A generic application circuit using the ADM1024. The analog monitoring inputs are connected to the power supplies including two processor core voltage inputs. The VID inputs are connected to the processor voltage ID pins. There are two tachometer inputs from fans, and the analog output is used to control the speed of a third fan. An opto−sensor for chassis intrusion detection is connected to the CI ...

Reduction of Fan Power at High Values of Speed-Control Signal, as Result of Controller Failure The top figure shows the fit to data from a single day of normal operation. The lower figure shows data during a three-hour period when the fan speed was fixed at a single value, over a range of speed-control inputs.

Assume negligible belt losses and stretching, so power is conserved. (a) Determine the speed of the motor that maximizes its allowable power, and find this power. (b) Determine a pulley ratio that will maximize the power transfer to the fan, and find the speed and torque of the fan for this operating condition.
