges of linear guide and the guide rollers. It is therefore possible to make the thrust of the moving element greater and cause it to travel at high speed.

摘要： A 1-phase energized disk-type brushless motor or fan motor comprises a single position detecting element located at a position on a printed circuit board corresponding to one of magnetically active conductor portions of one of stator coils of the stator armature. The magnetically active conductor portions include a width substantially equal to the width of each pole of the magnet rotor. A cogging generating magnetic member or plate having a width substantially equal to the pole width is located on the printed circuit board such that it is spaced by about three fourths of the pole width from one of the conductor portions of one of the stator coils so that the magnet rotor may stop with one pole thereof just opposed to the magnetic member, thereby assuring self-starting of the motor and uniform turning torque over the entire rotation of the motor.

摘要： An inexpensive brushless motor including a single position detecting element can start itself and can rotate smoothly with good efficiency and reduced noise. The motor comprises a stator core having T-shaped radial stator poles with driving coils wound on all or some of the stator poles. A field magnet having driving alternate N and S magnetic pole zones is mounted for rotation in an opposing relationship to circumferential faces of the stator poles of the stator core. A cogging generating magnetic plate is located in an opposing relationship below the field magnet and has a cutaway portion formed therein which has a suitable angular width such that the magnetic plate may generate a cogging, to move the field magnet by attraction therebetween to a position other than any dead point, and from which the field magnet can start itself. The single position-detecting element is located such that it may detect no dead point upon starting of the motor.
