Bakelite’s Molding Compounds for Commutator Applications
For automotive, household and industrial applications Bakelite® thermoset molding compounds are utilized when there must be a combination of:
- Good electrical insulating properties and high heat resistance
- Rigidity, surface hardness
- High elastic modulus and
- Good solvent resistance
Very small amounts of molding compound must not only provide electrical insulation but also anchor the copper lamella and ensure optimal seating of the lamella on the rotor axis at high rotational speeds, even under sever thermal stress.
From washing machine motors to fan and wiper drives, if the recommended operating temperature range is temporarily exceeded, dimensional stability will be maintained.
