Patent ID: 8912708

Claim:
An electromechanical motor, comprising: an actuator assembly; a body, relative to which said actuator assembly is to be acting for causing a relative displacement of said body in a driving direction; said actuator assembly having an actuator backing, a first actuator and a second actuator; said first actuator is mechanically attached by a single attachment; said single attachment of said first actuator is a first attachment to said actuator backing, said first attachment being provided at a first end of said first actuator; said first actuator having a first interaction portion constituting a second end of said first actuator, said second end of said first actuator being opposite to said first end of said first actuator in an actuator direction; said second actuator is mechanically attached by a single attachment; said single attachment of said second actuator is a second attachment to said actuator backing, said second attachment being provided at a first end of said second actuator; said second actuator having a second interaction portion constituting a second end of said second actuator, said second end of said second actuator being opposite to said first end of said second actuator in said actuator direction; said actuator direction being transverse to said driving direction; said first interaction portion and said second interaction portion being arranged for interaction with an interaction surface of said body by a respective contact area; said first actuator and said second actuator comprise a respective member comprising an electromechanical material arranged between a respective said first end and a respective said second end of said first actuator and said second actuator; each of said members that comprises an electromechanical material being arranged for causing a one-dimensional movement forth and back of a respective said contact area as a response of a respective single electrical signal; and said respective one-dimensional movements are transverse to said actuator direction, transverse to said driving direction, as well as transverse to each other; each of said members that comprises an electromechanical material comprises an active volume, exhibiting a change in dimension as a response of said single electrical signal applied thereto, and a passive volume mechanically attached to a respective said active volume along said actuator direction; said active volume of said first actuator is positioned before said passive volume in said driving direction; and said active volume of said second actuator is positioned after said passive volume in said driving direction.
