Diagnosis of Mechanical Faults in Electric Motors

The ability to monitor the condition of an electrical machine has been a concern of industry for many years. Knowing when a machine requires maintenance allows users to perform the required maintenance at their convenience, rather than during costly unscheduled shutdowns. This need for improved industrial monitoring techniques has produced a number of studies on the detection of mechanical faul...

Reference frames for simulation of electric motors and drives

Simulations of AC electric machines are usually performed in a coordinate system, or reference frame, with two axes (often denoted by d and q, or represented as a complex space vector). A third axis, the zero-sequence axis, is a homopolar axis that is necessary for handling certain unbalanced conditions. Historically, the transformation was essential to getting reasonable results, since computa...

A Power Presizing Methodology for Electric Vehicle Traction Motors

This paper proposes a methodology for presizing the power of an electric vehicle traction motor. Based on the vehicle desired performances, the electric motor optimal power can be calculated. The final objective is to meet the design constraints with minimum power under the European urban (ECE-15) and sub-urban (EUDC) driving cycles. The power presizing methodology is validated through extensiv...
