Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical operating voltage range for this motor core? **A**: The directory lists a nominal voltage range of 3–12 VDC. However, the exact operating voltage for a specific model must be confirmed with the legal manufacturer or supplier, as it may vary based on the intended application and control circuitry. ### Q: How is the vibration amplitude measured and what does it indicate? **A**: Vibration amplitude is measured in grams (g) and is specified as 0.5–1.5 g at rated voltage. It indicates the strength of the haptic feedback. Higher amplitude generally provides stronger vibration, but the actual value depends on the load and mounting conditions. Always verify the amplitude for the specific model. ### Q: What standards are referenced for electrical safety and noise? **A**: The listed insulation resistance is a directory reference of ≥100 MΩ at 500 V DC and requires model-specific confirmation. IEC 60243-1 applies only to the listed dielectric strength test of ≥500 V AC. Noise level is referenced to ISO 3744, with a maximum of 40 dB(A) measured at 10 cm. These standards are for verification purposes; they do not imply certification of any specific product. ### Q: What are common signs that the motor core needs maintenance or replacement? **A**: Common signs include increased noise, reduced vibration amplitude, or erratic operation. These may indicate bearing wear, brush degradation, or magnet demagnetization. If the motor operates outside its temperature range (-20 to +70 °C) or voltage limits, it may fail prematurely. Regular inspection and verification against manufacturer specifications are recommended. ## 6.
