Document Type and Number:
WIPO Patent Application WO/2022/155887
Kind Code:
A1
Abstract:
A brake apparatus for a motor and a robot, comprises: a first ring (10) connected to a shaft (12) and being rotatable together with the shaft (12), the first ring (10) comprising a first set of magnets (101, 103, 10-1, 10-2, …, 10-N); a second ring (20) spaced apart from the first ring (10) by a gap and comprising a second set of magnets (201, 203, 20-1, 20-2, …, 20-N), the second set of magnets being magnetically coupled to the first set of magnets such that the second ring tends to rotate along with the first ring; a first member (22) connected to the second ring (20); and a second member (30) being switchable between a first state and a second state, wherein the second member (30) is engaged with the first member (22) to block a rotation of the first member in the first state, and the second member (30) is disengaged from the first member (22) to allow the rotation of the first member in the second state. A damping effect can be achieved during braking.
