摘要： The present invention is a method and apparatus that allows the torque of an electric motor to be increased allowing the motor to be operated at higher speeds and at higher torque without raising the supply voltage, thus allowing for a wider dynamic range of speed and torque to be realized. This is accomplished by connecting one or more capacitors in series with each motor winding, and selectively activating the capacitors at higher speeds where the frequency of the motor resonates with that of the capacitor(s). Switching a capacitor into the circuit with the motor in a particular frequency range allows higher currents to flow through the motor windings resulting in higher torque.

摘要： An image detecting apparatus comprises a rotating disk having pinholes that allow light to pass through, a photosensor for detecting the rotation of the disk, a CCD camera for capturing a confocal image of a specimen passed through the pinholes of the disk, a brushless DC motor for rotating the disk at a given speed, and an FPGA which produces a pulse-like brake signal having two levels for accelerating and decelerating the disk and its pulse width set variable and outputs it to the DC motor, thereby allowing the synchronization of the rotation of the disk with the image capture timing of the CCD camera.

摘要： The present invention overcomes the disadvantages of previously known motor controllers for centrifuge machines wherein a motor controller is provided for a centrifuge machine including a logic control module, one or more power cells, and one or more contactors. The logic control module is capable of interfacing with the main centrifuge controller and provides control over the power cells and contactors to provide a voltage ramp-up to accelerate the centrifuge basket. As such, the logic control module avoids the current draining problems associated with across the line starting of the centrifuge motor. The power cells receive a voltage from the main power supply, and output to the contactors variable power to control centrifuge motor speed. Further, the configuration of multiple contactors to reverse the power supplied to the centrifuge motor windings may eliminate the need for a second, reverse direction motor.

摘要： A device and control method to produce braking torque counter to motor rotation. A converter supplies multiple frequency AC power to the motor. A first frequency is supplied at the normal operating frequency/speed. A second frequency, different from the normal operating frequency, is supplied to produce braking torque. The level of braking can be controlled to generally consume some or all of the braking in the device or motor. More than one braking frequency may be utilized. In addition, the relationship between the normal and braking frequency(s) can be maintained to limit motor pulsation.

摘要： Electric motors, in particular geared motors, are often equipped with electromagnetically actuated mechanical brakes. In order to ensure that an excitation coil (3) can be operated with alternating-current mains supplies of various voltages, it is proposed to generate a unipolar voltage that varies over time with a certain period by means of a voltage source (2), the output voltage of which is positive and different from zero in a first time segment of this voltage period and in this first time segment has a maximal value, and in a second segment of the voltage period is zero or approaches zero. To pass an excitation current from the voltage source (2) to the excitation coil (3), a current path (15) is provided that is opened substantially at the beginning of the first time segment. The current path (15) is blocked again at a certain point within the first time segment, this point being selected such that the excitation current does not exceed a predetermined maximal value. During a time span in which the excitation coil (3) is or should be permanently excited, the opening and blocking of the current path are repeated in each voltage period.
