摘要： PROBLEM TO BE SOLVED: To provide a controller for fan motor which can prevent an overcurrent by stabilizing a current at start. SOLUTION: This controller is equipped with an inverter part 2 which drives a fan motor 4, two position detecting sensors 43 and 44 which detect the rotational positions of the rotor 42 of the fan motor 4, and a control unit 3 which controls the output of the inverter part 2. The start control unit 33a of the above controller 3 finishes synchronous operation and performs the position detected operation based on the position signals Hu and Hv detected by the position detecting sensors 43 and 44, when the present revolution obtained from the position signals Hu and Hv detected by the position sensors 43 and 44 in synchronous operation where the inverter part 2 outputs an exciting pattern for start and the revolution of the output of the inverter part 2 are almost the same, at the start of the fan motor 4. The phase corrector 33b of the above control unit 3 corrects the phase of the output voltage of the inverter part 2, based on the rise and fall of the positional signals Hu and Hv detected by the positional sensors 43 and 44 in synchronous operation.

摘要： PROBLEM TO BE SOLVED: To provide a fan motor controller for suppressing the generation of an abnormal noise while protecting a power element by suppressing repetitive interruption and restoration of a signal to be outputted to a fan motor, and preventing reduction of an operable area of the fan motor. SOLUTION: In the fan motor controller, when an overcurrent of a brushless DC motor is detected, a signal to be outputted to the brushless DC motor is interrupted. After that, a modulation rate upper-limit value is set so that the modulation rate of a signal to be outputted to the brushless DC motor may be limited at a modulation rate within a range smaller than the modulation rate in detecting overcurrent (S52, S53). If the modulation rate upper-limit value is lower than the preset lower-limit value (No in S54), the lower-limit value is set as the modulation rate upper-limit value (S55).

解决方案：在风扇电机控制器中，当检测到无刷直流电动机的过电流时，将输出到无刷直流电动机的信号中断。之后，设定调制率上限值，使得输出到无刷直流电动机的信号的调制率可以在检测过电流的调制率以下的调制率下被限制（S52，S53 ）。如果调制率上限值低于预设下限值（S54中为“否”），则下限值被设定为调制率上限值（S55）。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a motor drive control device that easily controls drive of a three-phase brushless motor without separately requiring a control part having a complicated algorithm even when using two hall elements, and to provide a motor drive control system. SOLUTION: The motor drive control device 1 controls drive of a brushless motor 51 that includes a stator 52 having a three-phase drive coil and a rotor 53 having a plurality of magnetic poles. The device is provided with the hall elements 2u, 2v, a driving-signal determination part 7, and an output circuit 8. The hall elements 2u, 2v are provided at respective positions separated from each other by 120 degrees at an electrical angle so as to output position detection signals Hu, Hv showing the position of the rotor 53 with respect to the stator 52. The driving-signal determination part 7 determines driving signals SU, SV, and SW for driving the three-phase drive coil on the basis of the position detection signals Hu, Hv. The output circuit 8 generates the driving signals SU, SV, and SW determined by the driving-signal determination part 7 so as to output them to the three-phase drive coil.
