Servomotor (Only for Models with Automatic Air Conditioning)

In contrast to the previous type that detects the position by way of a potentiometer voltage, the pulse pattern type servomotor detects the relative position by way of the 2-bit ON/OFF signals. The forward and reverse revolutions of this motor are detected by way of two phases, A and B, which output four types of patterns. The air conditioning ECU counts the number of pulse patterns in order to determine the stopped position.
