Product Advantages
1.High return efficiency
No need to add gearboxes, gearboxes, pulleys, using direct-drive motors to replace the traditional drive system energy saving rate can reach 8% -50%, most of the system can recover the equipment investment in 2-3 years. Significantly reduce operating costs and maintenance costs.
2. High-performance materials
The use of high-performance rare earth permanent magnet materials as the magnetic field source can provide a long and stable magnetic field (more than 15 years).
3.Noise
Relatively low-speed permanent magnet synchronous motor through the optimization of the structure to achieve the removal of the reducer, mechanical deceleration device, but also correspondingly reduces the vibration due to the belt drive, so it also reduces the impact of noise to a certain extent.
4. Maintenance-free
Small size products all adopt maintenance-free bearings, daily use does not require maintenance, especially suitable for food and pharmaceutical industries; large size products bearing maintenance is simple, high energy saving rate of the motor, especially suitable for mining, new energy and other energy-consuming industries; NdFeB magnets are temperature resistant to 120~180 ℃, suitable for conventional industrial occasions; SmCo magnets are temperature resistant to 350~550 ℃, suitable for special high-temperature occasions; the life span of the bearings can reach more than 100000h. The bearing life can reach more than 100000h.
5. Safe and reliable
Adopting finite element analysis software for heat dissipation optimization design, each type of motor has reliable heat dissipation capability with case temperature below 80℃ to ensure safety; the temperature of wire package does not exceed the insulation level, so the insulation of the motor is safe and reliable; reasonable runner design, ultimate heat dissipation capability.
