Ouli-Wolong MVE-M Single-Phase Vibrating Motor

Manufacturer: Shaoxing OLI-Wolong Vibration Machinery Co., Ltd. (OLI-WOLONG), a Sino-foreign joint venture established by Wolong Electric Group (Stock Code: 600580) and Italy's WAM Group OLI. Fully adopting Italian technology and processes, the company specializes in level sensors, vibration motors, and vibration rods. With 19 sales subsidiaries, 36 warehouses, and 7 manufacturing plants worldwide, OLI exports approximately 50% of its products to Europe, the US, and other regions, establishing itself as one of the world's leading manufacturers of vibration motors and pneumatic vibrators. Its three core product lines are industrial vibrators, flow aids, and concrete consolidation units. Product Series: The MVE-M single-phase series is designed for applications with single-phase power only. It offers two speed options: 2-pole (3000rpm) and 4-pole (1500rpm), with an excitation force range of 0.7~4kN and power output from 0.08 to 0.3kW. Available frame sizes are 10A0, 20A0, and 30A0. Powered by single-phase 115V 60Hz or 220V 50Hz, these motors include a running capacitor (4~12μF) and can be directly connected to residential or small workshop grids without requiring three-phase power. Construction & Technology: Features a robust housing designed via FEM finite element analysis, vacuum impregnation, FMEA analysis, and 3D quality inspection. Rated insulation class F, protection rating IP66, and continuous duty cycle S1. Equipped with a built-in PTC thermistor (130°C), special grease retention devices, and heat-resistant (tropicalized) treatment, ensuring an excellent power-to-weight ratio and optimized electrical design. Bearings & Lubrication: Low-power models use dedicated ball bearings pre-lubricated at the factory and require no maintenance. High-power models feature specialized cylindrical roller bearings with sufficient grease applied prior to shipment; do not add grease before installation. Excitation Force Adjustment: Eccentric weights are easy to adjust, available in Type A, Type B, and Type C. Type C utilizes sheet-type eccentric blocks with combinations of 5+5, 8+8, 9+9, and 12+12 sheets. Flipping up one sheet on each side reduces the 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 in the housing during bolt tightening, which could cause foot fractures. Use high-strength bolts of grade 8.8 or higher, grade 8 nuts, and flat washers matching the hole diameter. Tighten bolts to the specified torque. The mounting surface must be machined and must not be painted. Electrical Connection: Verify that voltage and frequency match the nameplate. Ensure power cables pass through cable glands and conductor cross-sections meet specifications. The yellow-green grounding wire must be reliably grounded. Before closing the terminal box cover, confirm that washers are correctly positioned to maintain the protection rating. Overload Protection: All vibration motors must be equipped with external overload protection devices. When operating two motors synchronously, each motor requires its own overload protection device, and the devices must be interlocked so that if one stops, the other immediately shuts down. Certifications: CCC and CE certified.
