摘要： A permanent magnet-less, brushless synchronous system includes a stator that generates a magnetic rotating field when sourced by an alternating current. An uncluttered rotor disposed within the magnetic rotating field is spaced apart from the stator to form an air gap relative to an axis of rotation. A stationary excitation core spaced apart from the uncluttered rotor by an axial air gap and a radial air gap substantially encloses the stationary excitation core. Some permanent magnet-less, brushless synchronous systems include stator core gaps to reduce axial flux flow. Some permanent magnet-less, brushless synchronous systems include an uncluttered rotor coupled to outer laminations. The quadrature-axis inductance may be increased in some synchronous systems. Some synchronous systems convert energy such as mechanical energy into electrical energy (e.g., a generator); other synchronous systems may convert any form of energy into mechanical energy (e.g., a motor).

摘要： A method for providing additional dc inputs or outputs (49, 59) from a dc-to-ac inverter (10) for controlling motor loads (60) comprises deriving zero-sequence components (Vao, Vbo, and Vco) from the inverter (10) through additional circuit branches with power switching devices (23, 44, 46), transforming the voltage between a high voltage and a low voltage using a transformer or motor (42, 50), converting the low voltage between ac and dc using a rectifier (41, 51) or an H-bridge (61), and providing at least one low voltage dc input or output (49, 59). The transformation of the ac voltage may be either single phase or three phase. Where less than a 100% duty cycle is acceptable, a two-phase modulation of the switching signals controlling the inverter (10) reduces switching losses in the inverter (10). A plurality of circuits for carrying out the invention are also disclosed.

摘要： The accumulator of an extrusion blow molding machine is constructed so that the programming cylinder and die adjustment rod have axially aligned bores to receive a die pin retaining rod. The retaining rod holds the die pin in place by means of a lower split ring that nests inside the die pin and a lock nut combined with an upper split ring associated with the programming cylinder. When the lock nut is loosened and the upper split ring is removed, the retaining rod is moved down (while the die pin is held in place) and the lower split ring is removed. The die pin is then free to slide off the retaining rod and be removed from the accumulator head.

摘要： An accumulator head for an extrusion-blow molding machine. The accumulator head includes an annular inner sleeve member slidably positioned within an accumulator outer barrel, and a tubular inner body member received within the sleeve member. The sleeve member and body member are adapted to be slidable together within the accumulator barrel to expel collected plasticated material. The inner sleeve member includes a pair of external slots formed in the outer surface that communicate with the accumulator inlet and with respective radially extending flow passageways through the inner sleeve to convey plasticated material from the accumulator inlet into a pair of helical flow channels formed in the accumulator inner body member. The flow channels communicate with an outlet area to convey the plasticated material to an inner accumulation chamber through an annular collector channel and an annular flow passageway that provides an extruded parison having a uniform conformation without flow or separation lines. Suitable actuators are provided for together moving the inner sleeve and the inner body member to expel plasticated material, and also to selectively move an inner mandrel to provide a desired parison die outlet opening.
