Abstract
A sensor signal circuit of the present invention includes a tacho generator () for detecting revolution speed of a motor and outing a detection result as a sensor signal converted to a voltage, and a controller () for driving and controlling the motor () based on the sensor signal from the tacho generator (). The sensor signal circuit further includes a voltage to current converter () for outputting a current in proportion to the voltage output from the tacho generator () as a sensor signal current, a cable () connecting the voltage to current converter () and the controller (), and a resistor () for converting the current to a voltage.
