Abstract
A primary part of an ironless linear motor includes a cooling plate on which flat coils are disposed, each having a central opening. The coils are pressed onto the cooling plate by holding pieces which taper toward the cooling plate and engage in the openings in the coils. In this manner, an especially good contact is produced between the flat coils of the primary part and the cooling plate prior to encapsulating the primary part with a synthetic resin, the cooling effect of the preferably actively cooled cooling plate thereby being increased markedly.
