AIR CONDITIONING SYSTEM


  1. CONSTRUCTION


    1. In contrast to the previous type of servo motor that detects the position by way of potentiometer voltage, the pulse pattern type servo motor detects the relative position by way of 2-bit on/off signals.

    2. The forward and reverse revolutions of this type of servo motor are detected by way of 2 phases, A and B, which output 4 types of patterns. The air conditioning amplifier assembly counts the number of pulse patterns in order to determine the stopped position.
