Abstract

PURPOSE: To simplify the structure of motor and improve economical operation by the construction such that two different magnetic fluxes with phases different 90° from each other are applied to a belt made of a thin metal band, and drive power is produced in the belt itself.
CONSTITUTION: In a dual-capstan tape traveling mechanism of a tape recorder, belt 14 consisting of thin ferromagnetic metal band 17 coated with rubber cover 18 is pulled around flywheels 2 and 2' fitted on capsten 1 and 1' to be driven. Two U-shaped iron cores 11 and 12 are placed across belt 14. Excitation coil 15 of iron core 11 is directly connected to the power source, and excitation coil 16 of iron core 12 is connected to the same power source via condenser 13. By this, magnetic flux ϕ2 of iron core 12 has a 90° phase lead over magnetic flux ϕ1 of iron core 11, and thereby drive power is produced in belt 14.
