FAQ

Q: What encoder resolution should I choose for high precision applications?

A: 17-bit encoders suit standard industrial automation and robotics, while 23-bit encoders are recommended for ultra-high-precision optical metrology and semiconductor wafer handling. Selection depends on controller compatibility and mechanical transmission accuracy.

Q: Does higher encoder resolution guarantee higher machine accuracy?

A: No. Encoder resolution is only one factor. Mechanical backlash, shaft runout, frame rigidity, and servo tuning heavily influence final positioning performance.

Q: Can Auric customize servo motors for non-standard space or electrical requirements?

A: Yes. We specialize in OEM customization, offering tailored winding voltages, custom stack lengths, modified flanges, special shafts, integrated planetary/harmonic gearboxes, and custom cable connectors.

Q: What information is required to get an accurate motor and drive quotation?

A: Please provide your required continuous/peak torque, rated/maximum speed, operating voltage, encoder preference, load inertia ratio, target positioning accuracy, and estimated annual quantity. Attaching mechanical drawings or load calculations helps expedite the review.

Q: Do your servo motors come with holding brakes?

A: Yes, electromagnetic holding brakes are available as an optional configuration across applicable motor series. Please specify brake requirements during your inquiry.
