Product Description

660/1140V Explosion-proof Permanent Magnet Motor Used in the Mine

One,Product Introduction
"The TBVF series of the explosion-proof permanent magnet synchronous motor used in the mine" whose rated voltage is 660/1140V applies to the mine methane explosion environment. According to the application needs, it can drive the mine belt conveyor,scraper conveyor and other transport system directly. Compared with the traditional drive system, the permanent magnet direct-drive system gets rid of the reducer,hydraulic coupler,CST and other mechanical soft-start devices. Compared with the original system, it has the characteristics of high efficiency,energy saving,low noise,maintenance free,high starting torque,running smoothly and so on. Besides, the product is widely used in the ports,oil fields,mining machinery and other fields which has been unanimously praised by customers.

Two,Technical Features

1,The motor is high-efficiency and power-saving whose efficiency can achieve a primary energy consumption(IE4) standard.
2,The system adopts vector control technology, so the starting torque is higher, the dynamic response is faster and the overload ability is stronger.
3,In the case of the multi machine drive, it can achieve power balance automatically by the master-slave control.  
4,Realize the real maintenance free by getting rid of the reducer,mechanical soft starting devices and other intermediate link.
5,The motor speed and other technical parameters can be designed separately according to the user needs.

Three, Permanent-magnet Motor VS Traditional Motor
Compared with traditional drive system, reduction box and hydraulic coupling(CST or other mechanical soft-start devices) can be removed; with Intelligent permanent-magnet synchronous direct-drive motor, 20% energy can be saved!
