  • 2024-07-23Why is the power supply connected to the stator?
      The characteristics of motor products are the relative stillness of the stator and the relative movement of the rotor during operation. Usually, we use the relatively still parts as the input or output of the power supply. For motor products ...
  • 2024-07-22Why do cast aluminum rotor bars melt and flow out?
      Recently, I shared with you a rotor aluminum flow failure case. The motor showed that the stator and rotor were swept. After disassembly and inspection, it was found that the rotor had serious aluminum flow. It was also due to the aluminum ...
  • 2024-07-19How to prevent the motor shaft from breaking?
      We have conducted many discussions on the causes of broken shafts in combination with failure cases. Reducing and eliminating stress points and eliminating external force factors are the principles for preventing broken shafts. From the pers ...
  • 2024-07-17Select bearings by static load capacity
      Bearing selection is a must for m otor designers . Proper bearing selection can effectively guarantee motor performance. Otherwise, the motor can only grow through continuous failures. Well-known bearing manufacturers will work hard on the ...
  • 2024-07-16What is the reason for the motor vibration?
      In the manufacturing process of the motor , the factors that may cause the motor vibration will be reduced and eliminated through measures such as rotor dynamic balancing, winding insulation treatment, and component matching tolerance adjus ...
  • 2024-07-15Differential protection used on large high-voltage motors?
      Compared with small and medium-sized motors, high-voltage motors are expensive and are used in critical and special applications. Whether it is the disposal of the motor body after a failure or other problems derived from the failure, it may ...
  • 2024-07-12The influence of paint on motor windings on the motor
      For any motor product, the dipping and baking process is a very critical control link. For this process, it is mainly controlled by equipment, technology and process management. The purpose of dipping and baking the motor winding is to fill ...
  • 2024-07-11Why are electromagnetic flat wire motors so popular?
      The winding scheme is the dominant factor of motor products, which directly affects or determines the performance indicators of motor products in many aspects, such as cost, efficiency, temperature rise and insulation level. ...
  • 2024-07-10Why are cast aluminum rotor motors so widely accepted?
      According to the material characteristics of the motor rotor slots, there are wound rotors, cast aluminum rotors and permanent magnet rotors. In comparison, cast aluminum rotors are the most widely used, of course, due to some cost and proce ...
  • 2024-07-09What to consider about the rotor when selecting a VFD?
      For working conditions with continuous speed change requirements, the inverter will be used to drive the motor, that is, the motor speed can be adjusted steplessly by changing the frequency of the motor power supply. ...
