The permanent magnet variable frequency speed control integrated motor is an integrated industrial device that combines a permanent magnet direct drive motor and a frequency converter. It features high-speed operation and is specifically designed for equipment such as belt conveyors, hoists, and winches in the coal mining industry.
This motor adopts an integrated design, achieving a highly compact structure. This not only simplifies the installation process but also significantly reduces the equipment's footprint. In terms of electrical configuration, only a single main cable is needed to reach the main unit, simplifying wiring and overcoming power supply distance limitations, completely eliminating electromagnetic interference and ensuring system stability. Furthermore, in practical applications, this equipment effectively improves production efficiency, reduces maintenance costs, and shortens maintenance time, making it a highly efficient and reliable power solution for coal mining production scenarios.
Our company's permanent magnet variable frequency speed control integrated motor is a core power device specifically designed for belt conveyors, hoists, winches, and other equipment in the coal mining industry. Its technical parameters and performance design are tailored to the stringent requirements of industrial operations.
This motor has a rated voltage of 1140V, a power range of 160kW~500kW, and a speed that can be flexibly adjusted from 0 to 1500r/min, adapting to the power output requirements of different working conditions. It boasts an insulation class of H and an IP55 protection rating, effectively resisting interference from dust, moisture, and other factors in complex industrial environments, ensuring stable equipment operation. The water-cooled design provides excellent heat dissipation efficiency, and the 355 frame size further enhances the equipment's adaptability and durability.

Intelligent, efficient, green, and energy-saving, with high starting torque and strong overload capacity;
Innovatively integrating a permanent magnet motor and frequency converter into one unit simplifies drive configuration design and allows for more flexible drive layout; adopts advanced circuit topology design for higher power density;
"Zero" frequency conversion output distance: The system integration is unaffected by the frequency converter's output distance, completely eliminating the impact of long-distance power supply voltage spikes on motor insulation life;
Low cable requirements and less line interference; the integrated power supply eliminates the need for shielded cables and the need to consider radiation interference along the cable path, resulting in lower cable and installation costs.
