PROBLEM TO BE SOLVED: To obtain a drive controller which can control a motor to a desired rotational speed easily, and can be configured simply and inexpensively.SOLUTION: A drive controller 1 of a motor 10 performs feedback control based on the power supply voltage Vcc. The drive controller 1 of a motor 10 includes an inverter circuit 2 and a pre-drive circuit 3 for driving the motor 10 by supplying power, and a control circuit 5 for controlling the inverter circuit 2 via the pre-drive circuit 3. The control circuit 5 detects the power supply voltage Vcc and the rotational speed of the motor 10, performs feedback control so that the motor 10 has a rotational speed preset according to the power supply voltage Vcc, and outputs a drive control signal S2 to the pre-drive circuit 3. |
