Blower Motor Circuit

BLOWER MOTOR CIRCUIT

CIRCUIT DESCRIPTION

The blower motor is operated by signals from the A/C amplifier assembly. 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.
