Abstract
An electric motor, e.g., a linear motor, includes a cooling system, which may permit the dissipation of heat from the primary part of the electric motor in a simple but effective manner. The iron core and the coils may be surrounded by a potting compound that stabilizes one of the coils and the electrical leads of the latter so that channels are formed in the gaps of the iron core. A coolant, e.g., air, flows from a first flow chamber through the channels into a second flow chamber. The direct contact with the iron core, potting compound, and optionally with the regions of the coils that are not filled with compound produces effective cooling action, without having to forego advantages of stability provided by an encapsulated primary part.
