Through experimental analysis, the design uses DSP and Intelligent Power Module (IPM) bination of control system for elevator door operation by setting curve and stable operation.Keywords： Permanent magnet linear synchronous motor。Elevator Door Machine。 DSPI. INTRODUCTIONThe traditional elevator door, warehouse door and civil came dooropening always drove by motor, because crane is a straightline motion electromechanical integration device of frequent reciprocating,not only its operation and good safety requirements, but the smooth operation and low the door is straightline motion with reciprocating movement,the designation of a mechanical device,which transition the rotary motion of the motor to straightline motion needed to realize the door open/close,is necessary.[1] At present elevator door market in domestic,drive motor mostly adopt AC asynchronous motor or linear motor, due to the high speed,position and difficult control of the AC asynchronous motor,it must have slow institutions contains belt or gear transmission etc,which make its structure plex,efficiency lowly,noisy and the performance of speed poorly. Though the performance of speed of linear motor is easy,but for the existence of mentator,the reliability is poor,and easy to produce electromagnetic interference and spark,also need DC electrical source,difficulty to using a PMLSM as drive motor,can save the transmission mechanism between motor and the gate,direct driving gear for linear motion,improve the reliability and safety of the paper introduce the elevator door is using a PMSLM as drive mechanical structure drawing shown in figure 1, D1 and D2 are connected by a belt,through the PMLSM motor to realize two doors synchronous open/’s control circuit adopts the TMS320LF240X TI Company LF2407 series as control chip,bining with intelligent power module IPM,to realize the door stable operate according to the curve set.Figure 1 Mechanical structure diagram of elevator doorII.
