Frequently Asked Questions (FAQ)

When investing in heavy-duty industrial machinery, engineering and procurement teams naturally require comprehensive technical details to ensure absolute confidence in their selection. To assist in your evaluation process, we have compiled the most frequently asked questions regarding the operational capabilities, structural design, and thermal management of our high-voltage AC motors.

Q1: What makes the box-type steel construction superior for heavy pump applications?

The welded steel plate box-type construction provides exceptional structural rigidity compared to standard cast iron frames. This advanced design minimizes chassis flex and actively dampens harmonic vibrations generated by massive industrial pumps, significantly extending the lifespan of internal components and ensuring quieter operation.

Q2: How does the PT100 thermal protection system function during continuous S1 duty?

The PT100 sensors are precision thermal resistors embedded directly into the motor windings and bearings. During continuous 24/7 (S1) operation, they provide real-time, highly accurate temperature readings to your facility's control systems, allowing for automatic load adjustments or safe shutdowns long before irreversible thermal damage occurs.

Q3: Can the cooling method be adapted if our facility lacks a dedicated industrial water supply?

Absolutely. While the IC81W (top-mounted air-to-water cooler) is highly efficient for facilities with plumbing infrastructure, sites without water access can easily opt for the IC611 (top-mounted air-to-air cooler) or IC01 (natural ventilation). This ensures optimal thermal management regardless of your specific site resources.

Q4: What is the specific mechanical benefit of the oversized roller bearings?

Industrial pumps and centrifugal machines exert tremendous radial and axial forces during operation. The oversized roller bearings in our motors are specifically engineered to absorb these extreme, continuous loads. This prevents shaft deflection, maintains perfect rotor alignment, and drastically reduces the frequency of bearing replacements.

Q5: Is it possible to customize the voltage for a specialized international facility?

Yes. As a direct manufacturer, we offer extensive electrical customization. While our standard options range from 380 V to 11000 V (including 3kv, 3.3kv, 6kv, 10kv, 11kv), our engineering team can custom-wind the stator to match the exact voltage and frequency requirements of your specific international power grid, ensuring plug-and-play compatibility.
