Abstract
A proportional brake is provided and includes first and second bodies, a spring element, a coil and a booster coil. The first body includes brake plates and the second body includes thrust plates. The second body is disposed such that the thrust plates are interleaved with the brake plates and is rotatable and movable with respect to the first body. The spring element urges the second body to move toward the first body such that the thrust plates are urged toward braking engagements with the brake plates. The coil is provided at a first side of the brake plates and, when energized, generates a first flux moment on the second body in opposition to the spring element. The booster coil is provided at a second side of the brake plates and, when energized, generates a second flux moment on the second body in support of the spring element.
