Eddy current brake for testing engines has drive shaft for connecting engines to be tested, relief grooves or bores provided in each end surface of cooling chambers facing rotor

摘要

The device has a drive shaft for connecting engines to be tested, at least one stator winding arranged in a magnetisable part as a stimulator and at least one rotor (3) consisting of a magnetisable material that transfers the power primarily into the cooling chambers (6,7). Relief grooves (12) or bores are provided in each end surface (15) of the cooling chambers facing the rotor.
