Technical Advantages of medium voltage electric motors
Our products incorporate four critical innovations. The closed air-air cooling system maintains optimal temperature without external water dependencies. High-voltage anti-corona insulation withstands continuous operation at 10kV with less than 2% degradation over 20 years. Increased safety terminal boxes provide 40% greater creepage distances than standard designs. Special rotor-stator geometry eliminates hot spots during startup surges exceeding 600% rated current.
The IC611 cooling architecture circulates internal air through top-mounted heat exchangers. This reduces installation costs by 35% compared to water-cooled alternatives while preventing scaling and corrosion issues.
Production Process
Every motor undergoes seven quality checkpoints. Stator winding uses vacuum pressure impregnation at 0.08MPa for complete insulation penetration. Rotor balancing achieves G2.5 grade precision. Dynamic testing simulates 150% overload conditions for 30 minutes. High-voltage dielectric tests verify 2.5× rated voltage withstand capability. Final assembly occurs in Class 10,000 cleanrooms monitored by SAP management systems.
Industry Applications
Medium voltage electric motors power critical equipment across sectors:
· Oil & Gas: High-pressure compressors operating continuously for 8,760 hours annually
· Mining: Main shaft hoists handling 50-ton payloads with precise speed control
· Water Treatment: Circulation pumps delivering 5000m³/hour flow rates
· Steel Manufacturing: Rolling mill drives requiring 100,000 N·m torque output
· Chemical Processing: Explosion-proof ventilators in hazardous Zone 1 environments
Customization Capabilities
We adapt five key parameters to your specifications. Voltage configurations adjust between 3000V-11000V with ±5% tolerance bands. Shaft extensions modify from standard 200mm to custom 500mm lengths. Bearing systems upgrade to FAG or NSK based on load profiles. Terminal box orientations rotate to match site cable routing. Mounting arrangements convert between horizontal IM1001 and vertical IM9101 configurations within 15 days.
Special applications receive dedicated engineering support. Our team modifies cooling capacity for ambient temperatures ranging from -25°C to +55°C. Altitude compensation maintains rated power up to 2000 meters elevation.
Reliability Testing & Certifications
All units pass GB 10068 standard verification. Temperature rise tests confirm Class F insulation with Class B rise limits. Vibration levels measure below 2.8mm/s per ISO 10816-3. Ingress protection reaches IP54 as standard, upgradeable to IP55. Our quality management holds ISO9001:2000, CRCC railway certification, and CQC system approval. Motors carry CCC, CE, UL, and GOST marks for global deployment.
Insulation resistance exceeds 1000MΩ at 25°C after 48-hour high-pot testing. PT100 temperature sensors monitor bearing and winding hotspots with ±0.1°C accuracy.
