Abstract (en)
[origin: EP1271739A1] The characteristic magnitude of the electric motor is the value of its supply current. The current variation ( DELTA I2) is measured between a minimum value (Im) and the value (Io) at the start of a stabilized phase. The force (F), applied by springs (8a,8b) due to stretching ( DELTA z) caused by current between (Im) and (Io), is measured by application of F = k x DELTA z., where DELTA z is determined from the angle of rotation of the motor. <??>Method of calculating the relation K between motor (2) supply current variation driving a kinematic chain designed to displace a part (7) with respect to a support and the variation of the force applied by the motor on the moving part. The kinematic chain includes spring (8,8b) tensioned cables (5) having a known stiffness (k).
