Product Description

By using the ansoft software, Hiest has designed and researched HCTYC specific permanent magnet motor AOI of air compressor and HCTYP permanent magnet variable motors based on the special conditions of air compressor,to satisfy all operation conditions of air compressor.

The special stator and rotor magnetic field can minimize the cogging torque, suppress the high-harmonic magnetic field, in order to satisfy the design indexes of broadband,energy conservation and low noise.It is featured by wide-range and constant-torque power regulation,stable speed regulation and has no torque ripple.

The stator and rotor are made of high-performance low-loss silicon steel sheets,while the rotor magnetic steel is made of high-performance NdFeB permanent magnet material.The ultra-high intrinsic coercive field of permanent magnetic,can ensure higher resistance to demagnetization of permanent magnet,to prevent demagnetization of air compressor when running at high temperature.

Advantages of PMSM

The permanent magnet motor consists of stator, rotor, bearing device, end cover, junction box, fan/fan cover, in which, the stator is a fixed part of motor and consists of one stator core, base and 3-phase field winding. The rotor, as the revolving part of motor, is mounted with permanent magnet poles. Hiest provides customers with a series of standard and customized permanent magnet synchronous motors which have the following characteristics compared with the traditional asynchronous motors:

High efficiency: Efficiency index of HCTY/HCTYP series permanent magnet motor is over 92%, reaches National Class 1 and it is superior than the EU IE4 (motor efficiency level in 2017) standard.
High power factor: As for HCTY/HCTYP series permanent magnet motor rotors, they are free for induced current excitation, while the stator winding has resistive load; the motor has high power factor when it is running between the 1/4 load and rated load. The power factor at rated point is close to 1.
High starting torque: The starting torque of HCTY permanent magnet synchronous motor is about twice that of Type Y/Y2 motor .

Wide range of speed adjustment: The motor speed is strictly in direct proportion with frequency; the variable-frequency speed adjustment accuracy is very high and the width can reach 1:1000, while the asynchronous motor is just 1:100.
Others: Small size, light weight, low material consumption, noise and temperature rise; simple structure and reliable running
