To date, permanent magnet motors have not been widely used in many industrial applications as they require additional speed or position sensing mechanisms and control by high end drive units, making them relatively costly and complicated to install. As a result, even though they are less efficient and considerably larger in size, induction motors have generally been the preferred choice for design and production engineers.
Now, however, by using innovative algorithm control based on motor voltage and current output, the new AC650S Drive enables standard permanent magnet motors to be used in closed loop applications, without the need for additional sensors. Engineers can therefore benefit from the energy savings that can be achieved from brushless motor such as Parker’s NX and ATEX EX Series, with savings of up to 12% for a 0.75kW system being possible; similarly, engineers have the opportunity to design more compact control systems, which can be as small as 25% the size of a conventional induction motor assembly.
