Beschreibung
Zusammenfassung:	A sensor signal circuit of the present invention includes a tacho generator (42) for detecting revolution speed of a motor and outputting a detection result as a sensor signal converted to a voltage, and a controller (5) for driving and controlling the motor (41) based on the sensor signal from the tacho generator (42). The sensor signal circuit further includes a voltage to current converter (43) for outputting a current in proportion to the voltage output from the tacho generator (42) as a sensor signal current, a cable (6) connecting the voltage to current converter (43) and the controller (5), and a resistor (511) for converting the current to a voltage.
