Abstract
This article compares the single- and double-coil-based active magnetic bearing (AMB) for high-speed application. Present days high-speed rotating machines have vast applications for domestic and industrial purposes. Magnetic bearing supports the load using levitation, which means contact friction is zero, so losses will be very less, and supports very high rpm. This manuscript contains the design of single- and double-coil I-type actuators, magnetic analysis using finite element-based software, simulation, experimental verification, and the high-speed test comparison between the designed systems. The magnetic analysis is performed in ANSYS Maxwell software according to the design data; similarly, simulation is also done in Multisim. After getting the required magnetic analysis data and simulation data, both the AMB designs are implemented in hardware, and the results are compared. For the high-speed test minimum, 10 V and a maximum of 100 V are applied to both AMB rotational systems and a maximum 22425 rpm speed is observed in the tachometer.
