Description

Controlled mechanical motion is vital for many useful applications in technology. For many of these applications, linear motors have advantages over traditional rotating motors. In this work, we have built a permanent magnet linear motor to test and measure energy efficiency. We find a maximum 30% total energy efficiency and 79% energy transfer rate. In addition, a C-shape support structure is added to the moving part in order to increase the moving accuracy. The test shows that, with the support structure, the fluctuation on vertical direction decreases significantly, but the friction of the system increases a bit.
