Being more efficient does not automatically have to mean being bigger. The new m200-P and m500-P three-phase AC motors from Lenze achieve the premium IE3 efficiency class in accordance with IEC60034-30 without any jumps in size compared with the IE2 efficiency class. For “simple” mains operation with fixed speeds, the m200-P motors will provide a power range between 5.5 and 45 kW with a variety of voltages. The m500-P motors cover the same power range. They are optimised for use with frequency inverters, but can also be operated straight from the mains.
Compared with the IE2 class, the two new ranges reduce the amount of energy lost – and therefore also reduce the energy costs – by up to 20 per cent. This is why investments in this economical drive technology pay for themselves in most cases within the first two years, especially because Lenze also offers two gearbox ranges with high efficiency levels, the GnG and the g500. Making an early change from IE2 to IE3 is made easy by the fact that the axis height remains the same and construction changes are therefore unnecessary in most cases.
The new ranges come with precisely coordinated electrical interfaces and a wide variety of options such as brakes, encoders and blowers. Thanks to the optionally available certification from UL, CSA and CCC, and to the IE3 efficiency class, which is mandatory in some markets, the m500-P motors can be used almost anywhere in the world.
