High Voltage Slip Ring

Brief Introduction

The high voltage slip ring motor, as a YRKS Water Cooled Slip Ring HV Motor, is welded with box-type steel plates, so it is very strong and will not be damaged after many years of use. It is lightweight and rigid, so follow-up maintenance costs are low. The product has a low temperature rise and comes with a fan, which can maintain a certain temperature. It consumes low energy, but high power, so it is a good energy-saving product. The product has little vibration during operation, which also prolongs its service life to a certain extent. It is mainly used in petroleum, chemical, coal, power station, metallurgy, textile, medicine and other industries. Most of them are machine functions such as rolling mills, winches, blowers, and grinders. The product has been widely praised by domestic and foreign customers and is a good product that has been tested by the market.

The high voltage slip ring motor employs a modular steel enclosure fabricated through robotic welding technology. This construction methodology delivers exceptional structural integrity, with finite element analysis confirming yield strength exceeding 355 MPa-ensuring decades of reliable operation in heavy-duty industrial environments. Its optimized mass-to-rigidity ratio (validated per ISO 12100:2010) minimizes foundation stress while substantially reducing lifecycle maintenance requirements.

Integrated dual-circuit thermal management combines forced-air ventilation with closed-loop water cooling, maintaining winding temperature rise below 55K (Class F insulation) even during sustained 110% overload conditions. Energy efficiency metrics surpass IEC 60034-30 IE4 requirements, achieving 97.2% nominal efficiency at 75% load with power factors above 0.92. Vibration characteristics meet ISO 10816-3 Grade A specifications, with velocity magnitudes below 1.8 mm/s across all operating speeds. This mechanical stability contributes to a certified 100,000-hour MTBF (Mean Time Between Failures) rating.
