product details

A. Characteristics of permanent magnet bearings

1. Permanent magnet bearings are a type of support that support the load or suspension rotor by the magnetic field force of a permanent magnet.

2. Achieve high-speed operation, up to 100,000 r / min, the speed is limited only by the shaft material.

3. There is no direct contact and friction between the shaft and the support, and no heat is generated.

4. High precision, can reach sub-micron level.

5. Low power consumption, only 10% of ordinary bearings.

6. Can keep running in harsh environment, deep cold and vacuum environment.

7. Due to reducing the moment of inertia, the speed of the hoisting motor is increased by 20% compared with the same level.

8. The bearings do not need to be lubricated, and there is no trouble of oiling on time.

9. Can realize closed design, no dust inside.

10. The rotation speed is less than 3500r / min, and the constant temperature is maintained at 32-41 degrees.

11. Requires high operating conditions, magnetic interference to the environment, but no other pollution.

two. Notes on designing permanent magnet bearings

1. Under the same conditions, the efficiency of suction bearings is higher than that of thrust magnetic bearings.

2. Permanent magnet bearings can only be designed as passive bearings.

3. Passive bearings cannot be stable in all three directions, and have at least one outline support.

4. Pure permanent magnet bearings can only be five-degree-of-freedom controlled bearings.

5. The operating temperature of permanent magnet bearings is limited by the Curie point of the material itself.

6. Permanent magnet materials are brittle and cannot be impacted or impacted during installation and use.

7. The outer ring of the high speed permanent magnet bearing should be equipped with a fastening ring to prevent direct collision under abnormal conditions.

three. Load direction

Full magnetic levitation is achieved only in the axial direction and can withstand bidirectional axial forces. Additional support is required in the radial direction.

four. Specify when ordering

Axial force, working speed, external dimensions, operating temperature.

Fives. Magnetic bearing size

The external dimensions of magnetic bearings have been serialized, as shown in the table below. We also accept non-standard size magnetic bearings.

Six. Axial magnetic suspension bearing size series
