MWS Wire /
More power in less space.
Microsquare Magnet Wire® is miniature square and rectangular magnet wire for specialty coil and motor windings with tighter dimensional specifications.
When space is at a premium, MWS Microsquare Film-Coated Magnet Wire allows design engineers to create compact coils and smaller motors with a tighter coil configuration than the same amount of round wire.
For the tightest packing of round wires on a multi-layer winding, the wires in the upper layer are tightly wound into the grooves of the lower layer for at least 300 degrees of the coil circumference
MWS Microsquare Magnet Wire® allows for greater efficiency and reduced heat due to the dense packing and improved winding uniformity that reduces air space and enables a higher fill factor.
