Abstract (en)

[origin: WO0005802A1] A process and device for mounting the rotor of an electric motor, comprising a stator (70) affixed inside a motor housing (60), and a rotor (50) affixed to a crankshaft (30) journalled to a supporting block (10), said assembly being achieved by a control unit (120) commanding the radial displacements of an upper end of the crankshaft (30) having a lower end journalled to a lower bearing (80) mounted to the motor housing (60), each radial displacement being limited by a respective contact condition of the rotor (50) to a respective and adjacent portion of the stator (70), which condition is identified and registered, in order to allow the calculation of the center of the circumference which contains the contact conditions and the posterior displacement of the upper end of the crankshaft (30), until its geometric center is aligned with the calculated geometric center of said circumference.
