Description
Overmoulding plastic insulation of rotor or stator stacks with straight or slanted poles and with or without compensation Thin-wall insulation · Sigmasoft software for simulations · In-house tool design and manufacturing · 100% insulation quality testing · Linked stamping and injection moulding technologies
Applications
- This technology is used for products in the automotive,
- HVAC and
- garden power tool industries.
- EC motors are used in all three areas.
Technical characteristics
Overmoulding insulation of stator stacks with straight or slanted poles and with or without compensation (PA, PBT, PET etc.)
• Sigmasoft injection moulding simulation
• This technology also enables high-quality and reliable insulation for high-voltage applications
• Excellent thermal conductivity, with greater design freedom for high voltage and media resistance
• Two different heights of overmoulded stack – one tool
• Tools are designed and produced in-house
Advantages
- Only one tool for complete rotor or stator insulation (between the poles as well as top and bottom)
- Improved thermal conductivity
- Simplified motor winding
- Cost efficiency
