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.
he 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.
PMSM motors already meet the requirements of the IE4 and IE5 standard (Super-premium Efficiency), this is demonstrated by their potential energy savings, up to 40% compared to an inverter-controlled squirrel-cage IE2 motor.
The pumps thus made allow the implementation with different sensors (flow, pressure, temperature) in order to create a system able to monitor performance by creating statistics on working hours, faults, maintenance intervals. Finally, the possibility of interconnection of the pump in industry 4.0 system.
