High Quality Low Price Electric AC Synchronous Motor High Power Factor Nov 02, 2017

1, because the magnetic field of permanent magnet synchronous motor is produced by permanent magnet, High Quality Low Price Electric AC Synchronous Motor it avoids the excitation loss caused by the excitation current to produce magnetic field.

2. Compared with asynchronous motor, High Quality Low Price Electric AC Synchronous Motor the efficiency of PMSM is much higher when it is light load, which is the biggest advantage of PMSM in energy saving compared with asynchronous motor. Since usually the motor is in the drive load, High Quality Low Price Electric AC Synchronous Motor very few cases are running at full power, this is because: on the one hand, the user in the motor selection is generally based on the limit of load conditions to determine the power of the motor, and the limit of the opportunity to appear is very small, at the same time to prevent the induction of motor combustion, High Quality Low Price Electric AC Synchronous Motor the user will also give the motor power margin; Designers in the design of the motor, in order to ensure the reliability of the motor, usually in the user requirements of the power base on the further leave a certain amount of power, which results in the actual operation of the motor more than 90% of the rated power under 70%, High Quality Low Price Electric AC Synchronous Motor especially the driving fan or pump load. This causes the motor to work normally in the light load area. For induction motor, its efficiency is very low when light load, while the permanent magnet synchronous motor can maintain high efficiency in the light load.

3, because of the high power factor of permanent magnet synchronous motor, compared with the asynchronous motor, the current is smaller, the stator copper consumption of the corresponding motor is smaller and the efficiency is higher.

4, the system efficiency is high, permanent magnet motor parameters, High Quality Low Price Electric AC Synchronous Motor especially the power factor, is not affected by the number of motor poles, so it is easy to design a multipolar motor, so for the traditional need to drive through the gearbox to the load motor, can be made with permanent magnet synchronous motor drive system, thus eliminating the gearbox, High Quality Low Price Electric AC Synchronous Motor improve transmission efficiency.

As the permanent magnet synchronous motor is designed, High Quality Low Price Electric AC Synchronous Motor its power factor can be adjusted, and can even be designed to 1, and the motor pole number is irrelevant, and the induction motor due to the characteristics of its own excitation, with the increase in the number of Poles, will inevitably lead to lower power factor, such as 8-pole motor, power factor is usually about 0.85, motor power factor

1, high power factor, small motor current, High Quality Low Price Electric AC Synchronous Motor low copper consumption of motor stator, more energy-saving

2, high power factor, motor matching power supply capacity can be lower, while other ancillary facilities such as switches, cables can be smaller, the corresponding cost lower

3, Permanent magnet synchronous motor power factor is not affected by the number of motor poles, High Quality Low Price Electric AC Synchronous Motor in the case of motor matching system permitting, the number of motors can be designed to a higher, the corresponding motor volume is smaller, the direct material cost of motor is lower
