Thermal protection limits are equally important as mechanical specifications when designing
electric drivetrains. However, properties of motor drives like mass/length of copper winding …

The proposed paper presents a method to optimally select components of a drivetrain for an
electrically actuated machine. A simple mathematical model of the machine is established …

Selection of components of electric drivetrains is not only based on evaluating their ability to
perform according to mechanical specifications, but-what is equally important-on assessing …

Energy efficiency improvement is the main target of many recent studies in various domains,
especially for electrical drives which constitute the core of industrial applications. The …

A typical challenge for electric drivetrains is to reduce the number of sensors required for
control action or system monitoring. This is particularly important for electric motors …

The simulation of induction motors is based on static and dynamic models that allow the
study of their mechanical performances, as well as their power consumption and losses. The …

Current drivetrain design procedures for electric actuation systems operating in offshore
conditions typically consider two major requirements: to provide sufficient steady-state and …

One of the main design objectives for electric drivetrains operating in offshore drilling
equipment is to keep them as small, yet as effective, as possible, to minimize space they …
