摘要： 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.

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： A method for forming rotor bar slots in an induction machine rotor includes providing a rotor body having an outer circumference, a central axial axis and a radial axis and forming opposed first and second rotor slot sidewalls having profiles diverging outwardly in opposite directions from the rotor radial axis. The opposed first and second rotor slot sidewalls are formed using a cutting tool having a first rotational axis oriented at a first angle outwardly diverging from the radial axis and with a second cutting tool having a second rotational axis oriented at a second angle outwardly diverging from the radial axis that is opposed from the first angle.
