  • Rotary encoders for motors
    Constant-speed ac-induction motors don't really hold a constant speed. In an optical encoder, an LED typically shines light through a code disk and mask to illuminate a photodetector assembly. The slots in the disk and mask form a shutter that passes or blocks the light beam as the code disk
  • Integrated Drive Electronics for Brushless DC Motors
    for an angular position sensing system can include electro-optical switches (optical. encoders), most commonly a combination of light emitting diode (LED) and a phototransistor. A shutter. mechanism controls light transmission between the transistor and the sensor. The sensor voltages can. be processed
