An electromagnetic braking device includes a brake disk, a fixed disk, an armature, a biasing member for biasing the armature, and a stator for attracting the armature. In a stator magnetic circuit member, a first yoke, a permanent magnet, and a second yoke are arranged in this order from one end to the other end of a U shape. In a rotatable state or a rotation braking state, even when the coil energization is OFF, the rotatable state or the rotation braking state is maintained. When a current of a predetermined magnitude flows through the coil in a first direction in the rotatable state, the state shifts to the rotation braking state, and when a current of a predetermined magnitude flows through the coil in a second direction in the rotation braking state, the state shifts to the rotatable state.

A method of controlling a brake system that includes a motor and an actuator. The method includes moving the actuator towards a retracted position; activating a timer; monitoring a motor characteristic of the motor and monitoring the timer; and determining the actuator has reached the retracted position after the timer meets or exceeds a predetermined time threshold before the motor characteristic has reached or exceeded a predetermined motor characteristic threshold.

An electromagnetically operable brake arrangement for decelerating a rotationally mounted shaft, includes a magnet, a coil, a spring element, an armature disk, a brake pad support, a damping plate and a friction disk, the damping plate being situated between the armature disk and the magnet; the damping plate having projections; each of the projections extending further in a radial direction than in a circumferential direction; in particular, the projections each jutting out axially; in particular, at least a subset of the projections being evenly spaced apart from each other in the circumferential direction.

A yaw braking assembly of a wind turbine is presented. Accordingly, the yaw braking assembly includes a bedplate support frame having an annular flange defining a plurality of recesses formed into a lower-most annular surface of the annular flange and extending at least partially through an axial thickness of the annular flange.

An electromagnetic brake device includes an armature rotatably supported about a rotational axis; a yoke including a groove, an inner cylinder portion, and an outer cylinder portion; and a coil arranged in the groove and configured to generate a magnetic force when energized and thereby attract the armature to the yoke. A first opposing surface of the armature facing the yoke includes a sliding surface configured to slide on the outer cylinder portion of the yoke, and a recessed portion disposed inward of the sliding surface in a radial direction and recessed in a direction away from the yoke. An inner perimeter area of a second opposing surface of the outer cylinder portion of the yoke and a third opposing surface of the inner cylinder portion of the yoke face the recessed portion of the armature and do not contact the first opposing surface of the armature.
