| Summary: | A motor controller capable of appropriately change the drive control condition in response to variations generated in motor drive control. The receiving circuit wirelessly receives and demodulates the control signal to controllably drive the motor and then outputs the demodulated signal to the motor controller. The current detection circuit detects the drive signal for the motor. The CPU refers to a table including correlations between drive currents of the motor and drive frequencies, which are respectively stored in the memory. The CPU selects a drive frequency corresponding to a drive current detected by the current detection circuit, thus controllably driving the motor using the drive signal of the corresponding drive frequency. |
