This series of products is a direct-drive motor with a rated voltage of 10kV, powered by a frequency converter, which can directly meet the requirements of load speed and torque, eliminating the need for a speed reducer and buffer mechanism in the special drive system, and fundamentally eliminating all kinds of problems that exist in a motor and gear reducer drive system. Safe and reliable, low installation and maintenance costs and other advantages. According to user needs, other voltage levels can be provided. 1. Eliminates the gearbox and hydraulic 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 hydraulic coupling. the system has high efficiency. high efficiency and energy saving. Simple structure. low operating noise and low daily maintenance costs; 5. The rotor part has a special support structure. which enables the bearing to be replaced on site. eliminating the logistics costs required for returning to the factory; 6. Adopting direct drive system of permanent magnet synchronous motor can solve the problem of "big horse pulling small cart". which can meet the requirement of wide load range operation of the original system. and improve the overall efficiency of the system. with high efficiency and energy saving; 7. Adopt vector frequency converter control. speed range 0-100% motor starting performance is good. stable operation. can reduce the matching coefficient with the actual load power. The series products are widely used in various equipments such as ball mills, belt machines, mixers, direct drive oil pumping machines, plunger pumps, cooling tower fans, hoists, etc. in coal mines, mines, metallurgy, electric power, chemical industry, building materials and other industrial and mining enterprises. How are bearings replaced? All permanent magnet synchronous direct-drive motors have a special support structure for the rotor part, and the replacement of bearings on site is the same as that of asynchronous motors. Later bearing replacement and maintenance can save logistics costs, save maintenance time, and better protect the user's production reliability. What are the key points of direct drive motor selection? 1. On-site operating mode: Such as load type, environmental conditions, cooling conditions, etc. 2. Original transmission mechanism composition and parameters: Such as the nameplate parameters of the reducer, interface size, sprocket parameters, such as tooth ratio and shaft hole. 3. Intent to remodel: Specifically whether to do direct drive or semi-direct drive, because the motor speed is too low, you must do closed-loop control, and some inverters do not support closed-loop control. In addition the motor efficiency is lower, while the motor cost is higher, the cost-effective is not high. The enhancement is the advantage of reliability and maintenance-free. If cost and cost-effectiveness are more important, there are some conditions where a semi-direct-drive solution may be appropriate while ensuring reduced maintenance. 4. Controlling demand: Whether the inverter brand is mandatory, whether the closed loop is required, whether the motor to the inverter communication distance should be equipped with an electronic control cabinet, what functions should the electronic control cabinet have, and what communication signals are required for remote DCS.
