COOLING STRUCTURE FOR ELECTROMAGNETIC COIL, AND ELECTROMAGNETIC ACTUATOR

摘要

A cooling structure for a first electromagnetic coil 30 includes the first electromagnetic coil 30 having a space 32 extending in the direction of a predetermined axis Z; a cooling member 20 attached to an end surface 30e, with respect to the direction of the predetermined axis Z, of the first electromagnetic coil 30 and having a flow path for fluid internally formed; and an inlet pipe 22 and an outlet pipe 27 connected, within the space 52, to an inlet 21 and outlet 26, respectively, of the flow path of the cooling member 20 and extending through the space 32 to a region outside the electromagnetic coil 30.
