摘要： A rotary electrical machine (1) has at least one stator (23). The stator is provided with at least one radial channel (107) for ducting cooling air. The channel (107) extends between a first position (113) at or substantially near the rim (109) of a winding region of the stator (23) and a second position (119) at or substantially near the center (51) of the winding region. The machine (1) has cooling means (91-97) for causing cooling air to enter the radial channel (107) via the second position (119) and exit via the first position (113). The stator may have electrical windings arranged as coil sectors (183-197) disposed substantially equi-angularly in a generally circular pattern. At least some of the coil sectors are wound in a generally spiral fashion when viewed axially. A rotor (13), for the machine may have a plurality of equi-angularly spaced magnets (127), which are generally circular but with a cut-away portion, when viewed axially.

摘要： A disklike rotor is placed with air gaps between disklike stators. The disklike rotor has a sheet coil attached to its sides, on which are formed the secondary coil pattern of a rotary transformer and a resolver excitation phase pattern. A sheet coil having the secondary coil pattern of the rotary transformer is attached to the stator opposed to the secondary coil pattern on the rotor, while a sheet coil having a resolver detection phase pattern is attached to the stator opposed to the resolver excitation phase pattern on the rotor. This resolver using a sheet coil is inexpensive and small-sized, decreases angular errors, and avoids the decrease in detection voltage. The variation in amplitude of flux linkage can be limited if there is misalignment of a sheet coil.

摘要： A surface micromachined micromagnetic actuator is described, wherein rotary actuation is accomplished by a member pivotably mounted on the surface of the substrate. Angular motion of the member about the pivot point is imparted by the interaction of a magnetic tab affixed to the member, with flux generated in the gap of an electromagnetic core. Rotary motion is restricted to less than 360 degrees by using an integrally formed hinge between the pivoting member and the pivot point, rather than by a more complex bearing. By virtue of this design, a large range of motion can be achieved without requiring a true bearing to be fabricated in the device. The pivoting member is also constrained in either of two stable positions upon de-energization of the electromagnetic core, by the attachment of a bistable spring between the pivoting member and the substrate.
摘要翻译：描述了一种表面微加工微磁致动器，其中旋转致动由可枢转地安装在基板表面上的部件实现。构件围绕枢转点的角运动通过固定到构件的磁性凸片与在电磁芯的间隙中产生的磁通的相互作用来赋予。通过在枢转构件和枢转点之间使用整体形成的铰链而不是由更复杂的轴承来将旋转运动限制在小于360度。凭借这种设计，可以实现大范围的运动，而不需要在装置中制造真正的轴承。通过将双稳态弹簧连接在枢转构件和基底之间，枢转构件也在电磁芯的断电时被限制在两个稳定位置中的任一个中。

摘要： A spline is provided on a hollow shaft, and the key in the spline can couple directly a shaft to be driven of an external apparatus. Screw blocks rotational torque, thus screw is desirably located as far as possible from output shaft. Although the location is not illustrated, an anti-revolving function is desirably provided on the housing surface at the farthest place from the output shaft so that less force is required for fixedly securing the geared motor.

摘要： An energy efficient low-power integral electronically commutated fan motor and control circuit assembly mounted on a circuit board for use in refrigerators utilizing a Hall sensor to provide positional control signals for sequential energization of the windings with the Hall sensor energization being pulsed, and the motor stator windings energized only during a portion of the period, when rotational torque produced by the energization is greatest in order to reduce the power input to the assembly. Integrally molded multi-function components including the coil bobbin, ground pin, Hall sensor holder, motor bearing oil well covers, and assembly housing provide positioning, support, and securing assistance along with electrical and magnetic operative connections and positioning. A capacitively coupled bridge power supply is provided to further reduce power consumption, and the motor is protected under fault and stall conditions by a current limiting circuit and a timed retry circuit, and the rotor and stator are designed for adequate starting torque in a refrigerator. Power is supplied to the motor windings through a voltage dropping capacitor connected in series therewith.

摘要： A flat pack blower utilizes surface mounting techniques for mounting the blower electronics on a thin laminated circuit board to reduce the blower profile. To that end, the blower includes a stator, and a rotor rotatably coupled to the stator. The stator includes a coil, a pole coupled with the coil, and a laminated circuit board having blower control circuitry and pads for electrically connecting the blower control circuitry to the coil. Use of surface mounting techniques on the laminated circuit board thus eliminates the discrete electronic components and the wires connecting such components.

摘要： An actuating drive with an electric motor that has a metallic electric motor housing, a shaft, an armature, collector, brushes, and a brush holder plate, and control electronics. Electronic and electric components are connected to a printed circuit board and the printed circuit board protrudes at right angles to the shaft and into a cross section of the electric motor housing. Outside the electric motor housing, the electronic and electric components are protected by a control electronics housing. Radio interference suppression means, for example, can be disposed inside the actuating drive. The system includes a printed circuit board with a strip conductor and a contact spring that leads from the strip conductor and this contact spring protrudes into the electric motor housing, wherein a resilient free end of the spring rests against the electric motor housing producing an electrical contact.

摘要： An armature apparatus for brushless and brush type electric motors and a manufacturing method for same armature. The armature represents and improved design for electric motors having a rigid, thinwall configuration and high conductor packing density in the magnetic flux air gap that results in motors with higher torque and speed capabilities and the ability to operate at higher temperature than conventional motor designs. The armature is fabricated from pre-machined copper sheet metal parts with an electrical conductor pattern of numerous axially extending conductive bands. These precision machined sheet metal parts are cold rolled to form two work hardened cylinders, each cylinder having a complimentary pattern of electrically conductive bands creating a half-electric circuit. The two cold rolled metal cylinders are sized such that the smaller diameter inner cylinder fits inside the larger diameter outer cylinder. The surface of the inner cold rolled cylinder is over-wrapped with fiber strands, woven in several layers to provide physical spacing and electrical insulation. The fiber wrapped inner cylinder is placed inside the larger outer cylinder radially oriented to ensure that an electrical circuit is created by welding the inner and outer cylinder at the conductor tabs. The surface of this cylinder assembly is over-wrapped with fiber strands, woven in several layers and holding the two cylinders together. The entire armature coil is encapsulated in a potting material to add composite strength and electrical insulation. The result of this assembly is a freestanding, ironless core, inductive armature coil for brushless or brush type electric motors.
