Resistor R
with capacitor C sets the acceleration time constant while R
2
controls the deceleration. The values of R
and R
should be at least ten
times greater than the speed set potentiometer to minimize time constant
variations with different speed settings.

The SN74LS145 is an open collector BCD to One of Ten decoder. When con-
nected as shown, input codes 0000 through 1001 steps the PWM in
increments of approximately 10% from 0 to 90% on–time. Input codes 1010
through 1111 will produce 100% on–time or full motor speed.

The rotor position sensors can be used as a tachometer. By differentiating
the positive–going edges and then integrating them over time, a voltage
proportional to speed can be generated. The error amp compares this
voltage to that of the speed set to control the PWM.

This circuit can control the speed of a cooling fan proportional to the difference
between the sensor and set temperatures. The control loop is closed as the
forced air cools the NTC thermistor. For controlled heating applications,
exchange the positions of R
1
and R
2
.
