Coil cooling device for a linear motor

A coil cooling device for an ironless linear motor, comprising:

• a cooling plate folded and thereby forming two plate parts opposite to each other, each plate part comprising grooves;
• cover plates fixed against the plate parts of the cooling plate to form with the grooves one or more fluid channels of two distinct cooling circuits, each cover plate comprising at least one inlet aperture and at least one outlet aperture in fluid communication with the one or more fluid channels of a respective cooling circuit of the two distinct cooling circuits, wherein the cover plates are facing each other to form together a coil compartment;
• a manifold comprising an inlet port and an outlet port in fluid communication, respectively, with the at least one inlet aperture and the at least one outlet aperture of respective cover plates;
• and
• a coil unit comprising a coil support arranged to receive coils of the ironless linear motor, and configured to be mounted inside the coil compartment such that opposite sides of the coils are arranged to be cooled by a respective cooling circuit of the two distinct cooling circuits.
