Abstract
The invention relates to a motor part of a linear motor, i.e. the primary part or secondary part of an asynchronous or synchronous linear motor. According to the invention, it is proposed to configure a cooling coil (K), which has a meandering flat structure, from pipe sections (10) of a material with high heat conductivity, as well as plastic deflections (12, 13). The deflections are preferably configured as pre-fabricated molded plastic parts, and the motor element is preferably cast with the attached cooling coil. According to the invention, cooling coils can be configured from modules in accordance with the required dimensions, and problems caused by bending the metal parts are avoided.
