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)

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 on the key structure of

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)
