In the bleeder circuit for hindering R8 and thermistor RS compositions, dividing point voltage is the cathode voltage of zener diode D3, by steady
The working characteristics of diode is pressed to understand that when this voltage is higher than breakdown voltage, diode D3 is breakdown, during less than breakdown voltage, two
Pole pipe D3 reversely ends, and monitoring temperature is carried out based on such principle, and since motor normal temperature is relatively low, RS partial pressures are higher at this time,
Diode D3 is in breakdown conditions, and V3 conductings, VCC voltages are normal, and with the rise of motor temperature, RS is negative temperature coefficient heat-sensitive
Resistance, resistance value is reduced as motor temperature raises, therefore its partial pressure also reduces, and therefore dividing point voltage reduces, work as temperature
