The TBW series is a variant of the TB series with water cooling. Its feature is a fully integrated and highly effective cooling system that enables this series of motors to achieve higher continuous thrust than standard versions, while maintaining sub micron positioning accuracy and withstanding extreme acceleration. Because heat does not dissipate into mechanical structures, it is particularly suitable for applications with heat dissipation issues.
