DEVICE WITH MAGNETIC COUPLER AND ELECTRIC TOOL ASSEMBLY HAVING SUCH A DEVICE

摘要

The present invention is concerned with a device for converting a rotating input motion into a modified output motion. The device has a magnetic coupler including a secondary magnet, a motion output member, and one, or at least a first, primary magnet. The magnetic or polarity profile of the first primary magnet and the magnetic or polarity profile of the secondary magnet are different. The device is configured such that rotating movement of the first primary magnet translates to a combination of rotating and oscillating movement of the motion output member.

主权项

1. A device for converting a rotating input motion into a modified output motion comprising:
an electric motor with a rotatable shaft defining a rotation axis; at least one primary magnet connected to the rotatable shaft and configured to spin with the rotatable shaft in use at the rotation axis; a secondary magnet arranged between the at least one primary magnet and a modified motion output means for generating, in response to movement or change in magnetic field of the at least one primary magnet, a modified output motion to the modified motion output means; wherein the at least one primary magnet includes two ends defining north pole and south pole thereof, and the secondary magnet includes two ends defining north pole and south pole thereof, and the primary and secondary magnets have different magnetic profiles, whereby rotational movement of the at least one primary magnet causes change in magnetic field, resulting in the modified output motion of the modified motion output means; wherein the modified output motion is a combination of rotating motion and oscillating motion; and wherein the magnetic profile of the at least one primary magnet resembles two halves defining the north pole and the south pole of the at least one primary magnet.
