Bobbin with Core

Example of Product: Bobbin with Core

  • Bobbins with core are used in modern stepper motors. They are characterised by a very low wall thickness of 0.25 mm in the core area and an extremely high pin retention force of > 50 N.

  • The manufacturing process is fully automatic. In an 8-cavity tool 16 wires are continuously fed from reel, separated and bent. The metal cores are moulded together with the wires. Then the finished moulded parts are sorted and stored by cavities.
