    摘要： A motor speed, duty, and power source voltage are detected (steps S1 to S3). Referring to a load point map, a load point value is obtained (steps S4 and S5). The load point map is created with the motor speed, duty, and power source voltage taken as parameters, and is corrected in accordance with atmospheric temperature of the motor. After the load point value is obtained, the value is accumulated (step S6). The accumulated point value and a predetermined threshold value are compared with each other (step S7). If the accumulated point value exceeds the threshold value, an overloaded state is determined and the accumulated point value is stored (step S8). Thereafter, the motor is stopped.
