  • Why does the motor winding temperature rise fail?

    The performance and life of an electric motor are significantly affected by its operating temperature. One of the key factors leading to unqualified motor winding temperature rise is the interaction between stator current and stator copper losses. When the stator current increases, copper losses ...

  • What are the differences in rated current and torque between motors with the same power?

    It should be noted that the speed of electric motors with the same power may vary significantly depending on the application conditions or supporting equipment. By way of illustration, the 2P and 8P motors in the industrial electric ac motor have a synchronous speed of 3000 rpm for the 2-pole mot...

  • What should I pay attention to when installing PT100 on the electric motor?

    Both PTC and PT100 (temperature sensors PT100 for windings & Bearings)are two most-commonly utilized temperature-measuring elements in the context of motor product temperature testing. In contrast, PTC can be conceptualized as a temperature-activated switching element, whereas PT100 is a soph...
