Thanks in advance M.G

(0)  Hello Mahmoud Gad, Technically there is no difference between the Core Type Servo Motors and the Standard Type servo motors. The distinction is that the Core Type servo motors have a very limited number of configurable options for part number so a cost savings is offered to customer to attempt to streamline production in factory, parts availability, etc.   This can be viewed by observing the Siemens PM 21 2011 catalog.  Factory lead time is same currently although it is possible that in future there could be a shorter lead time for Core Type servo motors as well when compared to the Standard Type servo motors. For instance, if comparing two part numbers with only difference in part number being the digit which specifies Core Type with a "1" in eighth digit (versus a "5") then same technical description, speed/torque curves, etc. would apply. See example below. 1FT7044-1AF71-1NG1 SYNCHRONOUS MOTOR 1FT7, 5 NM (100K), 3000 RPM,1,35KW NATURAL AIR COOLING; POWER CONNECTOR ROTATABLE VIBRATION SEVERITY GRADE A PROTECTION CLASS IP 65; FRAME SIZE IMB 5 (IM V1, IM V3) FLANGE 1 (1FT6 COMPATIBLE) INCREM. ENCODER SIN/COS 1VSS 2048 S/R (ENCODER I-2048) CONNECTOR ROTATABLE PLAIN SHAFT, W/O HOLDING BRAKE; ACCURACY TOLERANCE N 1FT7044-5AF71-1NG1 SYNCHRONOUS MOTOR 1FT7, 5 NM  (100K), 3000 RPM, 1,35KW NATURAL AIR COOLING; FRAME SIZE IMB 5 (IM V1, IM V3) FLANGE 1 (1FT6 COMPATIBLE) POWER CONNECTOR ROTATABLE INCREM. ENCODER SIN/COS 1VSS 2048 S/R (ENCODER I-2048) CONNECTOR ROTATABLE PLAIN SHAFT, W/O HOLDING BRAKE; ACC. TOLERANCE N VIBRATION SEVERITY GRADE A, DEGREE OF PROTECTION IP 65 Deputy
