Method for producing a primary part for an electric motor produces a casing coated with a sealing compound, a modular block embedded in the sealing compound and a winding body in first and second molding compounds.

摘要

A casing is coated with a sealing compound. A modular block is partially embedded in the sealing compound. The casing is sealed with a cover and coated with a layer of sealing compound. A winding body in a first molding compound is embedded in a second molding compound with a higher melting point than the first compound. A sealed casing (50) contains the modular block with a winding body (10) and windings (20) on it. Cooling air passes into the casing through an air inlet (52) and flows around the windings directed towards tooth gaps in the winding body. An Independent claim is also included for a primary part for an electric motor.
