(0)  Dear dears, My application requires: 1. High efficiency relative to waight. 2. High speed 2500 RPM to 3000RPM. 3. Drive controlled (position control) 4. Built in mechanical cluch for engaging/disengaging rotor ( b/c my application requires very low ramp up time). 5. 3Kw or nearest available. Based on the above could you suggest me some models?

(0)  Hello, please follow the link to find some possible motors: https://intranet.automation.siemens.com/mcms/mc/en/motors/motion-control-motors/simotics-s-servomotors/Pages/synchronous-motor.aspx Relating high dynamic by less motor inertia the 1FT7 is a very good choice. E.g. 1FT7066-xAF with 2,92KW @ 3000upm Controlled could be the motors via SINAMICS S120. The point 4 will be a problem. Because the smaller Siemens motors (1FK/1FT) have no integrated clutch. Maybe you can connect an external clutch. Best regards TechTeam

(0)  Hello, I agree that the point # 4 is not available from Siemens motors in this size range for 1FT/1FK servo motors. Attached is a sample bill of material for motor and drive system. Note:  The motor in bill of material does not have a holding brake.  If a holding brake is needed then bill of material would need to be modified slightly. You can look at drawing for motor by viewing on website at CAD CREATOR tool. http://staging04.it-motive.de/CADCreator/VorNavigation.cfm?IdListVornavi=(0-1*906)&CFID=4412387&CFTOKEN=22532204&Scenario= Best Regards, Deputy Attachment: 1FT7066 Example.pdf  (10 Downloads)

(0)  Thanks for your replay! I don't mean mechanical brake, I mean mechanical clutch for engaging and disengaging the rotating rotor. The advantage of this is the rotor is continously runing but if we want to rotate the shaft we have to activate the clutch, in this way the speed of shaft reaches its maximum speed in a very short time (much much better than any of motor drives). My point is is there any Siemens motor having mechanical clutch? Thanks again You like it? Rate it ! ለማንኛውም የፋብሪካ አውቶሜሽ ስራ፣ በተለይም፡ ፒ. ኤል.ሲ፣ድራይቭ፣ኮምፒዩተራይዝድ ማሽን ስራ፡በዚህ ይደውሉ 0922 493737
