Document Type and Number:
Japanese Patent JP2738675
Kind Code:
B2
Abstract:
PURPOSE:To make a constant speed running device in small size, at a low cost and with high precision by constructing part or the whole of a control circuit for a control motor in such a way as hybrid-IC'ed, and installing it at the housing outer surface of said control motor. CONSTITUTION:With this constant speed running device, a carburettor throttle valve is controlled through a transmitting means by the use of a control motor (step-motor), and thus an engine is run at a constant speed. The step motor consists of a rear and a front housing 11, 12, and a middle housing 13 mounted between the former mentioned in such a way as consolidated in a single piece. At the bore of this middle housing 13, a stator core 14 is installed, and armatures 17a, 17b and a permanent magnet 18 are mounted on a rotary shaft 16 supported at the housings 11, 12 rotatably. Here part of a control circuit for the motor is constructed hybrid-IC'ed. This hybrid-IC'ed portion is fitted at the outer surface of the rear housing 11.
