Zusammenfassung:	PURPOSE: A motor velocity controlling device is provided to reduce cost by using an operational amplifier for driving a single power and to obtain an exact output voltage to fine input current. CONSTITUTION: A motor velocity controlling device comprises an operational amplifier(3) and a microcomputer(10). The microcomputer(10) receives voltage information amplified and output by and from the operational amplifier(3) to control input current of a motor. An analog to digital converter(7) is connected to an output terminal of the operational amplifier(3), and converts an output voltage amplified by the operational amplifier(3) to provide the converted output voltage to the microcomputer(10). The operational amplifier(3) has a non-inverted input terminal for receiving a reference voltage, and a voltage divider(5) is connected to a power line for connecting the non-inverted input terminal and the reference voltage.
