Explore our leading range of high-performance electric drives engineered to meet international safety and energy standards.
Over the past three decades, China has evolved from a local manufacturing base into the global epicenter for industrial vibration motor engineering. Today, Chinese industrial vibration motor factories combine vast raw material supply chains (such as ultra-grade silicon electrical steel and premium insulated copper coils) with state-of-the-art automation systems. This integration enables the production of vibration motors and heavy-duty exciters that achieve parity with European and American engineering standards, while offering unparalleled cost-to-performance advantages.
By leveraging advanced material science and digital structural testing, manufacturers in China are no longer merely assembling components; they are designing integrated solutions for complex industries. Shaanxi Nanfang Motor Technology Co., Ltd, as the authorized distributor of the globally renowned Wolong Group, stands at the frontier of this manufacturing shift. We provide industries worldwide with specialized vibration systems that drive productivity across screening, feeding, conveying, and compaction processes in high-risk, heavy-duty environments.

Wolong acquired a 97.94% stake in the Austrian ATB Group, integrating centuries-old brands like Morley (underground coal mining) and Laurence Scott (nuclear and marine generators). Combined with CNE (China's leading explosion-proof base), we deliver unparalleled Ex-d and Ex-e safety ratings.
Brook Crompton brings over 100 years of low and medium voltage motor heritage. Together with Schorch (Germany, est. 1882), which excels in high-power driving systems for petrochemical platforms, maritime networks, and oil exploration fields, we ensure extreme reliability.
Our long-term collaboration with OLI (world leader in MVE vibration motors) gives us access to top-tier rotary and linear vibratory designs. In 2018, General Electric's industrial motor business joined Wolong, reinforcing our capacity to design robust heavy-duty motors.
A detailed breakdown of our robust motor design, built to withstand continuous vibration loads.
Our rotors feature an advanced squirrel cage design, engineered for high start-up torque and fatigue resistance under cyclic vibration. For low-voltage standard drives, we employ centrifugal or high-pressure die-cast pure aluminum rotors to ensure structural integrity and reduce thermal expansion stresses. For larger capacity systems, we use heavy-duty copper bar rotors welded to the end rings using advanced induction welding technology. This guarantees electrical performance and mechanical strength during rapid acceleration.
The stator coil is wrapped with high-quality polyester film and reinforced glass cloth mica tape to resist electrical breakdown and mechanical shock. The entire core undergoes our digital Vacuum Pressure Impregnation (VPI) cycle, which fills any microscopic voids with high-grade, moisture-resistant epoxy resin. This process creates a solid, heat-dissipating structure that is highly resistant to chemical attack, damp environments, and severe mechanical forces.
Using structural and fluid multi-physics simulations on our proprietary digital platforms, our motor frames are designed with ample structural margins. Cast from high-strength gray cast iron (or fabricated steel for customized orders), these frames isolate internal resonant frequencies from external vibratory stresses. This reduces bearing wear, maintains low noise levels, and optimizes heat dissipation under continuous (S1) running conditions.
Our cooling system features a light, vibration-resistant fan cover body, an air guide cylinder, and integrated sound-absorbing panels. The air intake is positioned laterally to prevent blockages from surrounding debris and structures. Rating IP22 or above, the system prevents contact with rotating blades while maintaining optimal airflow to control temperature rise.

How our heavy-duty vibration and explosion-proof motors serve critical sectors around the globe.
For mining screen decks, feeders, and separation plants. Operating in harsh environments, our mining motors, reinforced with Morley and TestSafe certifications, deliver consistent exciter output without thermal overload, managing material flows of over 1000 tons per hour.
We supply explosion-proof motors for high-pressure fluid transfer, gas compression, and refinery ventilation systems. Features like flameproof enclosures (Ex d / Zone 1 & 2) prevent internal electrical faults from escaping into volatile outside environments.
Used to drive vibrating tables, bin activators, and industrial hoppers in steelworks and concrete production. Designed to handle high inertia starts and load changes, these motors prevent line blockages and support automated factory logistics.
For international buyers and procurement engineers, sourcing vibration motors from China requires verifying key performance and safety criteria. To ensure long-term reliability, check the following variables during vendor audits:
Ensure the manufacturer can calculate and match the out-of-balance eccentric weights to your equipment design and vibration patterns.
Verify that the factory utilizes complete vacuum-pressure impregnation (VPI) rather than simple dip-varnishing. VPI prevents air voids, protecting the motor against moisture and premature failure.
Heavy duty vibration motors require reinforced roller bearings (e.g., FAG or SKF spherical roller bearings) to manage high radial loads and centripetal forces.
Expert engineering answers to common technical queries about industrial vibration and explosion-proof motors.
Selecting a motor requires calculating the required centrifugal force (measured in kg or kN), working frequency (RPM corresponding to 2, 4, 6, or 8 poles), mechanical amplitude, and total vibrating weight (including the product charge). For high-moisture or volatile material, you must also specify the correct IP rating and explosion-proof class (such as ATEX Ex d or Class I Div 1).
Traditional varnish dipping leaves micro-air pockets within the stator windings, which can trap moisture and heat, leading to premature insulation failure under continuous vibration. Our VPI process extracts air under vacuum before injecting specialized resin under high pressure. This results in a solid, void-free winding assembly that improves thermal conductivity, moisture exclusion, and overall mechanical strength.
Australia maintains strict safety guidelines for coal mining operations (underground and open-cast). TestSafe acts as a key regulatory gateway. Possessing TestSafe-certified motors ensures compliance with local Australian safety rules, proving that the drive units can operate reliably near volatile coal dust and methane pockets.
Yes. By coupling explosion-proof or standard vibration motors with a high-performance Variable Frequency Drive (VFD), operators can adjust the frequency (speed) and control the vibratory force. This configuration allows for real-time adjustments to material feeding speeds and conveyor volumes while protecting the motor from starting-current spikes.
