瑞士 IBAG 公司最近开发一种新颍的高频电机,采用磁浮轴承,额定功率52kW,转速为40000r/min。在一对由电磁铁产生的磁场中悬浮着配有磁性轴承的转子,轴承无摩擦,不用润滑,稍有微热。这种转轴的磁铁有一环行电路,轴上装有磁铁、功率放大器、微处理机和传感器。当传感器检测到转轴偏离电磁铁时,微机使电磁铁中的电流强度增加,把转子调整至中心位置。在转轴上有两对磁铁(X 轴和 Y 轴)产生磁 IBAG Switzerland recently developed a new high-frequency motor Ying, the use of magnetic bearings, rated power 52kW, speed 40000r / min. Suspended in a magnetic field generated by the electromagnet with a rotor of a magnetic bearing, the bearing is frictionless, non-lubricated and slightly warm. The magnet of this spindle has a circular circuit with magnets, power amplifiers, microprocessors and sensors. When the sensor detects that the shaft deviates from the electromagnet, the microcomputer increases the current in the electromagnet and adjusts the rotor to the center position. There are two pairs of magnets on the shaft (X-axis and Y-axis) that generate magnetism
