Blower Motor Circuit

CIRCUIT DESCRIPTION




The blower motor is operated by signals from the A/C amplifier.
Blower motor speed signals are transmitted by changes in the Duty Ratio.

Duty Ratio
The duty ratio is the ratio of the period of continuity in one cycle.
For example if A is the period of continuity in one cycle, and B is the period of non-continuity, then.
