摘要： An AC synchronous motor has a permanent-magnet rotor (10) and a stator (14) and a commutator (18a, b) rotatable in union with the rotor. One or more rectifiers (22) are incorporated in the rotating commutator to interconnect the commutator sliders (18a, b). This provides simple starting means and smaller motors. It can be applied also to three-phase motors giving a unified pole conversion circuit rather than the conventional 3- stage conversion means for switching the stator poles.

摘要： A synchronous motor comprising a permanent-magnet rotor (18) and a stator (12) which, at start-up, uses rectifiers (48,52) for supplying the stator coil (10) with rectified current and a commutator (26) comprising a rotary member (22) and fixed elements (28,30,32), the rotary member (22) being axially displaceable (70) under the action of a centrifugal mechanism against a spring to disengage it from the fixed elements (28,30,32) when the rotor approaches synchronous speed and thereby connect the stator coil (10) directly with the AC supply (44).

摘要： A magnetic-pole core for an electrorotary machine, such as a DC or AC motor, has pole sections (17) which extend over the side of a coil (4) from base sections (10,11). Each pole section (17) has two sub-sections or pole pieces (20 and 21) and one of these pole pieces (20) has an extended section (22) which extends circumferentially of the coil. This structure prevents the formation of a start-up dead-point by enabling the centre of the magnetic poles of the armature (which include the pole core) to deviate circumferentially from the centre of the poles, or the mid-point between poles, of a field magnet around the armature. The core also permits uniform rotation. There may also be a third pole piece (3) between the first and second pole pieces (21,22) and all the pole pieces may be integral with the base section (10,11) from which they extend.

摘要： A 4-pole armature (12) is accommodated within a 4-pole permanent-magnet ring 10, either the ring or armature serving as the rotor. The core (16) of the armature is cross-shaped, and two opposite members of the core have windings (18) applied to them with opposite winding directions. The cross-shaped core (16) is provided on at least one, and possibly both, opposite pair of core ends with back-up core elements (20) extending in the rotational direction of the armature or in the direction opposite to the rotational direction of the ring. A commutator (22, 24, 26) or the like device for converting armature polarity is provided which alternates the direction of electric current for the armature every 90° rotation of the rotor.
