Triac drive mechanism for elevator door actuator with linear motor-driven trafasica line.

A MECHANISM ELECTRONIC DRIVE MOTOR PRODUCE A PROFILE OF MOVEMENT REQUIRED FOR ACTUATOR ELEVATOR DOOR POWERED BY AN INDUCTION MOTOR LINEAR (LIM) POWERED BY LINE TRIFASICA THROUGH A NETWORK OF SWITCHES TRIAC PRODUCING FORCES SELECTED FROM THE LIM. The drive mechanism is capable of producing TRIAC ACCELERATION, DECELERATION, OR RUN FREE COASTS IN THE DIRECTION OF OPERATION OPENING OR CLOSING THE DOOR. When controlled by an algorithm AS A CONTROL "switch point TIME OPTIMAL" or "all or nothing", the drive mechanism TRIAC PRODUCE THE MOVEMENTS REQUIRED FROM MOTOR INDUCTION LINEAR OPERATING DOOR ELEVATOR. Motor windings are switchable between TRIANGLE AND STAR CONNECTIONS FOR TWO DIFFERENT LEVELS OF THRUST. It IS USED MODULACION phase angle CONTROL FOR PUSHING Finer. The linear motor may be a device 12-slot FOUR POLES AND THREE PHASES AND BE SO WILLING TO EMANE FLOW primary stationary (in the cabin) to a part of back iron STATIONARY high school, also mounted in the cockpit, where the flow PASSING THROUGH A PART OF SECONDARY COPPER MOBILE ATTACHED TO THE DOOR OF ELEVATOR AND passing between the primary and the back iron.
