Abstract

A magnet assembly in an electric drive having a shaft. The assembly includes a permanent magnet bonded in plastic and having two protrusions. An adapter has two protrusions and two recesses. The end face of the shaft has two cavities, which receive the two adapter protrusions to mount the adapter to the shaft. The two protrusions of the magnet are received in the recesses in the adapter in order to mount the magnet to the adapter. In another embodiment the shaft has an outer circumferential surface. Here, the adapter has a recess of a first shape and a second recess for mounting the adapter onto the outer circumferential surface of the shaft and the permanent magnet has a protrusion shaped to mate with the first shape of the first recess in the adapter, and the first recess is configured to receive the protrusion to mount the magnet to the adapter.
