Patent ID: 7936138

Claim:
A motor controller for radio control, the motor controller being installed in a control target to be remotely controlled so as to control forward-moving, reverse-moving, and braking of the control target by controlling a rotation direction and a rotation speed of a motor installed in the control target based on a signal demodulated, by a receiver, from a control-data signal transmitted from a transmitter to the receiver in response to a manipulation amount of a manipulation tool of the transmitter, the manipulation tool being configured to be manipulated in at least two directions from a neutral point such that when the manipulation tool is manipulated in one direction, the control target is moved forward, and when the manipulation tool is manipulated in the other direction, the control target is braked or moved in reverse, the motor controller comprising a changeover unit configured to change a manipulation state of the manipulation tool from a brake mode to a reverse mode, wherein the changeover unit comprises: a memory unit configured to store a specific value of a brake power contained in the signal demodulated by the receiver as a changeover reference value for changing the manipulation state of the manipulation tool from the brake mode to the reverse mode; a setup unit configured to change the changeover reference value; a changeover determining unit configured to compare the brake power with the changeover reference value so as to output a changeover signal when the brake power is equal to or higher than the changeover reference value; and a control unit configured to change the manipulation state of the manipulation tool from the brake mode to the reverse mode when the manipulation tool is manipulated to the neutral point after the control unit receives the changeover signal.
