摘要： In a method and device for controlling several stepping motor modules in printing or copying machines, sets of ramp data are centrally calculated in a computer in a calculation phase and are transmitted via a bus system to one logic unit each in a loading phase. The ramp data are stored in the stepping motor modules in non-volatile memories and are loaded to corresponding main memories depending on operating conditions. When a stepping motor module is operational, the current set of ramp data is transmitted by a control unit. A start signal transmitted by the control unit initiates the conversion of the set of ramp data selected in the corresponding logic unit into impulses of variable distance.

摘要： Two motor fans are driven by two 4-pole direct current motors, respectively. Rotational speed of the two motors is controlled in three stages, namely low speed, intermediate speed and high speed. Specifically, at the time of low speed operation the two motors are connected in series with four poles, at the time of intermediate speed operation the two motors are connected in parallel with three poles, and at the time of high speed operation the two motors are connected in parallel with four poles.

摘要： A plurality of motors for use in driving accessories on a vehicle, are each powered by three-phase current. A single controller controls the supply three-phase current to the plurality of motors. In another aspect of the invention, pseudothree-phase current is created from a direct current voltage source. A chopping circuit chops the voltage into a plurality of pulses, and a phase shift circuit then creates phase-shifted power signals from those pulses. The present invention thus enables the use of three-phase alternating current motors on a vehicle to drive accessories. This reduces the cost and size of the required motors.

摘要： An electric vehicle accessory motor drive power supply system (40) that utilizes a single power supply design to provide efficient variable speed motor control to both brushless and brush-type DC motors (42,44). The power supply system includes at least one of each type of motor along with a first DC-DC converter (46) that provides operating power to the brushless motor (42) and a second DC-DC converter (48) that provides operating power to the brush-type motor (44). Both converters (46,48) have a power input (52) connected to the electric vehicle's high voltage bus (50) and each includes a data input (54) for receiving a speed control signal (SC) indicative of desired motor speed, as well as an output (56) for providing a motor drive signal to its associated DC motor (42,44). Each of the converters (46,48) is operable in response to its received speed control signal to convert operating power from the high voltage bus (50) into a lower voltage variable motor drive signal that is provided to its associated motor (42,44) via its output (56). The variable drive signal can be either a variable DC voltage signal or a pulse-width modulated signal. With this arrangement, a single converter design, including a single speed control interface, can be utilized to operate both brush-type and brushless motors. Furthermore, the system permits more efficient operation of the brushless motors since it obviates the need for speed control electronics on the motor itself and therefore eliminates the relatively inefficient use of cascaded PWM stages.

摘要： A load in an electrical apparatus is driven by two motors M1, M2. Switching means (R1, R2) switches the motors M1, M2 between: a series configuration, in which the motors M1, M2 are connected in series across a power supply and driven with a dc supply; and a parallel configuration in which the motors M1, M2 are connected in parallel across the power supply and driven with an ac supply. In the series configuration, a bridge rectifier BR is switched across the ac supply to provide the dc supply for the motors M1, M2 and in the parallel configuration, the rectifier BR is removed from the circuit. The arrangement can be used to drive a drum of a washing machine or a load in some other kind of appliance.

摘要： The present invention provides a circuit for operating a plurality of bi-directional motors, each motor having a pair of terminals disposed across the motor. The circuit includes a common half bridge for providing one of power and ground to one of the pair of terminals across each motor. A plurality of particular or individual half bridges, one particular half bridge for each motor, provide the other of power and ground to the other of the pair of terminals across each motor. A controller selectively controls the common half bridge and the particular half bridges to supply power in either direction across the pair of terminals of one or more of the motors. In a preferred embodiment, the controller selectively controls the common half bridge and the particular half bridges to independently pulse width modulate power in either direction across the pair of terminals of one or more of the plurality of motors. To simultaneously operate two or more motors in the same direction or opposite directions, the controller selectively controls the common half bridge and the particular half bridges to energize the two or more motors in a sequential or random order.

摘要： An automotive steer-by-wire system is disclosed that includes a first network. The first network connects a first set of controllers for controlling a first set of motors. The steer-by-wire system further includes a second network that is independent of the first network and connects a second set of controllers for controlling a second set of motors. The steer-by-wire system includes a third network that connects the first set of controllers and the second set of controllers for controlling the first or second set of motors if the first or second network is inoperative, whereby information is transmitted via the third network independent of the first network and the second network.
