“…Next to the IIBC context, research on EMI behavior and computation of other parasitic effects, such as additional losses, has significantly motivated work on the modeling of i CM and of the HF behavior of the machine. From the myriad of papers on this topic, (Magdun et al, 2007;Mirafzal et al, 2007;Mirafzal, Skibinski, Tallam, 2009;Weens et al, 2009;De Gersem et al, 2010;Zare, 2010) might be taken as examples. Considering the scope of this paper, these findings allow to better take advantage of the modeling techniques of IIBCs themselves, by providing information on one of the most important parameters of influence, the HF CM current i CM .…”

A. Mü tze OVE Today, a search for bearing currents in databases on engineering literature may return hundreds or (depending on the database and any additional filter used) thousands of hits. The degree to which the identified papers address the bearing current topic itself varies. Often, the term is used (as it is common with key words) to reflect the wider context and the topicality of the work that is presented, e.g. a discussion of a new filter topology. Without claiming completeness, this paper provides an overview of the various aspects that have been addressed in literature related to the bearing current topic.Tausende von Treffern: Ü ber umrichterbedingte Lagerströ me, zugehö rige Themen und die Literatur.Eine einfache Suche unter dem Stichwort "Lagerströ me in einer Datenbank fü r Ingenieursliteratur kann zu hunderten oder (abhä ngig von der Datenbank und zusä tzlich verwendeten Filtern) tausenden von Treffern fü hren. Das Ausmaß, mit dem die identifizierten Publikationen das Lagerstromthema behandeln, variiert. Oft wird der Begriff (wie es fü r Stichwö rter ü blich ist) verwendet, um den weiteren Zusammenhang und die Aktualitä t des in der jeweiligen Publikation behandelten Themas, wie z. B. eine neue Filtertopologie, widerzuspiegeln. Dieser Beitrag gibt einen Ü berblick ü ber die verschiedenen mit dem Lagerstromthema in Verbindung stehenden Aspekte, die in der Literatur behandelt werde.

“…III. AC MOTORS STATOR-TO-FRAME STRAY CAPACITANCE The stator-to-frame capacitance at high frequencies in AC motors is a function of motor geometry, and the number of coils directly connected to a motor lead wire [8]. The antiresonance point can be as low as 1 to 2 MHz particularly in large AC motors.…”

“…ANTI-RESONANCE PHENOMENON While the motor anti-resonance point was introduced in a previous work [8], AC motor failure mode due to voltage oscillations at this frequency is the subject of this paper. The test motor used in this investigation, shown in Fig.7, is a 460 V, 7.0 kW PM motor with 72 turns per coil and four coils per phase, which was rewound with four taps per coil.…”

“…Voltage pulses with a short rise-time cause the reflected wave phenomenon in PWM Voltage Source Inverter (VSI)-based motor drives [1][2][3][4][5][6][7][8], which results in high-frequency voltage oscillation at the motor terminals. The frequency of the voltage oscillation increases with decrease in cable length up to a certain frequency and then remains constant at a value that depends on the cable and motor high frequency characteristics.…”

A failure mode for PWM inverter-fed AC motors due to the anti-resonance phenomenon is introduced and investigated in this paper. At high frequencies, an AC motor behaves as a series RLC circuit with a resonance point, so-called antiresonance, typically above 1.0 MHz. If the voltage oscillation frequency, caused by the reflected wave phenomenon matches the motor anti-resonance frequency, an amplified voltage will appear internally between the turns of the stator windings. This externally unobservable state causes winding insulation failure in the AC motor. This phenomenon is experimentally verified using a rewound Permanent Magnet (PM) motor with accessible taps along the stator windings, and the results are presented in this paper.

This work proposes and analyses a model for a cable and permanent magnet synchronous motor to deal with high frequency differential mode components due to IGBT inverter systems. The model permits the study of the differential mode effects separately in the rotor reference frame. The experimental measurements show that the motor differential mode stray capacitances are functions of rotor position. The simulation results of the proposed differential mode circuits, together with the experimental results, show that the level of the differential mode noise currents is of significant value that cannot be ignored. The flow of some differential mode currents in the motor stator windings may contribute to torque pulsations which, require EMI noise filters to be used.
