This series of motors can be used to drive various general-purpose machinery, such as compressors, fans, water pumps, crushers, machine tools, coal mills, and transport machinery. They can also serve as prime movers in mines, the machinery industry, the petrochemical industry, and other industrial and mining enterprises.
Main features:
1. Compact structure, small size, and light weight.
2. Can replace traditional closed-cooling motors, offering high operating efficiency.
3. The overall structure (frame, end shields, etc.) adopts cast iron construction, with externally orthogonally distributed cooling fins on the frame. This structure provides good heat dissipation, high overall rigidity, and is robust and durable.
4. The frame and end shields are cast from high-grade cast iron, and the frame and feet can be cast integrally or separately. Good design ensures high strength and rigidity of the frame and end shields.
5. The coil core adopts an external pressing assembly method, offering good manufacturability and easy maintenance.
6. The windings adopt VPI (Vacuum Pressure Impregnation) technology, enhancing the reliability of the windings.
7. The coil core features special anti-corona treatment, enabling the motor to operate safely at high altitudes. The stator winding ends are securely fixed and neatly arranged.
8. The squirrel-cage rotor of the motor is typically designed with a die-cast aluminum structure. The rotor bars, end rings, and fans are formed in one piece, improving reliability and increasing the permissible load inertia. In summary, this squirrel-cage rotor can operate under harsh conditions and offers good electrical performance.
9. The die-cast aluminum rotor is manufactured using special processes.
10. The standard number of starts is 5,000 times per year.
11. It features high locked-rotor torque and allows a longer locked-rotor time.
12. All motor components are treated with special anti-corrosion processes, meeting the requirements for "three protections" (moisture-proof, mold-proof, and salt-spray-proof).
13. A special cooling structure is adopted, providing ideal cooling effects and low noise.
14. The terminal box features a compact structure, high protection rating, and reliable connection terminals. The cable entry is flexible, meeting multi-directional wiring requirements.
