Abstract

An electromagnetic actuator (6) has a substantially linear force displacement characteristic. This is achieved by two coils (16, 17) which produce magnetic fields which interact with respective armature members (19, 20). The force displacement characteristic of the armatures (19, 20) individually is a square law. However, in the actuator (6) they are arranged to operate in a push-pull fashion resulting in a linearised force displacement characteristic for the armature (10) as a whole. Biasing magnets (32, 33) are associated with respective coils (16, 17) in order to optimise the linearisation of the armature force displacement characteristic.
