Title:
VARIABLE DAMPING CIRCUIT FOR A SYNCHRONOUS SERVOMOTOR
Document Type and Number:
WIPO Patent Application WO/2011/042186
Kind Code:
A3
Abstract:
The invention relates to a damping circuit for a synchronous servomotor including at least one winding, wherein the circuit comprises at least one main damping resistor, a means for coupling the main damping resistor in series to the winding, and at least one additional damping cell comprising at least one additional damping resistor connected in parallel to the main damping resistor via a static switch coupled to a module for controlling the switch on the basis of a winding voltage. The control module includes, in parallel with the main damping resistor, a shunt having an output connected to the control input of the switch and a divider bridge connected to the shunt so as to form a comparator for comparing the winding voltage with the conduction voltage of the shunt.
