Technical details and manufacturing context for Stator/Sensor Head

Definition
The stator/sensor head is the fixed part of a position encoder or resolver system that contains the sensing elements (such as coils, Hall effect sensors, or optical detectors) which detect the position of the rotating rotor. It serves as the reference point for measuring angular displacement, speed, or direction in electromechanical systems.
Working Principle
The stator/sensor head generates or receives electromagnetic, optical, or magnetic signals that interact with the rotating rotor. As the rotor moves, it modulates these signals (through changing magnetic fields, light patterns, or inductive coupling), which the sensor head detects and converts into electrical signals representing position data.
Common Materials
Ferrite core, Copper winding, Epoxy resin, Aluminum housing
Technical Parameters
  • Outer diameter of the stator assembly (mm) Per Request
Components / BOM
  • Sensor Coil
    Generates or receives electromagnetic signals for position detection
    Material: Copper wire with enamel insulation
  • Core Lamination
    Provides magnetic path and reduces eddy current losses
    Material: Silicon steel
  • Housing
    Protects internal components and provides mounting interface
    Material: Aluminum alloy
  • Connector
    Electrical interface for signal and power connections
    Material: Plastic with brass contacts
Engineering Reasoning
0-150°C ambient temperature, 0-100% relative humidity non-condensing, 0-10g vibration (5-2000Hz), 0-500mT magnetic field interference
Hall-effect sensor saturation at 750mT magnetic flux density, insulation breakdown at 1500V RMS, thermal degradation of epoxy encapsulation at 180°C
Design Rationale: Hall-effect sensor output nonlinearity due to magnetic saturation beyond 750mT, dielectric breakdown of polyimide insulation at 30kV/mm electric field strength, glass transition temperature of epoxy encapsulation at 180°C causing mechanical stress
Risk Mitigation (FMEA)
Trigger Electrostatic discharge exceeding 15kV contact discharge per IEC 61000-4-2
Mode: Gate oxide breakdown in CMOS sensing ICs causing permanent signal loss
Strategy: Integrated TVS diodes with 5pF capacitance and 1.5kV clamping voltage at each signal pin
Trigger Mechanical misalignment exceeding 0.5mm radial or 1° angular offset from rotor
Mode: Signal amplitude reduction below 100mVpp causing position detection failure
Strategy: Precision mounting flange with 0.1mm concentricity tolerance and laser-aligned installation fixtures
