Magnetic Bearings

The production of magnetic bearings began since 1985. The products can roughly be divided into two classes: Magnetic Thrust Bearing (MTB) and Magnetic Suspension Bearing (MSB). Each of the two kinds consists of two parts that separately contain one permanent magnetic ring. One of the two parts is designed to connect the axis of the disk of the meter, and can rotate along with the disk. The MTB assembly has this part of it fixed on the lower end of the axis. In this assembly, the two magnetic rings have the same magnetic poles face to face, so the magnetic force can push the disk up in the air. However, the MSB assembly has it fixed on the upper end of the axis. In this assembly, the two magnetic rings have the different magnetic poles face to face, so the magnetic force can attract the disk and make it suspend in the air. Because there is a balance existing between the magnetic force and the gravity of the rotating portion of the kilowatt hour meter, when the disk turns around and around, there is no friction. So these kinds of bearing can survive for a long time.

   We have enjoyed rich experiences in producing both American ABB & GE Company's MTB and MSB according to their original drawings and f8 & M8 MTB, which are popular in Chinese traditional kilowatt hour meter market. Besides we have strong ability to design & manufacture various magnetic bearings of special specification according to customer's requirements.

1. Application Range
  The Magnetic Bearing for Kilowatt hour meter is the upgraded product of the jewel bearing, which suits for the use in the single phase and tri-phase kilowatt hour meter. Its operation temperature ranges from -400c ~+800c, and its relative humidity should not exceed 85%(when temperature is 25°c).
2. Installation and Usage
  During the usage of our magnetic bearing, traditional customer should pay close attention to the match between bearing and the base frame and the axis of the disk of the kilowatt hour meter. Especially, concerning the kilowatt hour meter, close attention should be paid to the dimension and tolerance of the connection part between the axis and magnetic bearing. TD3B and XD16.5 is the bearing used in single-phase kilowatt-hour meter, these kinds of bearing are manufactured according to the original drawings of the ABB & GE Company. Because of the dimension of the connection part of the base frame of these products is different with the kilowatt hour meter supplied by Chinese market, if our products want to be used in the Chinese kilowatt hour meter, the base frame must be re-designed. f 8 & M8 MTB can be directly applied in the D86 series and various model emerging before the D86 series without change on the base frame. The key parts of the D86 series are imported from the outside, they can meet the requirements of long life kilowatt-hour meter.
