Abstract (en)
A positioning and synchronization system for elevator car doors (12,14) includes an encoder (60) coupled directly to an encoder pulley (34) for interpreting the position and direction of the elevator car doors. Coupling the encoder directly to the encoder pulley eliminates intermediate linkages that introduce inaccuracies and also eliminates the need for translating the linear position of the elevator car doors into the rotary position of the motor. <IMAGE>
