20140210311 | Noiseless Electromechanical Motor - An electromechanical motor ( | 07-31-2014 |
20130062997 | Rotating Load Bearer - An electromechanical rotating actuator arrangement ( | 03-14-2013 |
20120212103 | PROVISION OF A NORMAL FORCE TO ELECTROMECHANICAL MOTOR - An electromechanical motor assembly includes a stator, a body to be moved and a stator support. The stator has a plurality of electromechanical actuators for moving the body by repetition of steps ensuring that at least one of the electromechanical actuators is in non-sliding contact with the body at every time. The assembly further includes a force applying arrangement for supplying a normal force (N) between the stator and the stator support by at least one spring arrangement. The spring arrangement has a spring constant in the direction (Z) normal to the surface of the body that is lower than 5% of the ratio between the normal force and the average height uncertainty of the surface of the body. The force applying arrangement includes a lateral fixing plate attached between the stator and the support parallel to the main motion direction (X) and juxtaposed to the surface of the body. | 08-23-2012 |
20120098468 | ELECTROMECHANICAL MOTOR - An electromechanical motor includes an actuator assembly and a body to be driven in a driving direction. The actuator assembly has an actuator backing, a first actuator and a second actuator. The actuators are mechanically attached by a respective single attachment to the actuator backing at a first end of the actuators. The actuators have a respective interaction portion constituting a second end opposite to the first end in an actuator direction transverse to the driving direction. The interaction portions are arranged for interaction with an interaction surface of the body by a respective contact area. The actuators include a respective unimorph member arranged for causing a movement of the respective contact area as a response of a respective electrical signal. The respective movements are transverse to the actuator direction, to the driving direction, and to each other. | 04-26-2012 |
20100148629 | GUIDED ELECTROMECHANICAL MOTOR - An electromechanical actuator arrangement ( | 06-17-2010 |
20100019622 | ELECTROMECHANICAL ACTUATORS AND MANUFACTURING METHOD THEREOF - An electromechanical actuator comprises a bimorph element ( | 01-28-2010 |
20090243434 | SHOCK RECOGNITION SYSTEM IN A DOORLOCK - An electromechanical motor, comprising a stator, including a drive unit and a frame portion, the frame portion holding the drive unit. The motor includes a shuttle adapted to be moved relative to the stator in a displacement direction, the shuttle movement being controlled by the drive unit and where the drive unit comprises at least one electromechanical drive element, extending along said displacement direction, and a drive body adapted to transfer a movement of the drive element onto the shuttle. The motor includes a sensor connected to the drive element and adapted to sense an electric or magnetic signal generated by the drive element in response to mechanical stress being applied to the drive element and to output a sensor signal. | 10-01-2009 |
