RIMAC

Continually growing using electric actuators

The global rise in demand for green energy and the e-mobility revolution in the transport sector have led to the boom in the electric motor market. That is why RIMAC Machines support companies that operate in the global electric motor market, putting their expertise into practice to achieve unparalleled quality standards.

Oil-free fully electrified machine

Situated between the metropolitan city of Milan and the famous lakes of northern Italy, RIMAC offers technical solutions to produce railway and automotive traction motors, electricity generators and highly efficient brushless motors worldwide for over 30 years.

“In recent years, we have worked extensively in the e-mobility sector, as well as the automotive and industrial automation sectors.
As a result of our continued investment in research and development,
we have been able to not only increase our year-on-year growth over the last seven years
but grow the skills and know-how of our dedicated team of professionals”

Francesca Cavallotti, Sales Manager

Why did RIMAC choose Ewellix as a preferred supplier?

The RIMAC teams challenge was to create a machine capable of shaping stator coils for large AC motors (up to 3.5 m). This process required actuators capable of developing high powered density while maintaining accurate movement over several axes. ‘The products offered by Ewellix are much more compact and have considerably higher load capacity’ states Marco Cattaneo, Technical Sales Engineer.

Historically, these machines were equipped with hydraulic actuators: the only technology capable of providing the forces necessary. This technology has several disadvantages, mainly concerning the management and movement of hydraulic pipes in the machine, noise from the hydraulic unit and oil leaks.

‘By using electric actuators supplied by Ewellix, we simplified the assembly phase without the difficulties of hydraulic fluids and oil leaks during assembly. We were also able to eliminate the disruption caused by installing hydraulic pipes and reduce the area needed because of its compact size’.

Developing the new machine using Ewellix’s electric actuators, RIMAC adapted the mechanics to allow electric axes in place of hydraulic ones.
