YMKQ (air-to-air cooling) and YMSQ (air-to-water cooling) high starting torque asynchronous high-voltage motors are the auxiliary motors for coal mills independently developed by the company. The motors meet the driving needs of coal mills and comply with "JB/T 7128 Three-phase asynchronous motors for YTM, YHP, YMPS series coal pulverizers are required by the standard requirements in "Technical Conditions", which can ensure the coal pulverizers to start with load at any time and self-start at 65% of the rated voltage after the power is restarted. Measures to prevent the phenomenon of opening welding and cage breaking of asynchronous motor cage bars.
 
 
 
 
 
   2. Technical characteristics
 
   High-voltage asynchronous motors, especially motors used to drive coal mills and powder exhaust fan equipment, have a large load and frequent starting. When ordinary motors are used, the starting time is long and rotor failures occur frequently, which affects the normal operation of the equipment. The high starting torque motor started in the design and manufacturing process, effectively shortening the starting time, successfully solved the failure of the motor rotor, such as open welding, broken cage, etc., and won the approval of the same industry and users. The first motor of this series ran in 1989 and won the praise of users. Among them, the 450kW motor won the third prize of National Science and Technology Progress Award in 1997. This series of motors is the first choice for supporting motors for coal mills, and can also be used as drive motors for heavy-duty equipment in metallurgy, chemical, mining, and building materials industries.
 
   According to the actual operating conditions of this model of motor, the starting recorder test was done. The total weight of the starting equipment is about 90t, the starting is only 1.08s, and the starting current is 6.3 times. The MS curve of the motor was admitted by Tsinghua University. The curve showed that the starting torque was 3.52 times, the maximum torque was 3.64 times, and the minimum torque was 3.32 times. The following conclusions were made: the motor torque-speed characteristic curve is flat, starting Torque, maximum torque and minimum torque are all higher than 3 times, starting time is short, starting performance and overload capacity are all excellent, especially suitable for mechanical equipment with high starting torque and overload capacity.
