Abstract

PURPOSE: To provide a constant speed step drive device with a high accuracy by extracting the output of a thermal magnetic motor in a step manner through a pallel fork serving as an energy discharge system after it is accumulated in an energy accumulation system.
CONSTITUTION: A thermal magnetic motor 12 is equipped with thermo-sensitive rotor 5 having a number of thermo-sensitive magnetic pieces 1 with magnetic permeability variable whenever heated and a stator 6 made of a U-shaped yoke 7 in which a permanent magnet 10 is arranged on a piece 9 facing a piece 8 and a hole 11 for entrance of thermal energy is arranged on the piece 8 to convert thermal energy to rotaty drive force. With the actuation of the motor 12, a spring in an incense box 15 is wound up to accumulate drive energy therein. The drive energy thus accumulated in an energy accumulation system 25 composed of the motor 12 and the box 15 is extracted as a step drive force through a pallet fork 31, serving as an energy discharge system 26, composed of an espape wheel 30, an anchor 32 and a ramp 33.
