Reduction of Cycle Time and Increasing Magnetizing Field Strength in Magnetization Process and Production
In a line production of car traction motors the magnetization of the assembled rotor is always a time critical process. Big dimensions combined with deep V-shaped configuration of the magnets inside the rotor require a very high energy of the magnetizing pulse. In consequence there is a high temperature rise after each pulse which only can be eliminated by a long re-cooling time of the magnetizing coil. Parallelization of Magnetizing Coils is one way to cope with fast production rates. However, it requires big invest in equipment.
M-Pulse have optimized the technology by use of multiple synchronized generators which act onto a single coil. This allows less heat and thus shorter cycle times at very little extra invest.
