Abstract:
An electro-magnetic brake which is switched between an operative braking position and an inoperative position by transient pulses of current. It is held passively in the operative and inoperative positions with little or no current. This prevents the generation of heat, which would affect the accuracy of measurements where the brake is used in dimensional measuring equipment. In one form, permanent and semi-permanent magnets are arranged in parallel, and the magnetic polarity of the arrangement is flipped by transient current pulses in a surrounding coil. A capacitor may provide a reservoir of current to activate the brake in the event of a power supply failure.

Claim (Index 1):
A braking system for braking a movable member, comprising:\n a braking element having an operative braking position in which it applies a braking force to the movable member, and an inoperative position in which the braking force is released; and an electro-magnetic device, the electro-magnetic force of which is arranged to act on the braking element to switch it between the operative and inoperative positions; wherein the electro-magnetic device comprises: one or more active elements which are energisable by a transient pulse of electrical current to switch the braking element from the operative braking position to the inoperative position and from the inoperative position to the operative braking position; and one or more passive elements which maintain the braking element in the operative braking position and in the inoperative position, after the transient pulse has been removed from the active element or elements.
