DESCRIPTION
The system can be applied to both round and rectangular magnet wire and supports different types of insulation materials, including enamel coatings such as PI and PAI as well as high-performance polymers like PEEK and PFA. This testing process is essential to ensure the quality of magnet wire used for stator and rotor windings, helping to prevent insulation failures, malfunctions, and short circuits in electric machines.
The HVT24 cabinet can manage up to 24 controllers (HVTC), allowing parallel testing across multiple production lines. Each controller can be connected to up to three insulation testers (HVTT) equipped with dedicated wire contact systems using pulleys or brushes.
The system can receive an encoder signal from the production line, enabling it to generate output signals indicating the presence of insulation defects together with their precise position along the wire.
Controllers can also interface with Marposs Aeroel dimensional gauges, allowing dimensional measurement data to be acquired and stored together with the insulation test results.
