| On the effects of IGBT drives on traction motor bearings | ||||||
| Author(s) | G. Giannini; L. Fratelli | |||||
| Abstract | High voltage gradients in IGBT drives interact with stray capacitances of the motor and cause: a) overvoltages which stress insulating materials; b) current pulses in bearing, leading to their early wear-out. In the paper phenomena are observed by measurements in the fields, modeled through an equivalent circuit, and SPICE simulated. Efficient design methods to reduce both phenomena are suggested, and their performance is analysed. | |||||
