Soken DAC-LST-3 - Lamination Stator Tester
DAC-LST-3 is designed for a pass/fail judgment test of lamination stators of motors by comparison with a reference (*).
A built-in exciting source gives B (Magnetic Flux Density) and H (Magnetizing Force) to read W (Iron Loss). PWM inverter being introduced for the source, DAC-LST-3 is smaller than the last passive transformer type.
Moreover as in all-in one type, no external stabilizing source is necessary. The frequency is changeable in the range of 50Hz to 400Hz.
A USB interface is provided as standard, and data acquisition and transmission from a PC is possible.
(*)The reference stator shall be sampled from your product and preset on the tester.
Test Specimen
- Lamination Stator-Core of Motor
Judgement Mode & LCD Display
Magnetic Flux Density: *.** mT
Magnetic Field Strength: *.** A/m
Core Less *.*** mW/kg
LEVEL: 0.00%
FREQUENCY: 50Hz
AUTO MEAS.: Off
INTERFACE: INT TOOL
MODE Selectrion
B-MODE: Fix B value, and measure H and W.
H-MODE: Fix H value, and measure B and W.
Judgment measurement can be performed by comparing a reference value input in the tester.
Example:
When B-MODE, input an optional value of Magnetic flux density (B), and set upper limit values of both Magnetic field strength (H) and Core loss (W). When measured value is within the limit, indication lamp lights in green, if less than the limit, the lamp lights in yellow.
Size of Stator
When measure a stator like Fig 1, Magnetic Path length, Lamination Height and Magnetic width must be set as follows.
| L = (ℓ1 + ℓ2) * π /2 | :Setting of LENGTH |
| T = t | :Setting of THICHNESS |
| W =ω | :Setting of WIDTH (at the narrowest part) |
- Magnetic characteristic (B-H-W) can be judged by easy operation, and management of quality of stator cores is possible.
- The frequency of the exciting power supply in range of 50 Hz to 400 Hz.
- Adjustment of the exciting power supply can be performed smoothly.
- Judgment result with a preset value and a measurement value is displayed intelligibly on a LCD panel.
- Acquisition of measuring data and transmission of preset values from a PC is possible by using USB interface.
