fully automatic permanent magnet motor assembly
In the classic system concepts for the fully automated production of motors, the magnets are magnetized after they have been placed on the rotor. There are numerous challenges that arise with this concept.
• higher process costs, especially with higher product variance
• pole pitch variations limited by selection of the magnetizing tools
• difficult magnetization of small magnets with short distances
• design limitations for magnet carriers, as these have to fix the magnets by means of a form-fit throughout the process
haprotec has developed and patented a process to be able to place magnetized magnets fully automatically. Our process utilizes the existing magnetic force during the placement process rather than work against it. This technology has clear advantages for rotor production.
• Process stability & -costs - outsourcing the process of magnetization
• Flexibility - cost-effective production of high product variance on one system
• Expansion - cost-effective production expansion of new engine models
• Quality - achieve better quality in end products
• Product Development - more design freedom for magnet carriers through flexible pole spacing across variants and process-safe holding of the magnets without external fixation
Permanentmagnet Bestückung
All processes of the assembly are fully automated. The plasma cleaning of the magnet, the dispensing of the glue, visually checking the adhesive track and then placing the magnet on the rotor.
Optionally, process and plant status data can be collected, visualized and passed on to higher-level MES or trace systems.
The permanent magnets can be assembled on two different machine models. The high-speed system XTS combines flexibility and expandability, while the classic rotary mode can be designed to be more space-efficient.
Depending on the system concept, the machine can also be designed as a stand-alone or inline variant.
The basis for the successful, fully automatic handling of permanent magnets is created by the individual holders for rotors and magnets. Depending on the variance of your products, we can develop different mounts for rotors and magnets to make the assembly as flexible as possible.
The changing of the receiver can be carried out fully automatically or manually.
