Title: Coreless electric motor with flat loop coils - has coils on rotor arranged to reduce coil loops overlap for increased efficiency
IPC: H01M50/40
Filed: 1975-07-14
Granted: 1982-10-14
Abstract: The coreless electric motor has a number of flat loop coils on the rotor substrate and a permanently magnetic stator consisting of two magnets. The angle between the radial sides of a loop coil is related by a specified equation to the commutator pole number and to the number of magnetic stator pole elements. The rotor is pressed against its bearing axially by a special magnetic element fixed to the rotor and interacting with the stator magnetic flux, to produce and axial force. The motor has its efficiency raised by avoiding the wasteful, large overlap between loop windings that are common in other coreless motors.

Abstract: Die Erfindung betrifft ein Verfahren zur Analyse einer Probe mit Hilfe gepulster Laserstrahlung sowie eine f r dieses Verfahren geeignete Vorrichtung. Es sind Anordnungen bekannt, bei denen nicht transparente Proben im Auflicht mit Laserlicht beschossen und die dabei entstehenden Ionen direkt in einen Massenanalysator abgesaugt werden. Eine solche Loesung hat den Nachteil, dass sowohl das Laserlicht auf die  Probe buendelnde Sammellinsensysteme als auch die Eintrittsoeffnung des Massenanalysators auf der gleichen Seite der Probe angeordnet werden muessen und damit relativ weit von dem beschossenen Ort entfernt sind. Das hat zur Folge, dass keine besonders kleinen Bereiche der Probe beschossen werden koennen, was an sich bei der Laser-mikroskopie erwuenscht waere. Zur Vermeidung dieser Nachteile wird nach der Erfindung der ausgewaehlte Bereich  der Probe zunaechst mit einem Laserschuss verdampft, das dampffoermige Probenmaterial auf die Oberflaeche eines Zwischentraegers kondensiert, und  anschliessend die auf dem Zwischentraeger befindliche Probenschicht analysiert.
