Method and system for electronic braking of an electric motor having no permanent magnets

摘要

System for braking either linear or rotary electric motor having no permanent magnets comprising at least one servo amplifier and an electronic circuit for generating a pulsed control signal for controlling the braking of the motor. The electronic circuit of the present invention may be responsive to any emergency such as loss of the line power, a motion controller failure, or actuation of a limit switch by a driven member. A method of braking is also disclosed.
