China Best Sales 22-45kw Mine Flameproof Permanent Magnet Synchronous Frequency Conversion Motor with Tbvf Series Simple Structure Small Size High Efficiency High Power Factor vacuum pump

Product Description



The mine flameproof permanent magnet synchronous frequency conversion motor is developed  and produced by Xihu (West Lake) Dis.n Electric Co., Ltd. It is a new type of mine cableway with permanent magnet frequency conversion technology as its core. Compared with traditional transmission drive system, the permanent magnet direct drive system has many advantages such as low speed,  energy saving, low noise, high torque, high transmission efficiency, stable operation, compact structure and small space. And it is suitable for all bad working conditions.



1. Improve transmission efficiency and reduce power waste

The transmission efficiency of the traditional drive system is less than 70%, and the energy consumption of its Y series asynchronous motor is only international IE1 level (equivalent to the national third level energy consumption standard). But the transmission efficiency of this system  is about 93%, and the energy consumption of its permanent magnet synchronous motor can reach the international IE4 level (higher than the national energy consumption standard), so that  the comprehensive energy-saving rate is more than 20% higher than that of the traditional drive system.

2. The system realizes soft start and maintenance-free.
The system uses the frequency converter to control the start, which can realize the slow uniform  speed start for the transmission, avoiding the shock of the instantaneous high current of the motor starting to power grid, and the mechanical shock of the instantaneous sharp increase of torque to the transmission system, thus reducing the power grid fault and mechanical fault of the system. Compared with the traditional driving mode, its dynamic safety factor is higher in the same conditions, which can effectively improve the safety of the whole machine of coal mine cableway device.

Maintenance-free, the permanent magnet synchronous motor (PMSM) adopts the way of connecting the driving wheel directly, removing the mechanical driving equipment in the middle, greatly reducing the probability of failure, thus greatly reducing the cost of maintenance and basically achieving maintenance-free.

3. Large starting torque

The permanent magnet synchronous motor of the system can output constantly the starting torque 2.8 times of the rated load, but the starting torque of asynchronous motor used in the traditional drive system under the same power conditions is 55% of the rated load, which cannot meet the system normal starting, for which it needs to increase the motor capacity to meet the starting torque, but the normal running of its system can waste resources.

4. Low noise and high power density.






TBVF-22/66 YC (660/1140), TBVF-30/66 YC (660/1140), TBVF-37/66 YC (660/1140), TBVF-45/66 YC (660/1140) series permanent magnet synchronous motor (PMSM) are mainly used in overhead equipment of coal mines and can be used in explosion-proof places or ground non-explosion-proof places. The series permanent magnet synchronous motor has the advantages of simple structure, small size, high efficiency and high power factor.
