摘要： A method may include receiving, via one or more processors, back electromotive force (EMF) data associated with each motor electrically coupled to a printed circuit board and determining, via the processors, a corresponding motor controller associated with each motor based on the EMF data. The motor controllers may be electrically coupled to the printed circuit board. The method may also include automatically adjusting, via the processors, circuit connections associated with the printed circuit board to route wiring that controls each motor to the corresponding motor controller.

摘要： A windshield wiper control system has operations controlled by single touch actuators. A first such actuator provides for initiation of wiper operation in low speed with the first actuation and alternate high and low speed operation with additional actuations. A second such actuator stops wiper operation and, if actuated while the wiper is not running, initiates a single wipe of the wiper. A further actuator may be provided for initiation of either programmed or operator controlled wash operation, depending on the length of actuation. A final actuator may be provided for two touch intermittent wiper operation, in which the operator sets the delay time by two consecutive touches. Variations are described for either depressed park or non-depressed park systems.

摘要： A flip-flop is arranged to be set by a first comparator and reset by a second comparitor. A first capacitor and a first resistor are connected between the input terminals of the circuit with the first comparator connected across the first resistor and the second comparator connected across the second resistor. The flip-flop is set and reset with time delays determined by the charging times of their respective associated capacitors. No external bias supply is required.

摘要： Pressing a release turns on, or triggers, a bistable electronic switch, such as a multivibrator or a semiconductor tetrode, which in turn renders an amplifying transistor conductive through which an electromagnet is energized, closing a switch that operates the motor of the photographic apparatus. Re-pressing the release shuts off, or reverses the state, of the bistable switch, and thereby turns off the amplifying transistor. Another release is so connected that the bistable multivibrator is conductive, or triggered to the right state, as long as the release is depressed. The two releases can be combined into a single release by using a selector switch.

摘要： The present invention refers to a starting method with two-levels modified and discrete fixed-time or fixed-frequency hysteresis current controller, under high load conditions, of a BLDC motor (10) with trapezoidal-shaped induced voltages, wherein the BLDC motor (10) is driven by an inverter bridge (30) with only one current sensor (20) positioned in the busbar, controlled by means of a processing unit associated to an analog-digital converter, wherein the novelty basically comprises the fact that:
the intensity of the BLDC motor current (Im) is controlled by means of the two-levels and discrete fixed-time or fixed-frequency hysteresis current controller.-

摘要： A control system may include a processor that may receive a first dataset associated with power properties of a rotating load device coupled to a relay device. The processor may also determine frequency properties based on the power properties and determine a switching profile to control moving a first armature of three armatures in the relay device based on the frequency properties. The switching profile is configured to control movement of the first armature between a first position and a second position, and wherein the switching profile comprises a firing angle for moving the first armature with respect to an electrical waveform, a second armature, and a third armature. The processor may then control a current provided to a relay coil of the relay device based on the switching profile, such that the relay coil causes the first armature to move.

摘要： The objective is to provide a motor control apparatus that suppresses a steep rush current to a charging circuit and that can quickly start driving of a motor without depending on a current-limiting resistor. A motor control apparatus according to the present disclosure includes an inverter for driving a motor, a charging circuit for supplying electric power to the inverter, a relay circuit for connecting a charging circuit and a DC power source, a control unit for controlling the inverter and the relay circuit, and a pre-charging circuit that is provided in parallel with the relay circuit, that starts charging from the DC power source to the charging circuit after a power switch for connecting an external power source with the DC power source is turned on, and that completes charging of the charging circuit before the control unit starts operation thereof.

摘要： A point-on-wave relay device includes a first contact relay and a second contact relay in series with the first contact relay. A first state of the first contact relay in conjunction with a first state of the second contact relay causes a point-on-wave open operation and second state of the first contact relay in conjunction with a second state of the second contact relay causes a point-on-wave close operation.

摘要： The present invention relates to a DC motor for hoist machine that is essentially a design of applying DC brushless inverter motor in the hoist machine. The stator and rotor of the brushless motor are formed in such a manner that a plurality of magnets are placed with alternation in polarity into the inside of the rotor of motor to generate main magnetic field, and that a current is supplied to the windings inserted within the block made of silicon steel lamination to exert push force. The integration of the application of DC brushless inverter motor combined with the electric and electronic elements gradually brings about inverter-controlled technology with maturity, by which excellent energy-saving effect can be obtained in case of the application having variable load, due to the fact that the inverter control has better manipulation property and better features of motor-output, and possesses high torque-output and better manipulation property in low-speed of rotation running condition. Furthermore, a speed-regulation button is provided on the push button switch of the present invention, by which the rotation speed can be regulated directly so as to increase the entire performance in use.
