CNC machining of 42CrMo4, 40Cr, and 304/316L stainless steel shafts (splined, tapered, hollow, dual-extension) alongside custom IEC B5/B14, NEMA C-Face, and bespoke OEM mounting brackets with runout tolerances within ≤ 0.012 mm.
03 // ROTOR PRECISION
ISO 1940 G1.0 Dynamic Balancing
Every rotor assembly undergoes automated two-plane dynamic balancing to ISO 1940 Grade G2.5 or precision Grade G1.0, paired with genuine SKF, NSK, or FAG bearings for low acoustic noise (≤ 58–72 dB(A)) and L10 life exceeding 40,000 hours.
04 // INTEGRATED FEEDBACK & SAFETY
Brakes, Encoders & Thermal Sensors
Factory integration of spring-applied electromagnetic holding brakes (24V DC / 220V AC), optical/magnetic incremental and multi-turn absolute encoders, forced ventilation blowers (IC416), and embedded PTC thermistors or PT100 RTDs.
05 // ENVIRONMENTAL SEALING
IP55 / IP65 / IP66 / IP67 Protection
Viton® double-lip shaft seals, epoxy resin potted stator windings, anti-condensation space heaters, and C4/C5-M marine-grade polyurethane coatings for washdown food processing, chemical plants, and offshore equipment.
06 // METROLOGY & QUALITY CONTROL
100% Automated End-of-Line Testing
100% of motors undergo automated stator impulse surge testing, 1,800V–2,500V AC Hi-Pot dielectric testing, insulation resistance verification, and computerized dynamometer load testing with serialized inspection certificates.
