Abstract
The invention provides a steel wheel-type linear motor in which a protective coverhaving insulating properties and coming in direct contact with a stator coilis located on the ground side of the stator coilprotruding from a stator core; a vent hole 11is formed in the protective coverto be opposite to a gap formed between ends of the stator coilprotruding from the stator core; and a barprotrudes from the stator coreand thus the protective coveron the stator coreside is pressed onto the stator coilto be supported by the bar, the protective coveron the side opposite to the stator coreis fixed to the stator coilby a fastener memberhaving insulating properties that goes through the vent holes 11, and the stator coiland the protective coverare formed to be of integral structure using an insulating varnish.
