Abstract
An electromagnetic braking system includes a brake stack (), a ram () shiftable in a first linear direction toward and against the brake stack () and in a second linear direction opposite the first linear direction, a motor () having an output shaft () mechanically connected to the ram () and rotatable in a first rotation direction for moving the ram () in the first linear direction and in a second rotation direction for moving the ram () in the second linear direction, at least one friction member () having a friction surface () mounted adjacent to the motor output shaft (), and an friction surface () for moving the friction surface () of the at least one friction member () against the motor output shaft () in a non-locking manner and holding the friction member () against the motor output shaft () with a predetermined force to perform a park brake function, wherein the predetermined force is low enough to allow the output shaft () to slip when a rotational force on the output shaft () exceeds a given level. Also a method for performing a park brake function.
