Abstract

The invention relates to a primary part of a linear motor having a receptacle for a secondary part which can move along an axis in the receptacle, having a plurality of annular coils which are arranged coaxially with respect to the receptacle, and having a yoke, with teeth which are composed of a soft-magnetic material being arranged or formed between the end faces of adjacent coils. In order to provide a primary part or a linear motor which has a high power density in a compact form and allows good cooling with coolant, cooling gaps in which spacers are arranged are formed between the end faces of the coils and the teeth.
