A method may include receiving, via a processor, a request to enable movement of a rotor. The method may involve sending a first signal to a mechanical relay system in response to receiving the request, such that the second signal may cause a mechanical relay to close. The mechanical relay system is configured to couple a first conductor to an EM brake. The method may also include sending a second signal to a solid-state relay system after sending the first signal to the mechanical relay system, such that the second signal may cause a solid-state relay to close. The solid-state relay system may couple a second conductor to the EM brake, such that the EM brake may open after receiving power via the first conductor and the second conductor.

Described herein is a device comprising members in a kinematic relationship. The kinematic relationship is at least partially governed by at least one magnetic flux interaction that, in effect, may provide a tunable resistance to movement, changing the rate of relative movement between the members. In one embodiment, the device comprises a first member in a kinematic relationship with at least one further member to form a system. The system moves within a limited range of motion and the system interacts when an external energizing force is imposed on the system causing the members to respond due to their kinematic and dynamic characteristics and thereby creating relative motion between the members. The trigger member is coupled to the at least the first member and moves in response to a pre-determined system movement. When the trigger member moves, the trigger member imposes a braking action on the system or a member or members thereof. The speed and/or intensity of the braking action imposed by the trigger member on the system or a member or members thereof is controlled by the trigger member rate of movement. This rate of movement is in turn governed by a magnetic flux interaction between the trigger member and the at least one first member causing formation of a magnetically induced eddy current force between the parts.

The present application provides a brake apparatus for a rotating component, a robot joint and a robot including the same. The brake apparatus includes: a locking component including a locking end provided with a first magnet; and a brake component including a mounting portion connected to the rotating component and a plurality of brake ends provided on the mounting portion along a circumferential direction of the mounting portion. Each of the plurality of brake ends is provided with a second magnet. A side of the first magnet facing the brake component is configured to have same polarity as sides of the second magnets facing the locking component. A distance from the first magnet to a rotary axis of the rotating component is substantially the same as distances from the second magnets to the rotary axis of the rotating component.

A method includes a first brake block of a first brake rubber, a second brake block mounted with a second brake rubber and a mounting base for mounting the first and second brake blocks. The second brake rubber is movable along a direction slanted with respect to an axis of rotation of the traction sheave. A brake block actuation member is triggered by the brake blocks to enable the first and the second brake rubbers to hold the traction sheave. A switching member is also triggered by the action of the second brake rubber, cutting off a safety circuit of the elevator. The external power is cut off, and the brake block actuation member enables contact between the second brake rubber and the traction sheave. The traction sheave further drives the second brake rubber triggering the brake block members to generate frictional braking force to stop the traction sheave.

An electromagnetic brake assembly includes a solenoid coil; a fixed ferrous brake stator; a ferrous armature having a braking face, wherein the armature is moveable in a translation direction relative to the brake stator between a disengaged position and an engaged position; and a rotating member including a mating surface and that rotates relative to the armature when the armature is in the disengaged position. When the solenoid coil is energized, the armature translationally moves from the disengaged position to the engaged position, and in the engaged position the braking face of the armature interacts with the mating surface of the rotating member to apply a braking force to the rotating member. The braking face and the mating surface may form a conical interface, and the conical interface further may include a friction O-ring positioned within a slot that permits the O-ring to roll along the braking interface when the armature moves between the disengaged position and the engaged position.
