Product Description


As a permanent magnet synchronous motor that is developed by Hiest for air pumps of NEVs based on the operation requirements of air compressor,the electric blast pump (also known as electric air compressor unit) of NEVs can provide gas source required for gas braking, gasbag lifting and pneumatic door opening/closing of electric buses and trucks.It is a core part of electric gas pump for electric bus.

Featured by simple structure,small size,reliable performance, energy conservation,long life and high efficiency,optimization and simulation design,the series product can reach energy-saving efficiency for over 10% compared with the rivals,to extend the cruising ability of electric bus and increase the service life of batteries.

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:

  • 和创
    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.
  • 和创
    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.
  • 和创
    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
