Motors with unwound iron armatures; alternating-current commutator machines. -In a single-phase synchronous motor the stator poles are provided with teeth having the same angulai pitch as the teeth of the rotor, so arranged that the stator teeth coincide with the corresponding rotor teeth, both sets of teeth being permeated by an alternating flux. The rotor may be unwound or may have a commutator winding, the brushes of which may be (i) connected to the A.C. supply permanently or during starting, (ii) short-circuited (if permanently, through a resistance), or (iii) rocked from the neutral position and short-circuited for starting. In another arrangement the commutator may have one pair of brushes permanently connected to the A.C. mains and another pair which is rocked from the neutral position and short-circuited for starting. As an alternative to the commutator winding, the motor may be started by any of the usual means, the mass of the rotor being preferably increased to increase its rotational energy. In the form shown, the two-pole stator has an exciting winding E and the rotor has a commutator winding and brushes B. The stator poles are divided into sub-poles and the rotor has corresponding teeth. The rotor should have sufficient inertia to overcome when starting the dead points which are caused bv the constructional form of the motor. The windings on the stator and rotor, as above described, may be interchanged. The motor may be used to give very low speeds as required for driving clocks, &c. Specification 25385/10 is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification of the winding arrangement to allow the motor to operate on a polyphase supply.
