MAGNETIC CLUTCH FOR A DC MOTOR

摘要

A device for a brake system comprises a rotating plate including magnets having a first polarity. The rotating plate engages an output shaft of a motor. The device includes a non-rotating plate including magnets, one or more of which have the first polarity and one or more of which have a second polarity. The non-rotating plate moves axially between an engaged position and a non-engaged position. In the engaged position, the magnets in the rotating plate magnetically attract the one or more magnets in the non-rotating plate with the second polarity so that non-rotating plate moves into contact with the rotating plate. In the non-engaged position, the magnets in the rotating plate magnetically repel the one or more magnets in the non-rotating plate with the first polarity so that the non-rotating plate moves out of contact with the rotating plate and thus rotation of the rotating plate is allowed.

1. A device for a brake system comprising:
a rotating plate including rotating magnets having a first polarity, the rotating plate is configured to engage an output shaft of a motor; a non-rotating plate including non-rotating magnets, one or more of the non-rotating magnets have the first polarity and one or more of the non-rotating magnets have an opposing second polarity, the non-rotating plate moves axially along an axis between an engaged position and a non-engaged position; wherein in the engaged position, the rotating magnets are generally aligned with and magnetically attract the one or more non-rotating magnets having the second polarity so that non-rotating plate moves axially along the axis and into contact with the rotating plate so that rotation of the rotating plate is inhibited, and wherein in the non-engaged position, the rotating magnets are generally aligned with and magnetically repel the one or more non-rotating magnets having the first polarity so that the non-rotating plate moves axially along the axis out of contact with the rotating plate so that rotation of the rotating plate is no longer inhibited.
