摘要： An intravascular blood pump designed to be advanced through the blood vessel system of the patient, comprises a housing (15) accommodating an electric motor (12), the proximal end of the housing (15) being connected to a catheter (23) and the distal end thereof carrying a pump (11). The electric motor (12) includes a stator winding (17) forming a load-bearing component of the housing (15). The stator winding (17) is embedded in a matrix made of synthetic resin. The housing (15) is of an ironless design without any magnetic reflux device. The motor is operated with a rotational speed of about 50,000 upm. The magnetic stray field generated with such high frequencies does not disturb the cardiac rhythm of the patient. The motor can be given a compact size and thus has a high mechanical output power.

The power supply system includes at least one drive machine and at least one generator driven thereby.

The bundle conductors of the winding are made from insulated thin cooper wires that are disposed in an annular gap between a rotor and a laminated iron yoke, and the air gap three phase winding is reinforced by a plastic structure and/or embedded in or impregnated with resin and to which a pertaining cooling device is connected by which the heat produced in the cooling device is dissipated.

摘要： Disclosed is a Segmented Coil Array (“SCA”) for use in rotary electromotive devices, such as motors and generators, which employ multiple coils operating within an axial gap magnetic structure. Individual conductor coils have offset circumferentially extending portions so as to allow interlocking of adjacent coils radially extending portions to form a circular array in which all of the coils' working conductors, which are those in the axial magnetic field, can be oriented in the same plane. This construction allows minimum magnet gap spacing, thus, maximizing the available magnetic flux. The resulting SCA may easily be commuted as a three-phase motor, actuator, or generator. The invention also provides a structure whereby multiple coil arrays and associated magnetic rotors may be alternately stacked in layers so as to further increase the total coil working area within a motor or generator of a given diameter.

摘要： A system and method for reducing the cost of producing a brushless DC motor is presented. The brushless DC motor provides higher power density and efficiency with an increased tool run time. The brushless DC motor includes a rotor assembly that has an unmagnetized permanent magnet affixed to a shaft. The permanent magnet remains unmagnetized until the motor is partially assembled. A plurality of coils for producing a magnetic field are wound about the rotor assembly. The coils include end turns that enclose the rotor assembly such that the rotor assembly is not removable. Since the windings are wound with the rotor assembly already enclosed, the windings do not require large end coils to allow subsequent insertion of the rotor. Minimizing the end coils reduces the length of wire required per turn, thereby reducing the resistance of the winding. Also, since the permanent magnet is unmagnetized when the coils are wound around the rotor assembly the winding process is simplified by not coupling energy into the wire which would influence the winder operation. The wound assembly is inserted into a stator stack comprised of magnetic material that provides a magnetic flux return path for the magnetic flux generated by the permanent magnet. Using an unmagnetized permanent magnet facilitates easy insertion of the wound assembly into the stator stack, reduces the accumulation of magnetic debris during the manufacturing process, and permits the motor assembly to be sealed prior to magnetizing the permanent magnet.
摘要翻译：提出了一种用于降低无刷直流电动机生产成本的系统和方法。无刷直流电机通过增加刀具运行时间提供更高的功率密度和效率。无刷直流电动机包括具有固定在轴上的非磁化永磁体的转子组件。永久磁铁保持非磁化，直到电机部分组装。用于产生磁场的多个线圈缠绕在转子组件上。线圈包括围绕转子组件的端匝，使得转子组件不可拆卸。由于绕组与已经封闭的转子组件缠绕，绕组不需要大的端部线圈以允许转子的后续插入。使端部线圈最小化可减少每圈所需的导线长度，从而降低绕组的电阻。另外，由于当线圈缠绕在转子组件上时永磁体不被磁化，所以通过不将能量耦合到导线中来简化卷绕过程，这将影响绕线器的操作。卷绕组件插入由磁性材料构成的定子堆叠中，该磁性材料为由永磁体产生的磁通提供磁通返回路径。使用非磁化的永久磁铁有助于将卷绕组件容易地插入定子堆叠中，减少制造过程中的磁性碎屑积聚，并且允许电动机组件在磁化永磁体之前被密封。

摘要： Some of linear motors which constitute an exposure apparatus have coils each obtained by winding a copper foil wire as a foil-like conductor having an insulating layer around a core member in a multilayered structure. The coil is fixed to a positioning portion serving as the coil fixing portion of the linear motor by using the core member. The core member is formed from the same insulating material with low thermal conductivity as that of the positioning portion of a linear motor housing or a material with almost the same linear expansion coefficient.

摘要： An improved airgap armature for use in brushless rotary electrical machines is constructed with multiple phase windings comprised of wires that are wound onto and bonded to a supporting form constructed from nonmagnetic and electrically nonconductive material. The form has two ends, each with features for holding end turns of the multiple phase windings. The multiple phase windings have active lengths and end turns, with the active lengths being located on one side of the form and the end turns located on the opposite side of the form. The active lengths, which are located in the armature airgap of the electrical machine, lie flat against the form for minimal thickness, and the airgap armature can achieve maximum winding density. The form provides an easy method for winding as well as increased structural integrity in the final armature to enable it to transfer torque between the rotor and stationary housing.
