The difference between permanent magnet motor and ordinary motor
Permanent magnet synchronous motor uses permanent magnet to provide excitation, which makes the motor structure simpler, reduces the processing and assembly costs, and eliminates the collector ring and brushes that are prone to problems, improving the reliability of motor operation; because no ex...Read More -
Understanding Aperture Sweep During Motor Operation: Causes and Consequences
Porosity excursion is a serious phenomenon that can severely impact the performance and life of an electric motor. It refers to the unwanted movement of air or other material through the motor pores, which can cause a variety of operating problems. Understanding the causes of porosity excursion i...Read More -
What is a composite explosion-proof motor?
Safety is of paramount importance in industrial settings, especially in environments prone to explosions where flammable gases or combustible dusts are present. To address these safety issues, engineers and manufacturers have developed specialized equipment, including compound explosion-proof mot...Read More -
What kind of motor is considered a good motor?
The quality of an electric motor is dependent upon its physical composition and performance indicators. The production process for three phase induction motors incorporates a number of key components, including magnets, cores, coils, bases, Hall sensors, insulating varnish, phase lines and so for...Read More -
The influence of bearing clearance on motor performance
Bearing clearance, often referred to simply as backlash, plays a critical role in the performance and life of an electric motor. The term describes the space between a bearing and the shaft it supports. While it may seem like a small detail, the impact of bearing clearance is significant, affecti...Read More -
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 ...Read More -
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 -
Why are permanent magnet synchronous motors more efficient?
Permanent magnet synchronous motors (PMMs) have gained widespread attention in various applications due to their superior efficiency compared to conventional three phase asynchronous induction motors. One of the key factors for the improved efficiency lies in the unique operating characteristics ...Read More -
How is the axial force of a three-phase AC motor formed?
It has been observed that customers may experience issues with shaft drift or bearing temperature rise due to axial force, regardless of whether the motor in question is high-voltage or low-voltage electric induction ac motor. The optimal operational state of the motor is to ensure the ideal rela...Read More -
What is permanent magnet motor? How is it different from the ordinary electric motor?
—The question thus arises as to what is meant by the term ‘permanent magnet motor’. In what ways does it diverge from the conventional motor? A permanent magnet AC motor (PMM) is defined as an electric motor that utilizes the intrinsic magnetic properties of permanent magnets ...Read More
