Many high-end applications, such as in the bio robotics or aerospatial fields, requires highly performance actuators. In the fractional horse power range, the coreless, or slotless, BLDC motor established itself as the most appropriate. This paper presents a technological leap in such motors, allowing to significantly increase their performances. The improvement is made on the windings, which are realized using a flexible printed circuit board, instead of copper wires. Printing the windings on a flexible PCB opens the way to new shape and new topologies of windings, which are not realizable with wire windings, and that allows to increase the torque constant while decreasing the phase resistance. Theoretical considerations, manufacturing process and
experimental results are detailed in this paper.
