1. Summary

TS2000 is a device specially used to measure the magnetostriction coefficient of electrical steel sheets in the magnetization direction during the AC magnetization process. The device consists of excitation and measurement devices, single sheet tester, pressure loading device (optional), laser vibrometer, air-floating shock-absorbing platform, automatic loading and unloading device (optional), protective cover, industrial control system and special test software.

This system can measure the magnetostriction coefficient λ, specific total loss Ps, specific apparent power Ss, magnetic polarization Jm, magnetic field strength Hm, amplitude magnetic permeability μ_a and other magnetic parameters of electrical steel under conditions such as different frequencies, magnetic field strengths, magnetic polarization strengths (or magnetic flux density), harmonics (optional), no stress or applied compressive stress (optional). , suitable for research and development and quality testing of electrical steel. Reference standard: IEC 60404-17.

5.1 Parameters

Note: ① The specific values of B and J depend on material properties 

5.2 Typical Measured Parameters

Test Conditions:

• H, B, J at a measurement frequency of 50 Hz / 60 Hz, under stress-free conditions

• For grain-oriented silicon steel: 1.7 T; for non-oriented silicon steel: 1.5 T, under stress-free conditions

• Regarding accuracy of measured values: Depending on the method and position of the specimen in the measurement frame, a deviation of 1% to 2% may occur.

• Regarding repeatability of measured values: For the same specimen, without considering its temperature characteristics, after placing the specimen in the specified position and keeping it stationary, repeated measurements are performed. The resulting (repeatability data) is regarded as the repeatability of the specimen and is related to the performance of the specimen under test.

• Repeatability = the larger of the two values calculated as:

      ( |maximum value – average value| ) / average value

      ( |minimum value – average value| ) / average value
