摘要： An alternating current (AC) induction machine, such as a medium voltage induction motor, includes an auxiliary electrical connection box that is incorporated in the terminal box or within separate auxiliary electrical connection boxes that are coupled to the machine's incoming power source. The box includes power conversion transformers or bridges that respectively convert the incoming AC power to other AC voltages or direct current (DC) useful for operating auxiliary devices proximal the machine. The connection box avoids the need to run separate power lines to induction machines necessary for operating auxiliary devices. Exemplary auxiliary devices include external auxiliary AC powered cooling fans for medium voltage AC motors. The auxiliary connection box may reconfigurable in the field and/or be pre-configured to provide one or more common auxiliary device output power sources

摘要： Machines and motors with multiple three-phase AC power connections. A motor includes first, second, and third windings arranged to drive a rotator shaft. A first end of each winding is connected to a respective power input of a three-phase alternating current (AC) power source and a second end of each winding is connected to a neutral. The motor includes at least one intermediate tap connected to each of the first, second, and third windings at substantially equal respective distances between the neutral and the respective power inputs. The intermediate taps together provide a three-phase AC power output at a voltage that is less than the voltage of the three-phase AC power source.

摘要： A method for manufacturing electrodynamic machine conductive coils, such as alternating current induction motor stator coils. A continuous strand of insulation coated wire is formed into a generally planar elongated closed loop having a circumference and an outer surface. Thereafter a permanent insulation layer is applied to the closed loop outer surface, preferably by spiral wrapping insulating tape about the circumference of the closed loop with a tape wrapping machine. The insulating tape has a catalytic chemical compound including at least one part of a multi-part epoxy resin. The closed loop is shaped into a rigid conductive coil by application pressure, in order to conform the coil to a desired profile. Application of the permanent insulation layer to the closed loop prior to its final shaping enables machine insulation taping over a larger portion of the coil circumference and reduces need for slower and more expensive hand taping.

摘要： Passive permanent magnet bearings (40) are incorporated into an electric machine (induction motor), in addition to a support bearing (32) on the shaft (28), being either an active magnetic, sliding or roller bearing. The magnetic field direction of the passive magnetic bearings (40) is aligned with the direction of the preload of the support bearing (32) in radial and optional axial direction to oppose "offsetting forces", like the rotor weight during starting up or stopping of the machine. The passive magnetic bearings (40) might as well absorb force on the rotor shaft (28) in radial or axial direction during normal operation, which might lead to noise or higher energy consumption.
摘要翻译：被动永磁轴承（40）除了在轴（28）上的支撑轴承（32）之外还被结合到电机（感应电动机）中，其是有源磁性，滑动或滚动轴承。被动磁轴承（40）的磁场方向与支承轴承（32）的预载方向在径向和可选的轴向方向对齐，与“偏移力”相反，就像在启动或停止时的转子重量一样机器。被动磁轴承（40）可能在正常运行期间在径向或轴向上吸收转子轴（28）上的力，这可能导致噪音或更高的能量消耗。

摘要： Permanent magnet bearings are incorporated into rotating equipment, such as induction machines, in addition to active magnetic or lubricated primary shaft support bearings. The passive magnetic bearings incorporate permanent magnets that generate directionally oriented magnetic fields of selective intensity. The magnetic field directions are aligned with a desired shaft support bearing preload direction and intensity, for example to exert axial thrust or radial preloads on the support bearings. A plurality of magnetic bearings may be oriented in opposed relationship with neutral or offsetting resultant forces. The passive magnetic force preload may be utilized to offset rotor vertical weight during induction startup or stopping cycles. Passive magnetic force preload may be applied to lubricated bearings to assure their operational stability. The passive magnetic bearings can also absorb radial or axial thrust forces imparted on the rotor shaft during induction machine operation, that may reduce machine operational noise, and energy consumption
