RIMAC, an Italian machinery manufacturer, has been delivering advanced technology for electric motor production to the global market since 1985.
Advanced rotor banding machines
One of RIMAC core areas of expertise is rotor winding technology: the company provides advanced automatic rotor banding machines designed to precisely wind pre-preg tapes onto the external surface of rotors with exceptional accuracy and pre-tension.
RIMAC banding technology has evolved into a range of specialized product lines, including Banding Machines for Permanent Magnet Rotors (both IPM and SPM configurations). Rotor banding is essential in motors with surface magnets or embedded magnets in laminated stacks, particularly those designed for high-speed operation and lightweight configuration. This process ensures the secure positioning of magnets and/or sections of the laminated stacks under maximum rotational speeds or extreme accelerations, effectively counteracting centrifugal forces and contributing to the motor’s overall stability and performance.
Integrated laser technology
Building on this expertise, RIMAC now introduces a groundbreaking new PM Rotor Banding Machine that goes beyond the traditional application of thermoset tapes. In fact, this advanced solution is also capable of applying thermoplastic tapes, enabled by an integrated laser technology that allows for in-situ curing during the winding process. This unique feature offers manufacturers increased flexibility, as they can select between thermoset or thermoplastic tapes based on specific performance needs, thus once again pushing the maximum performance limits achievable by permanent magnet motors even further.
RIMAC new machine incorporates the trusted features that have long defined their banding technology: advanced tape tensioning system capable of achieving maximum tension with any pre-preg tape on the market, highly accurate and stable tension control, precise tape placement management, advanced software with monitoring systems to oversee the banding process and collect production data, the possibility for a fully automated process powered by RIMAC cutting-edge technology. These elements continue to make RIMAC a preferred choice among leading PM motor manufacturers worldwide, ensuring accurate and consistent banding results.
With its latest innovation – the introduction of laser-enabled thermoplastic tape application – RIMAC once again leads the way in banding technology for Permanent Magnet Rotors, introducing a machine that delivers performance not previously attained in the industry, unparalleled versatility and exceptional efficiency to the high-performance motor industry, thus pushing the boundaries of innovation.
