• Souped-up servoamps
  direct control over drive currents at all speeds. In conventional drive methods, when the alignment deviates from 90°, a fraction of drive current is applied to correct the problem. This usually ends up generating more heat rather than torque. The greater the departure from 90°, the worse the torque...
• Power OP Amps
  ) separately to the same point. Improper grounding of test equipment also causes difficulties. A common recommendation is to eliminate any direct ground connection between the signal generator and oscilloscope timing input. Although a POP may be rated to dissipate 90 W continuously, it cannot do so unless...
• May the force loop be with you
  control with a force feedback signal eliminates hysteresis. The graph shows the measured output force of a high-thrust linear motor in combination with a simple amplifier and strain gage in a closed-loop configuration. Industrial applications such as welding, grinding, and material testing require...

  strength. If it s a wired connection, you will need to connect the amplifier directly to your phone through your phone s accessory port, while a wireless connection is more universal since it doesn t require a direct connection to your phone. Problem: I m interested in purchasing signal boosting...
• Servos adapt to their loads
  Nonlinear motor control is a novel way to handle production lines that demand quick changeovers An example of NCT-based servodrives is the XtraDrive line of servoamplifiers by YET Inc. in Manchester, N.H. YET servos include standard rotary, direct-drive, and linear versions. The XtraDrive...

  ," he explained. Fluoroscopy uses low-dose radiation to minimize exposure. Existing digital imaging technology provides poor image quality at the low X-ray levels. To improve on this, Karim and colleagues added a signal amplifier directly into the pixel readout circuit, creating the first "active...
• Good Vibrations
  the ink is removed, a conductor pattern remains. The polyester diaphragm is tensioned in a frame and terminations are added. When the conductors are in the presence of a magnetic field and current is supplied from an audio amplifier, the diaphragm will move with the audio signal. The disadvantages...
• Limited-Angle Torque Motors
  A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180 . But they are widely used to operate servovalves, direct laser mirrors, position missile-guidance radar antennas, open shutters...
• Correcting errors that never happen
  constants. This is primarily due to the relationship between low inertia and low impedance in today's linear and direct-drive rotary motors. OBSERVER-BASED MOTION CONTROL. Because standard servosystems are error driven and therefore reactive, they suffer lag between the commanded and actual positions...
• Sensor Sense: Piezoelectric Force Sensors
  to a charge amplifier or converted to a low-impedance signal within the sensor. The use of the direct sensor output demands that any connector, cable, and charge amplifier input must maintain a high insulation resistance on the order of >10≠″ Ω. Low-impedance quartz sensors have an internal MOSFET...
