摘要： Provided is a controlling device for a railway electric car, the controlling device being able to detect a slipping/sliding phenomenon during, in particular, high-speed travel and to exercise slipping/sliding control in an appropriate manner. A slip controlling unit 1 includes a first adhesion level index generating unit and a second adhesion level index generating unit. In a normal slipping state in which an acceleration changes instantaneously, torque control is exercised by using a first adhesion level index generated by the first adhesion level index generating unit based on an acceleration deviation and a speed deviation. In a slipping state during high-speed travel, because the acceleration deviation and the speed deviation are small, torque control is exercised by using a second adhesion level index generated by multiplying the first adhesion level index by a gain equal to or smaller than 1 generated by the second adhesion level index generating unit.

摘要： The invention relates to a method of controlling two or more commutator DC motors with permanent magnets in driving mechanisms for setting a position of furniture parts such as tables, beds, chairs etc., where particular driving mechanisms must maintain mutually defined speed independently on their different load. The invention consists in that during functioning of the motors is periodically disconnected power supply of the motors, while in the time of disconnecting the supply is detected the voltage of each motor, which is adjusted using calibration constant characteristic for each motor and the direction of rotation and according to the differences of such adjusted voltages of particular motors is adjusted the operating mode of each motor, by means of which is reached an effective regulation of particular motor run to mutually defined speed independently on their load. The invention also relates to a device for controlling two or more commutator DC motors with permanent magnets in driving mechanisms for setting a position of furniture parts such as tables, beds, chairs etc., where particular driving mechanisms must maintain mutually defined speed independently on their different load. The device consists of at least one power supply, with which are through power management blocks of particular motors coupled at least two motors, while with each motor is by its first input coupled a multiplier, where with its second input is coupled a calibration constant block, while the outputs of the multipliers are connected to the inputs of the first comparison element, whose outputs are connected to the inputs of a regulator, whose outputs are connected to the inputs of the power management blocks of particular motors, while on the second input of the regulator is by its output connected a timer clock.

摘要： A control for DC motors, in particular actuators driven by a DC motor for adjustment of furniture, such as tables, beds, chairs, etc. includes a pseudomotor which is capable of supplying a voltage that corresponds to the motor speed on the basis of the current and voltage supplied to the motor. The voltage of the pseudomotor is supplied to an adjustable power supply, where it is compared with an internal reference voltage and adjusts the voltage difference down to the smallest possible difference between the voltage of the pseudomotor and the internal reference voltage. For greater accuracy, the control additionally includes a compensation circuit configured to evaluate a dominating frequency in the commutator noise. Thus, there is provided a simple and low cost control for parallel running of two or more actuators.

摘要： A drive control system for a binding line having first and second separate binding-line segments, includes a first motor for driving the first binding-line segment, a second motor independent of the first motor for driving the second binding-line segment, and a controller coupled to the first and second motors. The controller is operable in an independent or asynchronous mode for controlling the first and second motors so that the first and second binding-line segments operate independently, and is also operable in a synchronous mode for controlling the first and second motors so that the first and second binding-line segments operate in synchronism with one another.

摘要： Functional element units are fixedly mounted on a circuit board, and unit-side connectors are electrically wired to base-board-side connectors. A predetermined wiring circuit has been formed on the circuit board, with the result that the wiring work is simplified as much, and the disused connectors can be disposed of, so that the number of connectors is reduced. In addition, the electrical connection of the functional element units through those connectors, provides the following effects: the wiring is orderly and reasonable, the number of wires is small, the occurrence of wiring errors is prevented, and in addition the application of external noises to the wires is prevented. That is, the operation of the motor control system high in reliability.

摘要： A digital proportional-integral controller for controlling the speed of a d.c. electric motor in a copying machine and synchronizing it with the speed of another motor in the copying machine. The proportional stage and the integral stage of the controller are each formed by an up/down counter which counts up or down depending upon the pulses of the actual speed signal and the reference signal. Logic circuits are provided for processing the speed signal pulses and the reference signal pulses before they are fed to the up/down counters. The controller also has an interface for a two-wire bus system over which data and commands for adjusting and varying the control parameters can be input.

摘要： A method for regulating the supply of weft thread on weaving machines includes the steps of winding the weft thread from a thread supply by means of a draw-off roller driven by a motor, supplying the thread to an accumulator, and controlling the draw-off roller motor by a pulse train generated on the basis of a set value and a second pulse train whose frequency is proportional to the main shaft of the weaving machine. By adjusting the set value, the speed of the draw-off roller can be adjusted to account for such factors as thread type, thickness extensibility and diameter, and also thread supply package diameter and variations in thread draw-off speed. A device for implementing the method of the invention includes, in a preferred embodiment, a cam, a set value setting unit, a shaft pulse generator for generating the second pulse train, a buffer, and a counter which adds the set value and the second pulse train to generate the first pulse train.
