摘要： PROBLEM TO BE SOLVED: To provide a device for controlling and driving a sensorless DC brushless motor which is capable of reading the inducted voltage of the stator windings of the DC brushless motor without being affected by noise. SOLUTION: This drive gear is provided with a switching circuit 11, which converts a DC voltage inputted from a DC power supply VDC into a pulse width modulation(PWM) voltage, and a control device 13, which controls the switching operation of the switching circuit 11. In this case, the control device 13 consists of a voltage-detecting part 31, which detects the pulse height of a voltage in a pulse train induced on stator windings 8, a duty ratio control device 28 which controls the duty ratio of the PWM voltage applied to the motor 7, based on the detection result by the voltage-detection part 31, and a carrier frequency control device 27 which changes the carrier frequency of a carrier wave which carries the PWM voltage, in accordance with the duty ratio or the pulse width of the induced voltage.

摘要： PROBLEM TO BE SOLVED: To realize a starting device for a motor, in which the fluctuation of a soft start time due to the dispersion of parts is suppressed and the rise time of the motor can be set freely. SOLUTION: A pulse signal output from a comparison circuit A1 is converted into a triangular-waveform pulse signal by a resistor R8 and a capacitor C3, and the triangular-waveform pulse signal is inputted to a comparison circuit A2 as an input signal A2-. A reference voltage A2+ of the comparison circuit A2 is lowered gradually from 5V to 1.5V by a time-constant circuit 25. Accordingly, the gradient of the reference voltage A2+ can be changed by altering the time constant of the time-constant circuit 25, a period up to a zero-cross after falling to a low level of a pulse signal outputted from the comparison circuit A2 is varied, and the conduction timing of a TRIAC Q1 can be changed.

摘要： PROBLEM TO BE SOLVED: To provide a motor starter device which is capable of performing soft start, even when turn-on/turn-off is repeated with a short cycle, and capable of generating the rated number of revolutions. SOLUTION: A current after passing a resistor R1 is bypassed to a bypass circuit 31, the bypass current is rectified by a diode bridge DB1, and the charging of an electrolytic capacitor C1 is started. Because the charging time of a capacitor C3 is shortened as the charging has advanced, the number of revolutions of a motor 12 can be increased smoothly by gradually increasing the firing angle of a trigger diode Q2. Because the potential at each end of an electrolytic capacitor C2 charged by the bypass current is higher than the emitter potential of a transistor Q3, the transistor Q3 is turned off while the motor 12 is driven, and no bypass current flows. When a switch 14 is turned off, the electrolytic capacitor Q2 is discharged, and the transistor Q3 is turned on due to the voltage drop, and the electrolytic capacitor C1 is discharged.

摘要： PURPOSE:To smoothly start a commutator motor with a simple structure by using a positive temperature coefficient thermosensitive resistor for one of a voltage dividing resistor for specifying the charging current of an integrating capacitor for triggering a switching element. CONSTITUTION:When a switch 14 is closed, a resistor 26 has a low resistance value. Accordingly, a potential of a combined voltage point A decreases, and the voltage rise of a capacitor 30 is delayed. Thus, since the conduction rate of a thyristor 16 decreases, a current flowed to an armature 10 and a field 12 decreases. Then, as the resistance value increases due to the self-heating of the resistor 26, the potential at a point A increases, the conduction rate of a triac increases, and an armature current increases. As a result, the armature 10 is smoothly accelerated.
