Description

Measures the absolute angle of the flange, in radians, without loading it. Use it for position feedback in a servo loop.

Example

Resolver and Hall sensor A shaft turning at 10 rad/s read by a resolver, a Hall sensor, and an angle sensor.

Ports

Outputs 1

  • ysignal · rad

    Absolute angle, in radians. It is not wrapped to one revolution.

Conserving terminals 1

  • shaftflangerotational

    Measured flange. No torque is exchanged.

Equations

Modelica
y = flange.phi
flange.tau = 0

Assumptions and limitations

  • Ideal: no quantization, noise, or delay, unlike a real encoder.

Used in

These larger examples use it too. Open them from Examples in the app.
