Compared to traditional motor, rare earth Permanent Magnetscoreless motor with a "big four" performance advantages: First, energy-efficient. Motor power factor is high, no iron loss, non-magnetic damping, efficiency is greatly improved. Demonstrate the practical application of the user, using the technology of 1.5 kW and 3 kW diesel power plant, compared with the traditional generator, saving rate of 40%.
Second, light and materials. Small size, weighs only a fraction of the traditional motor. Savings of 80% of the steel, silicon steel sheet of 100%, 50% copper. Third, speed is good. Motor speed and power to maintain constant frequency, frequency control system to simplify, speed range, high accuracy; easy to make a multi-polar, low-speed high-power motor, to cancel the gear box, pulley drive system, the direct drive. Fourth, and reliability. Motor temperature is low, the motor winding insulation using sophisticated packaging polymer materials, environmental adaptability, reliable operation.
Rare-earth Permanent Magnetscoreless motor compared with traditional motors, energy and materials, high performance; with the current advanced rare earth Permanent Magnetsmotor compared to the more efficient, lighter weight, better stability.
First reached the international advanced level in domestic
Asynchronous motor with the same general structure is easy to install, starting torque, strong overload capacity, high efficiency, high power factor, stable operation, low noise, easy maintenance and excellent performance. RWDQTNM motor uses class F insulation, protection class IP54, temperature of 150 ° can still work. RWDQTNM motor compared with other motor starting torque, and torque up to 3.8 times multiple. Reduce the starting current, small impact on the grid. RWDQTNM cast rotor processed using special materials for the solid core of high strength and rigidity, structure, mechanical structure is reasonable, never deformation, the phenomenon will not sweep bore; It is the core part of the magnetic circuit but also doubles as the winding, two were combined into one, efficient performance and stability. RWDQTNM rotor chamber full capacity, can be embedded in the magnetic energy sufficient to ensure that motor efficiency is much higher than other products. The magnetic field embedded in the rotor chamber, the replacement of magnetic field open cavity can be replaced, maintenance is very convenient. Across the magnetic field embedded in the material composition of the chamber with the outside world does not turn, no demagnetization phenomenon, which would ensure the long-term highly efficient and stable operation of the motor. RWDQTNM rare earth permanent magnet synchronous motor design of the rated power factor of about 0.98, higher than this value Shihai light load. After several years of application and field tests, saving effect is much higher than other motors, the average saving rate of the industrial applications of 8% or more, as the oil system for frequent oil changes in mechanical loading of special operating conditions, the average saving rate in the 18 % or more.
