Abstract

883,248. Linear motors. CONSOLIDATED ELECTRODYNAMICS CORPORATION. Nov. 26, 1957 [Feb. 4, 1957], No. 36764/57. Class 35. [Also in Group XXXVI] A linear induction motor for moving the recording stylus of an oscillograph comprises a thin conducting element 36 moving between interdigitated sets of poles 22, 30 energized in phase quadrature to produce a travelling field. One set of poles 22 projects from cores 14, 16 carrying series-connected coils 24, 26 which are constantly energized from a single-phase source. The other set 30 project from cores 18, 20 carrying coils 32, 34 energized from a deviation signal to cause movement in the correct sense. The moving member 36 has tapered ends to give smooth operation, is slidably supported in tracks 38, 40, and carries a pair of contact fingers 52 which serve as a potentiometer slider connection between longitudinal resistance wires 42, 44 which are connected in the follow-up control circuit by means of which the motor is caused to reproduce an input signal (see Group XXXVI). Specification 883,247 is referred to.
