International Classification:
H02K 1/00
US Classification:
310178, 310180
Abstract:
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.

H02K 15/00
US Classification:
29596
Abstract:
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.

International Classification:
G06F 17/50
US Classification:
716136
Abstract:
A computer implemented method for evaluating quality control data of a product manufactured by a partially automated manufacturing process. In the method, a database is generated which includes design specifications for the product. Manufacturing data generated from inspection of the product at each stage of the partially automated process is then received. The manufacturing data is then compared with the design specifications to determine whether the manufacturing data meets the design specifications. In one embodiment, the product is an induction coil used in electric motors.
System And Method For Increasing Airflow In Electric Machines
An air-cooled electric machine, such as an alternating current motor, having a housing containing a rotating shaft and a housing airflow cooling path has cooling vents on the housing periphery. An external cooling system having a duct enclosure is coupled to the housing exterior, and defines a duct airflow cooling path that is in communication with the housing airflow cooling vent and housing airflow cooling path. A duct fan within the duct enclosure external the housing is coupled to and driven by the shaft. The duct fan circulates air at above ambient pressure into the housing airflow cooling path.
Induction Machine Power Connection Box Including Power Supply For Auxiliary Devices Including Auxiliary Cooling Fans
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.
Passive Magnetic Bearings For Rotating Equipment Including Induction Machines
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.
A rotor bar slot having diverging sidewall profiles that are analogous to a dovetail cut is formed within an induction machine rotor body by cutting into the rotor body with a cutting head. The rotor slot diverging sidewall profile enables the rotor body to constrain a rotor bar inserted into the slot, against centrifugal forces imparted on the rotor bar during the induction machine operation.
