Why high-speed presses produce axis current controller and Influence
Cause pneumatic presses axis current controller generates
1, the magnetic field asymmetry;
2, the supply current harmonics;
3, pneumatic presses manufacture, installation is not good, since the rotor eccentricity caused by uneven air gap;
4, removable stator core there is a gap between the two semicircle;
5, fan-shaped stator core fight folded sheet number inappropriate choice.
Axis current on the high-speed presses:
High-speed punch-axis current controller or ball bearing surface erosion process dot-shaped pores, the bearing operation deterioration, friction loss and increase heat, eventually leading bearing burned.
