Provided is a motor controller for controlling a motor installed at an object such as an electric car operated using a transmitter. A manipulation of a manipulation tool of the transmitter is allocated for brake and reverse modes. A specific value of brake power contained in a signal demodulated by a receiver is stored in a memory unit as a changeover reference value, and a changeover determining unit compares the changeover reference value with the brake power. If the brake power is greater than the changeover reference value, the changeover determining unit transmits a changeover signal to a control unit, and if the manipulation tool is manipulated to a neutral point after the control unit receives the changeover signal, the control unit changes the state of the manipulation tool from brake mode to reverse mode. The changeover reference value can be changed by an operator using an external device.
