Explore our leading selection of industrial three-phase AC induction motors, high-voltage explosion-proof machinery, and custom drive systems engineered for horizontal mounting.
Within the spectrum of heavy industrial drivetrains, the horizontal foot-mounted configuration (standardized under IEC as IM B3 or NEMA as F1/F2) remains the foundation of robust machinery installations. Horizontal motors offer a low center of gravity, distributing dynamic structural loads evenly across base plates, which dramatically curtails vibration metrics (measured as velocity rms under ISO 10816 limits). By establishing a balanced structural stance, B3 horizontal mounting minimizes radial and axial misalignment stress on couplings, shafts, and adjacent bearings, thereby elevating operational longevity.
Shaanxi Nanfang Motor Technology Co., Ltd. serves as the premier authorized distribution partner for Wolong, connecting global heavy-industrial buyers with class-leading drive designs. Through Wolong's comprehensive ecosystem, we deliver optimized horizontal designs configured for harsh conditions, high torque, high/low voltage systems, and hazardous atmospheres.

Targeted horizontal motor solutions engineered to withstand extreme temperatures, corrosive atmospheres, and high mechanical stress.
We supply horizontal explosion-proof motors (Ex d, Ex e, Ex p, and dust-tight configurations) certified by European, North American, and Eurasian certification bodies. Perfect for refining, petrochemical, and chemical gas zones.
Offering options up to IE4 and super premium IE5/IE6 parameters, along with permanent magnet synchronous motors (PMSM). These solutions significantly lower operational energy consumption and carbon footprints.
We support a broad range of applications—from low-voltage small-frame systems to highly complex, customized, high-voltage positive pressure synchronous condensers.
Every element of our horizontal motors is engineered to withstand intense industrial use, incorporating structural redundancies and premium materials.
Our rotors feature robust squirrel-cage designs. Cast aluminum rotors are produced using centrifugal or high-pressure die-casting processes, integrating rotor bars and end rings into a solid, highly durable piece. For larger outputs, copper bar rotors are utilized, featuring secure mechanical bar locking and precise end-ring welding. High-speed units also feature custom protective rings to prevent centrifugal deformation.
Stator coils are wrapped with polyester film and glass-fiber reinforced tape, using high-mica-content tape. Following assembly, the entire stator core undergoes Vacuum Pressure Impregnation (VPI) with high-grade resins. This ensures an air-pocket-free insulation layer with excellent dielectric strength, high thermal conductivity (Class F or H), and outstanding moisture resistance.
Frames are designed using advanced multi-physics simulation platforms. Cast from high-strength grey iron or fabricated from structural steel, they provide excellent mechanical rigidity. The design isolates natural frequencies, dampens vibration transmission, withstands significant mechanical shocks, and features optimized cooling fins for efficient heat dissipation.
Comprising a balanced composite or aluminum fan, air guide cylinder, protective grid, and internal acoustic lining. The side-entry air intake design avoids obstructions, minimizes pressure drops, and reduces turbulence-induced noise. Rated at IP22 to IP55, it prevents debris entry while protecting personnel from moving parts.
Driving the future of horizontal motor platforms through digitalization, high-frequency VFD pairing, and IE5/IE6 efficiency benchmarks.
As power grid demands shift toward decentralized renewable energy sources and manufacturing systems move toward absolute automation, horizontal motors must transition from simple mechanical actuators into intelligent, ultra-efficient nodes. Wolong's R&D centers in Europe, China, and Japan are currently executing a comprehensive technological roadmap focusing on three core pillars:
By integrating wireless vibration sensors, high-precision thermal probes within stator slots, and flux leakage sensors, horizontal motors feed real-time telemetry into the Wolong i-Motor cloud platform. Machine-learning algorithms analyze key markers to predict winding insulation wear or bearing fatigue, preventing unexpected shutdowns.
Operating motors on variable frequency drives (VFD) often introduces harmonic currents and bearing-destroying shaft voltages. Our new designs integrate insulated bearings (typically silicon nitride ceramic balls) and shaft grounding rings to dissipate destructive currents safely, extending bearing life.
Utilizing Permanent Magnet Assisted Synchronous Reluctance (PMaSynRM) architectures, Wolong is bypassing standard induction limitations. By reducing rotor I²R copper losses, these motors achieve IE5 and upcoming IE6 efficiencies, maintaining peak performance even during partial load operation.
Operating from Wolong's advanced industrial bases, our production workflows leverage advanced automation, computerized quality gates, and digital testing bays. This vertically integrated manufacturing model ensures consistency across every frame and mounting size:
Our products carry comprehensive certifications to ensure seamless integration and regulatory compliance in any international market.
WOLONG has secured the majority of product certifications, enabling it to penetrate the international market, ensuring adherence to global mechanical and electrical performance standards.
Key considerations for engineering and procurement teams sourcing industrial horizontal motor platforms.
Purchasing heavy-duty industrial motors involves evaluation parameters that extend far beyond initial acquisition costs. Engineering teams and procurement managers must assess the Total Cost of Ownership (TCO), which includes energy efficiency, maintenance requirements, operational reliability, and parts availability.
Since energy consumption typically accounts for over 90% of a motor's lifecycle cost, upgrading from an IE3 to an IE4 or IE5 design can pay for itself within a few years of continuous operation, depending on local energy rates.
Ensure class ratings are matched to the operating environment. Standard IP55 protections are suitable for general outdoor dust and water exposure, while highly corrosive maritime environments require IP56 or IP66 designs with epoxy coatings and marine-grade hardware.
Evaluate shaft radial/axial load requirements to determine the optimal bearing type. For directly coupled horizontal motors, deep groove ball bearings are standard. However, belt-driven configurations often require heavy-duty roller bearings at the drive end to handle high radial loads.
