摘要： An angle detector 25 sets a q-axis command current to a first magnetic pole detecting current Iq_p1 and a second magnetic pole detecting current Iq13p2, and performs a magnetic pole detecting process to calculate a first magnetic pole reference value A1 and a second magnetic pole reference value A2 (t2-t3, t4 -t5), and detect the orientation of the magnetic poles of a rotor 2 of a motor 1 based on the sign of the difference &Dgr;A (=A1-A2) between the first magnetic pole reference value Al and the second magnetic pole reference value A2. The angle detector 25 effects a proportional process only on the difference between the q-axis command current and a detected q-axis current and the difference between a d-axis command current and a detected d-axis current to calculate a current difference (t2-t5) under current feedback control when the magnetic pole detecting process is carried out, and effects a proportional plus integral process on the above differences to calculate a current difference (t0-t2, t5-) under current feedback control when the magnetic pole detecting process is not carried out.

摘要： PWM controlling means (4) for inputting PWM signals corresponding to PWM target values to electric power supplier (3) in order to servo-controlling DC motor (2) comprises synchronizing control part (41), PWM computing part (50), selecting part of PWM target value (45) and PWM commanding part (46). The synchronizing control part (41) instructs the commencement of the PWM computation, selection of PWM target value and PWM command allotted to some of the infinitesimal intervals obtained by dividing processing term, on which PWM signals regulating the electric power supplied to the motor (2) are allotted, into n equal parts, and terminates one cycle for a series of the process and/or computation predetermined within one processing term. PWM target values corresponding to plural control target values (DP0, DV0, DT0) are computed in parallel so that the servo-control of motor can be operated in quick response to the change of control mode.

摘要： A disk drive apparatus reproduces a signal from a disk and/or records an signal on the disk. A position detecting part produces a position signal in response to a rotation of a rotor. An activation operation block controls active operation of first and second power amplifying parts in response to the position signal. A signal producing part produces a slope signal which repeats a slope waveform a plural times during one period of the position signal. The shaping part produces first and second activation control signals which responds with the slope signal. The activation operation block controls the first and second power amplifying parts responding with the first and second activation control signals. Therefore, an excellent disk drive apparatus with reduced acoustic noise and reduced vibration can be realized by using only one position signal of one position sensor.

摘要： A motor control system creates a rounding effect on square wave phase currents which results in reduced acoustic noise. The control system includes a voltage source for providing a DC bus current, and an inverter. The inverter has a switching circuit for regulating the DC bus current to a fixed level. The switching circuit also forces consecutive phases of the motor to share the bus current at commutation. Forcing consecutive phases of the motor to share a desired amount of the DC bus current creates a “rounding” effect on the phase currents, which results in reduced acoustic noise. The preferred inverter has a plurality of transistors, and a control module. The control module selectively engages the transistors such that each phase of the motor has a phase turn-on point that occurs before a phase turn-off point of a preceding phase. The control module also pulse width modulates the transistors such that the DC bus current is regulated to the fixed level. The result is a motor control system and method that is less expensive and produces less acoustic noise than conventional noise.

摘要： An electronically commutatable motor, in particular for a fluid pump, includes excitation windings that may be connected to and disconnected from a DC supply voltage via semiconductor switches that are controlled by control signals of a commutation device. Additional closed- and/or open-loop control of the output of the motor, is obtained with a temperature protection system in that the control signals of the commutation device are clocked by pulse width modulatable output signals of a PWM generator and in that the pulse width ratio of the output signals of the PWM generator may additionally be modified as a function of the output signal of the temperature sensor.

摘要： An actuator (12) has a movable member (20), and has a coil (26) which can be controlled to urge the member to move. In a particular mode of operation, a driver circuit (70) is periodically uncoupled from the coil so that the current through the coil goes to zero, after which the back-emf voltage of the coil is applied to a capacitor (94). Then, the driver circuit is recoupled to the coil, and the voltage held by the capacitor is used to effect feedback control of the driver circuit for the coil.

摘要： In controlling a motor in a device which drives a mechanism using the motor as a power source, pre-driving of giving a predetermined driving parameter to the motor and driving the mechanism is executed. During the pre-driving, movement of the mechanism is monitored, and a command value to the motor, which is necessary for starting the mechanism, is obtained. Driving of the motor is controlled using feedback using the command value as the initial value of the driving parameter. High-speed accurate position control can be achieved independently of the individual difference in an object to be controlled and the frictional force of the mechanical portion or the difference in use environment.

摘要： The specification describes a method and a detection module for determining the rotor position of an electromotor having a plurality of motor phase windings, in which, for determining the rotor position, the polarity of at least one motor phase voltages, which is induced in at least one first motor phase winding, is determined as at least one first polarity value, through comparison to a reference value. The reference value is, for example, a real or simulated star-point voltage. In one embodiment of the invention, the determination of the at least one first polarity value is synchronized to switch-on time point for supplying current to the at least one first or second motor phase winding, and in one specific embodiment, at least one first polarity value is determined after a preestablished delay, which follows the switch-on time point.

摘要： An automatically controlled DC power supply output circuit includes an isolation diode connected in series between the power supply and the load, a terminal voltage detection circuit connected in parallel between the power supply and the load on the load side of the isolation diode, and a shunt resistor connected in parallel between the power supply and load on the power supply side of the isolation diode. A control element such as a switch or variable impedance is connected in series with the shunt resistor to cause the shunt resistor to shunt current from the power supply when the terminal voltage detection circuit detects that the terminal voltage exceeds a predetermined threshold, for example due to stored voltage in case the load is a battery, secondary cell, or capacitor, or due to counter EMF generated by the load in case the load is a DC motor, thereby reducing the power supply output voltage to compensate for the detected increase in terminal voltage.
