Blower Motor Circuit
Blower Motor CircuitDESCRIPTION
The blower motor is operated by signals from the air conditioning 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, A is the period of continuity in one cycle, and B is the period of non-continuity.
The blower motor controller controls the blower motor speed.
The blower motor controller reads the signal from the air conditioning amplifier and controls rotation and speed.
