Motor controller for use in e.g. hobby-level radio controller, has control unit controlling and driving motor by drive current in response to control signal and determining duty cycle of drive current based on control signal

摘要

The controller has a detection unit detecting a drive current for a motor such as high-power direct current motor. A receiving unit wirelessly receives and demodulates a modulated control signal and outputs the demodulated signal. A control unit controls and drives the motor by the drive current in response to the control signal, and determines a duty cycle of the drive current based on the control signal. A storage unit stores a table that includes correlations between the drive current and a drive frequency of the motor.
