1. Eliminate the gearbox and hydraulic coupling. shorten the transmission chain. there is no problem of oil leakage and refuelling. 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. This series of products is a direct-drive motor with a rated voltage of 380V, powered by a frequency converter, which can directly meet the requirements of load speed and torque, eliminating the need for a gearbox and buffer mechanism in the transmission system, and fundamentally overcoming the various disadvantages of the induction motor plus gear reducer transmission system, with high transmission efficiency, good starting torque performance, energy saving, low noise, low vibration, low temperature rise, safe and reliable operation, low installation and maintenance costs, etc, It has the advantages of high transmission efficiency, good starting torque performance, energy saving, low noise, low vibration, low temperature rise, safe and reliable operation and low installation and maintenance costs. Other voltage levels can be supplied according to customer needs.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. What are the motor mounting types? The structure and mounting type designation of the motor is consistent with IEC60034-7-2020. That is, it consists of the capital letter "B" for "IM" for "horizontal installation" or the capital letter "v" for "vertical installation" together with one or two Arabic numerals, e.g.: "IM" for "horizontal installation" or "B" for "vertical installation". "v" with 1 or 2 Arabic numerals, e.g.. "IMB3" denotes two end-cap, footed, shaft-extended, horizontal installations mounted on foundation members. "IMB35" denotes a horizontal mounting with two end caps, feet, shaft extensions, flanges on the end caps, through holes in the flanges, flanges mounted on the shaft extensions, and feet mounted on the base member with the flanges attached. "IMB5" means two end caps, no foot, with shaft extension, end caps with flange, flange with through hole, flange mounted on the shaft extension, mounted on the base member or ancillary equipment with flange "IMV1" means two end caps, no foot, shaft extension to the bottom, end caps with flange, flange with through hole, flange mounted on the shaft extension, mounted on the bottom with flange vertical mounting. "IMV1" stands for vertical mounting with two end caps, no foot, shaft extension downwards, end caps with flanges, flanges with through holes, flanges mounted on the shaft extension, mounted on the bottom by means of flanges. Some of the most commonly used mounting options for low voltage motors are: IMB3, IMB35, IMB5, IMV1, etc. Which method is effective in avoiding galvanic corrosion of bearings? Insulate the shaft, Using insulated bearings, Insulate the end cover and adding carbon brushes.
