Performance and durability for high-dexterity robot

The OEM engaged Portescap based on its extensive experience in designing motion solutions for robotics. The motion solution designer specified its Athlonix 24DCT brush DC motor and MR2 encoder to meet the OEM’s requirements. Neodymium magnets helped to increase available torque by 20% over the competing motor designs, thanks to the properties of greater magnetic strength, which also enhanced power density. The motor’s coreless design, free from a traditional iron core but instead utilising surrounding permanent magnets, also contributed to a lower mass motion package.

To optimise the lifetime of the motors, Portescap’s solution included constant spring force carbon brushes. This design ensured that regular contact with the commutator would minimise the potential of bounce and increased friction during operation, as well as improving performance with a more consistent electrical connection.
