Abstract
Apparatus for braking either a linear or rotary electric motor having no permanent magnets comprising at least one position sensor for outputting an electrical characteristic representative of motor position 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 line power, a motion controller failure, or actuation of a limit switch by a driven member.
