Details


The low-speed and high-torque variable frequency permanent magnet drive system (VDS) takes advantage of the low-speed and high-torque advantages of the permanent magnet motor, and the system optimizes and combines the respective structures and performances of the permanent magnet motor, reducer and frequency converter. The permanent magnet motor adopts concentrated winding, optimal pole-slot matching, patented rotor structure, less leakage flux, large main flux, and achieves higher efficiency (up to 97%) and power factor (up to 0.99). The torque amplifier coupled with the permanent magnet motor has the characteristics of increasing the output torque and matching the load inertia. Under the control of the inverter, the characteristics of the permanent magnet motor can be optimized, and the power between the motors can be easily realized when the multi-machine is linked. balance.

The permanent magnet motor rotor adopts permanent magnet material excitation, which realizes low-speed and high-torque power transmission, and has higher efficiency and higher power factor.

● The inverter is used to control the motor, which can directly drive the conveyor

● The system has large starting torque, strong overload capacity, and intelligent speed regulation function, which can meet the needs of users at any time according to the production flexibility such as load changes and output adjustment.

● The motor is powered by a frequency converter, which has a wide range of speed regulation and high operating efficiency.

● Variable frequency soft start, small starting current, basically no impact on the power grid

● Eliminate the mechanical transmission equipment in the middle, simplify the transmission chain, reduce the failure points and reduce the probability of failure while basically eliminating the loss in the transmission process, thereby reducing the maintenance cost and basically realizing maintenance-free

●Compact structure, small size, light weight, easy installation and space saving

● Energy saving and material saving, beneficial to the country and the people, and cost-effective products

● This series of motors can be used in most low-speed direct drive applications, and are suitable for various power transmission places, such as coal mines, ports, mines, power plants, steel and other related fields. Among them, the explosion-proof VDS for mining uses high-strength explosion-proof structure for its control cabinet, frequency converter and motor. Equipment protected by explosion-proof enclosure "d"", the explosion-proof mark is "Exd1Mb". It is suitable for electric drive of mechanical equipment in coal mines and underground explosive gas environments.
