Ouli-Wolong MVE Standard Series Vibrating Motor (4-pole, 1500rpm)

Manufacturer: Shaoxing OLI-Wolong Vibration Machinery Co., Ltd. (OLI-WOLONG), a Sino-foreign joint venture established by Wolong Electric Group Co., Ltd. (Stock Code 600580) and Italy's WAM Group OLI Company. The company fully imports Italian technology and craftsmanship to specialize in producing level indicators, vibration motors, and vibration rods. OLI operates 19 sales subsidiaries, 36 warehouses, and 7 manufacturing plants globally, with approximately 50% of its products exported to Europe, the US, and other regions. As one of the world's leading manufacturers of vibration motors and pneumatic vibrators, OLI's three core product lines are industrial vibrators, flow aids, and concrete compactors. Product Series: MVE Standard Series 4-pole models feature a synchronous speed of 1500rpm, the most widely used general speed grade in vibration equipment. Excitation force ranges from 0.3~14 kN, output power from 0.03~8.9 kW, and frame sizes from 10A0 to 100A0. Rated for three-phase power of 220V~690V at 50Hz or 60Hz; special voltage and frequency configurations are available upon request. Design & Engineering: Features a robust frame designed via FEM finite element analysis, vacuum impregnation, FMEA review, and 3D quality inspection. Insulation class F, protection rating IP66, continuous duty S1, and built-in PTC thermistors (130°C). Equipped with a special grease retention system and heat-resistant treatment for tropical environments, offering an optimized power-to-weight ratio and electrical design. Bearings & Lubrication: Low-power models use dedicated ball bearings pre-lubricated with specialized grease requiring no maintenance. High-power models use dedicated cylindrical roller bearings pre-filled with sufficient grease; do not add grease before installation. Excitation Force Adjustment: Eccentric weights are easy to adjust, categorized as Type A, Type B, and Type C. Type C uses sheet-type eccentric weights with combinations of 5+5, 8+8, 9+9, and 12+12. Flipping up one sheet on each side reduces excitation force by approximately 40%, 25%, 22.2%, and 16.7% respectively. Installation Requirements: The mounting surface must be flat with a flatness tolerance below 0.25mm to prevent internal stress on the housing during bolt tightening, which could cause foot fracture. Use high-strength bolts of grade 8.8 or higher, grade 8 nuts, and flat washers matching the hole diameter; tighten to specified torque values. Mounting surfaces must be machined and must not be painted. Electrical Connections: Verify that voltage and frequency match the nameplate. Power cables must pass through cable glands with conductor cross-sections meeting specifications. Green-yellow grounding wires must be reliably grounded. Before closing the terminal box cover, ensure gaskets are correctly positioned to maintain the protection rating. Overload Protection: All vibration motors require external overload protection devices. When two motors operate synchronously, each must have its own overload protection device linked together so that if one stops, the other immediately stops. Certifications: CCC and CE certified.
