    • The centrifugal pump adopts brushless motor
    • The reasons for the long life of brushless motors can be summarized as follows:Structural features:
      The rotor of the brushless motor and the brush are not in contact, and this design avoids the friction and wear between the brush and the rotor in the traditional brush motor, thus significantly improving the life of the motor.
      Durability:
      The brushless motor has the characteristics of no carbon brush, low friction, no spark, no electromagnetic interference, etc., which makes it more durable than the brushed motor. These characteristics make the brushless motor more stable during operation, reducing the loss caused by friction, sparks, etc.
      Analysis of influencing factors:
      The life of brushless motor is mainly affected by bearing life, insulation life, temperature and load. However, due to the structural advantages of brushless motors, these factors have relatively little impact on their life.
      Bearing life: Although the life of the bearing has an impact on the life of the motor, the design of the brushless motor usually ensures stable operation of the bearing for a longer period of time.
      Insulation life: The coil inside the brushless motor has good insulation performance, reducing the motor damage caused by arc discharge and short circuit.
      Temperature: Although too high a temperature can cause damage to the material inside the motor, the brushless motor usually maintains good heat dissipation performance during design and operation, reducing the risk of overheating.
      Load: The brushless motor has good stability and reliability when bearing the load, reducing the motor damage caused by overload operation.
      Service life data:
      According to different sources of information, the design life of brushless motors is generally up to 20 years, but the actual service life varies depending on the conditions of use and the environment. In general, the life of brushless motors can reach tens of thousands of hours or hundreds of thousands of hours. For example, it is pointed out that the brushless motor can work continuously for about 20,000 hours, and the conventional service life is 7-10 years.
