Harmonic Drive servo component FHA-11C-30-E200-C

Abstract

The Harmonic Drive servo component FHA-11C-30-E200-C is a device used in servo systems to control the operation of mechanical components. It serves as an auxiliary motor with an indirect variable speed mechanism. Servo motors enable precise control over speed and positional accuracy, converting voltage signals into torque and rotational speed to drive controlled objects.

In typical control systems, the step response is a key indicator used to evaluate the speed and accuracy of the system's response. It includes several parameters:

- Overshoot : Measures the approximate standard of system stability.

- Rise Time : Time taken for the maximum overshoot to occur.

- Settling Time : Time required for the response to settle within a specified percentage (typically ±2% or ±5%) of the steady-state value.

- Half-peak Time : Time taken for the response to rise from 10% to 90% of the steady-state value.

- Steady-state Error : Error in the output response when it reaches a steady state.

Frequency response analysis evaluates how well the system tracks a sinusoidal input signal. Parameters include:

- Resonance Peak of Frequency Response : Maximum peak amplitude of the output response.

- Resonance Frequency : Frequency at which the resonance peak occurs.

- Bandwidth : Frequency at which the output frequency response decreases to half of its maximum value.

Pneumatic servo mechanisms, using compressed gases as working fluids, are suitable for high-power control systems. However, due to the compressibility of gases, they are not ideal for high-speed responses. Nevertheless, gas leaks are manageable, and the low cost of gas makes them widely used in general factory applications.

In summary, servo mechanisms are designed to track and control systems accurately. Performance evaluation considers both the system's ability to respond rapidly to changes in input (step response) and its ability to track sinusoidal input variations (frequency response).
