Air Cooled PMAC Motor 0-3000rpm for Industrial Automation

Product Description

Due to the use of a permanent magnet to provide a magnetic field, the rotor process is mature, and reliable, its size flexible, and its design, and power range from dozens of watts to megawatts. At the same time, by increasing or decreasing the number of permanent magnets in the rotor, it is easier to change the number of poles of the motor, so that the speed range of the permanent magnet synchronous motor is comparatively wider. With the use of a multi-pole permanent magnet rotor, the rated speed can be as low as a single digit, which is difficult to achieve by ordinary asynchronous motor.

Especially in the application environment of low speed and high power, a permanent magnet synchronous motor can adopt multi-pole direct drive at low speed. Compared with an ordinary motor plus speed reducer, the advantages of a permanent magnet synchronous motor are prominent.

High-efficiency NdFeB permanent magnet is adopted, with no excitation loss. Special rotor structure design has greatly reduced iron loss and stray loss. The motor efficiency is above IE4 standard, Compared with the three-phase asynchronous motor, the efficiency is improved by 5-10% and the power factor is increased by 10-15%.

High efficiency and high power factor can be maintained in the load range of 20% to 120%. The power factor can be 1, while a three-phase asynchronous motor can only reach 0.86, it effectively reduces the cabling loss and improves the utilization rate of the power grid. Energy saving is more significant under light load.
