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...Read More -
Why does the electric motor vibrate when it is started or powered off?
For three phase asynchronous electric motors, the start-up process is a critical stage that significantly affects performance and service life. Two common methods of starting electric motors are voltage modulation and frequency modulation. These techniques help create a more balanced starting pro...Read More -
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...Read More -
