Ouli-Wolong MICRO Micro Vibration Motor

Manufacturer: Shaoxing OLI-Wolong Vibration Machinery Co., Ltd. (OLI-WOLONG), a joint venture between Wolong Electric Group Co., Ltd. (Stock Code 600580) and Italy's WAM Group OLI. Fully importing Italian technology and craftsmanship, we specialize in producing level sensors, vibration motors, and vibration bars. OLI operates 19 sales subsidiaries, 36 warehouses, and 7 manufacturing plants globally. Approximately 50% of our products are exported to Europe, the U.S., and other regions, making us one of the world's leading manufacturers of vibration motors and pneumatic vibrators. Our three core product lines are industrial vibrators, flow aids, and concrete compactors. **Series Positioning:** The MICRO series features 2-pole models with low excitation force, delivering 0.2~0.4kN (22~40kg) excitation force, 30~70W output power, weighing only 1.8~2.2kg, and measuring 145~161mm in total length. Available in single-phase 220V (-M suffix) or three-phase 380V versions, each unit ships with a 1m cable (single-phase includes 1+1m). Ideal for small hoppers, precision feeders, and compact screening equipment with limited installation space. Catalog specifications indicate an excitation force range of 0.04~0.4kN, output power of 0.03~0.07kW, and voltage options of three-phase 220V~460V at 50Hz or 60Hz, and single-phase 115V at 60Hz or 220V at 50Hz. **Structure & Craftsmanship:** Robust base designed via FEM finite element analysis, vacuum impregnation process, FMEA analysis, and 3D quality inspection. Insulation class F, IP66 protection rating, S1 continuous duty cycle. Features built-in PTC thermistors (130°C), special grease retention system, and heat-resistant treatment for tropical conditions, offering superior power-to-weight ratio and optimized electrical design. **Bearings & Lubrication:** Low-power models use dedicated ball bearings pre-lubricated at factory—no maintenance required. High-power models employ specialized cylindrical roller bearings with sufficient factory-applied grease; do not add grease before installation. **Excitation Force Adjustment:** Eccentric weights are easily adjustable, categorized as Type A, B, and C. Type C uses plate-style eccentric weights with combinations of 5+5, 8+8, 9+9, and 12+12 plates. Flipping up one plate on each side reduces excitation force by approximately 40%, 25%, 22.2%, and 16.7% respectively. **Installation Requirements:** Mounting surfaces must be flat with flatness tolerance under 0.25mm to prevent shell stress fractures during bolt tightening. Use high-strength bolts rated 8.8 or higher, 8 grade nuts, and flat washers matched to hole diameter, tightened to specified torque values. Surfaces must be machined and cannot be painted. **Electrical Connections:** Verify voltage and frequency match nameplate ratings. Ensure power cables pass through cable glands with conductor cross-sections meeting requirements. Yellow-green grounding wires must be reliably grounded. Confirm washer placement is correct before closing the junction box cover to maintain protection rating. **Overload Protection:** All vibration motors require external overload protection devices. When using two motors synchronously, each must connect to its own overload protector with interlocking functionality; if one stops, the other immediately halts. **Certifications:** CCC and CE certified.
