Technical details and manufacturing context for Feedback device

Definition
A critical component within linear motors and servo motors that continuously monitors the motor's actual position, speed, or torque and transmits this data back to the control system. This feedback enables closed-loop control, allowing the controller to compare the actual performance with the commanded input and make precise adjustments to minimize error and ensure accurate motion.
Working Principle
The device detects physical parameters (e.g., position via optical or magnetic encoding, torque via strain gauges) and converts them into an electrical signal (analog or digital). This signal is transmitted to the motor drive/controller, which processes it to calculate any deviation from the target command and adjusts the power output to the motor accordingly.
Common Materials
Aluminum alloy, Stainless steel, PCB (Printed Circuit Board), Optical glass/encoders, Magnetic materials (for resolvers/encoders)
Technical Parameters
  • Resolution, defining the smallest detectable change in position. (bits or pulses/rev) Customizable
Components / BOM
  • Scale/Rotor Part
    Provides the physical reference pattern (optical marks, magnetic poles) that is read by the sensor head.
    Material: Glass, steel, or aluminum with coating
  • Sensor Head/Reader
    Detects the pattern on the scale/rotor and converts it into an electrical signal.
    Material: PCB with photodiodes (optical) or Hall-effect sensors (magnetic), housed in aluminum
  • Signal Conditioning Circuit
    Amplifies, filters, and digitizes the raw sensor signal for transmission to the controller.
    Material: PCB with integrated circuits
