STYB/FTYB series mining explosion-proof three-phase permanent magnet synchronous motorized pulley
Product description
This motorized pulley takes advantage of the fact that permanent magnet motors can be designed in a multi-pole configuration to integrate the drive pulley of the conveyor with the permanent magnet motor, and is designed as an external rotor and internal stator drive unit. The permanent magnet synchronous drum motor system drives the belt directly without any intermediate transmission link, which not only improves the reliability and efficiency of the system, reduces the failure rate and maintenance costs, but also enables a closed loop vector control method to achieve power balance for multiple drives, reducing tape wear and extending the service life of the conveyor.
This series of products are complete with Conformity Certificate Of Explosion-proof and Safety Certificate Of Approval For Mining Products.
Product features
1. eliminates the gearbox and draulic coupling. shortens the transmission chain. no oil leakage and refuelling problems. low mechanical failure rate and high reliability.
2. Customised electromagnetic and structural design according to the equipment. which can directly meet the speed and torque requirements needed by the load;
3. Low starting current and low temperature rise. eliminating the risk of demagnetisation;
4. eliminating the transmission efficiency loss of gearbox and draulic coupling. the system has high efficiency. high efficiency and energy saving. Simple structure. low operating noise and low daily maintenance costs;
5. The use of permanent magnet synchronous drum motor system can solve the problem of “big horse pulling small cart”. that is. to meet the original system requirements of wide load range operation. but also improve the overall efficiency of the system. high efficiency and energy saving;
7. With the vector frequency converter control. The speed range of 0-100% PM motor starting performance is good, stable operation and can reduce the matching factor with the actual load power.
Product Application
The conveyor motorized pulleys are widely used in underground coal mine belt machines.
FAQ
What are the motor nameplate data?
The nameplate of the motor is labeled with important parameters of the motor, including at least the following information: name of manufacturer, motor name, model, protection class, rated power, rated frequency, rated current, rated voltage, rated speed, thermal classification, wiring method, efficiency, power factor, factory number and standard number, etc.
What are the advantages of PM motors over other brands of PM motors?
1.The level of design is not the same
Our company has a professional R & D team of more than 40 people, after 16 years of technical experience accumulation, has a full range of permanent magnet synchronous motor R & D capabilities, according to customer requirements for special design, can meet the needs of a variety of equipment.
2.The materials used are not the same
Our permanent magnet motor rotor permanent magnet material adopts high magnetic energy product and high endowment coercive force sintered NdFeB, conventional grades are N38SH, N38UH, N40UH, N42UH, etc. Our company promises that the annual demagnetization rate of the permanent magnets is not higher than 1‰.
The rotor lamination adopts high specification lamination materials such as 50W470, 50W270, and 35W270, with silicon steel sheets pressed together to reduce losses.
The company’s molded coils all use sintered wire, high voltage resistance to withstand stronger, bulk winding all use corona 200 degrees of electromagnetic wire.
3.Rich in Cases
Our products are used in iron and steel, coal, cement, chemical, petroleum, mining, metallurgy, building materials, rubber, textile, paper, transportation, electric power, medicine, metal calendering, food and beverage, water production and supply and other industrial and mining fields, with a wealth of use cases.
