Suppressing Bearing Voltage in an Inverter-Fed Ungrounded Brushless DC Motor
IEEE Transactions on Industrial Electronics, 2013This paper describes the bearing voltage reduction achieved by the brushless dc motor for air conditioning driven by the voltage source inverter. First, the simplified equivalent circuit of the brushless dc motor is derived based on the common-mode equivalent circuit where stray capacitance is taken into account.

In this paper, we propose a method to suppress shaft voltage by changing the shape of the permanent magnets in the Interior Permanent Magnet (IPM)-type high voltage motors. The shaft voltage, which is induced by parasitic components and leakage flux in the motor driven system, adversely affects their bearings. For minimizing the shaft voltage, a magnet

Exact linearization of a voltage-controlled 3-pole active magnetic bearing system
IEEE Transactions on Control Systems Technology, 2002Most magnetic radial bearings adopt the configuration of eight magnetic poles. Such a configuration usually requires four power amplifiers and has high power loss, resulting in high cost. In this study, a 3-pole active magnetic bearing (AMB) is investigated, which requires only two power amplifiers. In addition, it has lower power loss.
