- Abstract
- A directly cooled winding in an electrical machine
is an appealing solution for a traction application when the
electrical machine is operating near peak power for extended
periods of time. This directly cooled winding is based on a
laminated structure where the power losses in the conducting
strips are instantly dissipated by an air-flow between the strips.
As an outcome, the hottest component of the electrical machine –
the windings are directly cooled, which in turn improves the
thermal management of electrical machines, boost up their peak
torque and power, reduces their size and suits them better for the
specific application. This paper focuses... (More) - A directly cooled winding in an electrical machine

the machine construction – a direct air cooled laminated winding
segment for a PMSM with distributed concentrated windings.
The AC losses and heat transfer of the laminated windings are
presented with production experiences on winding segments. (Less)
