Blower Motor Circuit
BLOWER MOTOR CIRCUITCIRCUIT 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, B is the period of non-continuity.
The blower motor controller controls the blower motor speed.
