<P>PROBLEM TO BE SOLVED: To provide a motor controller and a control module of simple configuration, which is excellent in response, is used suitably in a radio control model device employing a battery as a drive source and a brushless motor as a power source, and operates the brushless motor in the state where it can be used to the utmost without interrupting power supply from the battery source when abnormal heating occurs in driving the brushless motor. <P>SOLUTION: The motor controller for radio control comprises: a circuit 14 for measuring the temperature detected by a first temperature sensor S1 arranged in a brushless motor 9; a motor drive control circuit 8 for rotary driving the brushless motor 9, based on a motor power control pulse width obtained by demodulating a remote operation signal delivered from a radio control operation unit 12; and a means 13 provided to perform variable control of the motor power control pulse width and to limit the control pulse width of the motor power control pulse according to the comparison result of the measured value of the first temperature sensor S1 by the temperature measurement circuit 14, with a preset threshold. <P>COPYRIGHT: (C)2009,JPO&INPIT |
