摘要： The present invention relates to a stator used in resolvers, in which multiple slots are formed at constant intervals in the circumferential direction and have an excitation coil, a first output coil, and a second output coil are respectively wound around the multiple slots. The excitation coil is wound by a number of windings that is changed on the basis of a sinusoidal wave in accordance with the order of the multiple slots in the circumferential direction. After the first output coil is wound by a number of windings resulting from the division of the total number of windings by a constant ratio, the second output coil is wound, and then the rest of the first output coil is wound.

摘要： In a direct current motor having E-shaped interpoles, each of the E-shaped interpoles (8') includes interconnecting members (84, 85) which are made of a rigid non-magnetic material and which are tightly inserted and positively retained in gaps between a centre pole (81') and side poles (82', 83') of the E-shaped interpole. The side poles are thereby mechanically interconnected to the centre pole, so that noise generated by vibration of the side poles is greatly reduced.

摘要： A direct current motor used, for example, in a machine tool, comprising an armature (1), a plurality of main magnetic poles disposed around the armature having field windings (2) wound thereon, and a plurality of E-shaped interpoles (8) disposed at the intermediate position along the outer circumference of said armature between the adjacent main magnetic poles, each of the E-shaped interpoles consisting of a center pole (81) to which an interpole winding (10) is wound and two side poles (82, 83), and the width of the gap between the outer circumference of the armature and the end surface of each of the side poles increases from the portion of the gap which is remote from the center pole to the portion of the gap which is adjacent to the center poles.
In the DC motor according to the present invention, the linearity of the magnetic flux used for commutation is ensured in a wide range of the armature current, and, therefore, commutating characteristics of the E-shaped interpoles is improved.-

摘要： Es wird ein Reihenschlußmotor mit Kommutator und Wendepolwicklung angegeben, insbesondere für ein gebremstes Elektrowerkzeug mit Universalmotor, mit einem Stator (14), der ein Statorblechpaket (16) aufweist, das ein geschlossenes Joch bildet, mit mindestens zwei Feldwicklungen (18, 19) und mindestens einer Wendepolwicklung (20, 21), die in Nuten (26, 28, 30) des Statorblechpaketes (16) eingelegt ist. Dabei weist das Statorblechpaket (16) im Bereich der axialen Enden (40) der mindestens einen Wendepolwicklung (20, 21) quer zur Axialrichtung (50) des Stators (14) verlaufende Aussparungen (42) zur Aufnahme der Wicklungsenden (40) der mindestens einen Wendepolwicklung (20, 21) auf, so daß die Wendepolwicklung (20, 21) bündig im Statorblechpaket (16) aufgenommen werden kann und somit die axiale Baugröße des Stators (14) bei gleichbleibender Leistung verkürzt wird.

摘要： The invention relates to an inverse speed motor, especially a universal motor, with a braking device and a stator having a field winding and a rotating armature powered via a commutator and brushes and a suitable circuit for switching the field winding to braking mode and a braking device inducing an additional magnetic field during braking. The inverse speed motor is to be constructed in such a way that, when it is switched from motor to generator or braking mode, the braking process is simply triggered via self-excitation. To this end, to the set of pole shoes (12) of the stator are allocated means for inducing a magnetic field, preferably at least one additional coil (20), and at least one pole arc (16) of at least one pole shoe has a groove (18) or a pair thereof and the additional coil (20) is arranged in the groove (18) or pair or grooves.

摘要： A direct current motor used, for example, in a machine tool, comprising an armature (1), n main magnetic poles (3,4) disposed around the armature, each of the main magnetic poles consisting of a pole core (33,43) on which a field winding (5,6) is provided and a pole piece (34,44) extending along the outer circumference of the armature, and n/2 E-shaped interpoles (8) disposed at the intermediate position along the outer circumference of the armature between the adjacent main magnetic poles, and at the central axls (0) of the armature, the angle (a) spanning from the direct axis (B), which is electrically perpendicular to the interpole axis (A), to an end portion (31) of a pole piece (34,44) of a main magnetic pole (3, 4) is unequal to that (ß) from the direct axis (B) to the other end portion (32) of the pole piece (34, 44) of the main magnetic pole.
Since the number of the E-shaped interpoles is decreased by half, the direct current motor according to the present invention has simple structure and high torque, and the heat generated by the interpoles is relatively decreased.-
