Permanent magnet motor PMSM

Starting from the MD-CX magnetic drive range Simaco has decided to introduce alongside the asynchronous motors with a very competitive alternative for performance, energy saving, interconnection, dimensions: the Permanent Magnet Synchronous Motors (PMSM). The advantages of this choice are illustrated below. Greater efficiency of PMSM motors In recent years, great emphasis has been given to improvements in the efficiency of electric motors, also due to changes in regulations that have catalyzed the attention of both manufacturers and customers. Synchronous motors with permanent magnets PMSM offer significantly higher efficiency compared to induction motors, even under partial load conditions, and high efficiency in nominal working conditions. Their construction architecture reduces the thermal losses from the rotor by 100%, the total losses by about 25% and increases the total efficiency by at least 10%. These improvements translate into a lower total cost of ownership, a reduction in CO2 emissions and continuous savings that amortize future increases in energy costs. Costs reduction and energy saving The improvements in terms of technology and efficiency imply a higher initial purchase cost, which is quickly recovered, however, during the operating life of the PMSM motor. However, it is known that 96% of the costs for the entire life cycle of an electric motor have to do with energy consumption during the work phase, and not with the initial investment for the purchase.
