Patent CZ-278409-B6 (CZ)
Title: Multi-phase electric machine
Inventor: WANLASS CRAVENS L
IPC: H02K17/12
Filed: 1980-08-14
Abstract: Prior art design characteristics result in motor flux density being maintained during normal operation at non-optimum levels. Accordingly the motor size must be substantially larger than would theoretically be necessary in an ideal motor in order to obtain the desired output horsepower. In the invention a capacitor (16) is connected in series with each stator main winding (10), (12), (14). The voltage across the capacitor (16) together with the motor input voltage periodically causes the volts-second capacity of the stator core to be exceeded causing a periodic change from high to low flux density which results in a high average flux density. Control windings (18), (20), (22) are wound on the stator core adjacent to each stator main winding (10), (12), (14) thus creating main and control winding pairs. The control windings (18), (20), (22) are wound in the opposite direction from the main windings (10), (12), (14) so that the main winding current and the control winding current of each pair is in-phase at no load and increasingly out of phase as the load increases resulting in a low flux density at low load and increased flux density at higher loads. The flux density is optimized for the particular load condition which in turn minimizes the line current for a particular load, thus minimizing the motor size required for a desired horsepower. An increase of starting and breakdown torque in the invention is achieved by placing the centers of the poles of the control windings as close as physically possible between the poles of the main windings.

The opening (12) of this guide channel (3') is covered by the supporting member (3) and the film cover (1) on the visible face which is devoid of any markings. The notches (5) of the guide-channel opening define a pocket-like opening penetration area during airbag (9') expansion. Said notches (5) form a pattern of lines consisting of a centerline and sidelines, which branch off parallel to or diagonally from the centerline. A cutting metal sheet (4) is arranged in the line pattern area between the supporting element (3) and the cover foil (1). It has cutting edges (4'), which when oriented towards the cover foil (1) coincide with the line pattern of the notches (5).
