Magnet Wire Elongation Tester

The NOVA 112 Magnet Wire Elongation Tester performs the elongation test according to NEMA, or IEC and JIS specifications. The tester can be calibrated traceable to N.I.S.T. The elongation tester elongates a specimen of annealed magnet wire with a test length of 10 inches (25.4 cm) to a predetermined % elongation up to 50% or to failure. The maximum elongation is 50 %. A laser engraved scale is used to indicate the percent elongation.
The tester can test wire sizes 44 AWG to 12 AWG (0.05 mm to 2 mm).
Ball screw and linear guide assembly together with reliable electronics in a totally enclosed chassis provide a sturdy and reliable test platform.

Nova 215 LSE Tester

The NOVA 215 Low Stress Elongation (LSE) Tester performs the low stress elongation test according to ASTM D-1676 for magnet wire and B-279 for un-insulated wire. The tester can be calibrated traceable to N.I.S.T. For copper conductor, the tester applies an initial load of 7,500 psi (51,713 KPa) and a final load of 15,000 psi (103,425 KPa) to a 10-inch (25.4cm) specimen of round wire. The final load is maintained for 30 seconds and the load is then returned back to the initial load. The low stress elongation (LSE) value is then automatically calculated and displayed after the loading was removed and the test completed. Aluminum wire can also be tested.
LSE value, with reference to the wire diameter, helps to identify the state of the softness (formability) of the wire. A larger LSE value indicates that the wire has greater formability and is better able to absorb bends and twists during motor and coil winding operation. Low LSE value (with reference to the same wire diameter) indicates harder wire with more springiness.
High precision digital electronic scale and load cell are used to measure the elongation and tension. The load cell has a built-in safety overload feature. The custom designed wire holding jaws are user friendly and require minimal effort in clamping the test specimen.

Nova 300 Pneumatic Snap Elongation Tester

The Nova 300 Pneumatic Snap Elongation Tester performs the “Sudden jerk” elongation test to NEMA or IEC and JIS specifications. The tester uses compressed air to push the piston and “snap elongate” the 10-inch (25.4cm) long wire specimen to the desired percent elongation at 12-15 feet/second (3.66 m/sec to 4.57 m/sec).
The test determines the adhesion characteristics of the magnet wire insulation to the conductor. The percent elongation is easily adjustable from 5% to 50% at 1% increments. The moving jaw is set to the desired ‘snap elongation’ speed through the valve assembly. The valve assembly ensures a consistent and repeatable test. A series of pneumatic valves and a polycarbonate safety shield protects the operator.
