Abstract
242,602. Lott, C. Nov. 7, 1924, [Convention date]. Dynamos, regulating; motors, controlling; commutators.-A dynamo - electric machine is provided with a switching arrangement whereby the armature coils may be connected to the commutator in series or in series-parallel, and the field winding is tapped so that the machine can operate on different line voltages. An insulating ring 1 rotatably mounted on a disc 6 carries contactsprings 2 each making contact with a segment of the commutator 3. One end of each armature coil is connected to a spring, and the other end to a commutator segment. The insulating ring is supported by the contact-springs and by a plate 5. The plate 5 is provided with an indicating aperture 9 through which marks 15 on the fixed disc 6 corresponding to the setting of the movable ring can be viewed. When the ring 1 is at the setting " 1,'' all the armature coils are in series, whereas for other settings the coils are connected in two, three. &c. parallel groups of series-connected coils. The brushes are wide enough to cover a number of segments equal to the maximum number of parallel groups and the number of segments on the commutator should be divisible by the ordinal number of all the connections, e.g. in a. series of four connections, the number of commutator segments should be divisible by 2, 3 & 4.
