Code Breakdown:
-
E2C = EC2 actuator family
-
AKM23D = Motor type (NEMA23-class BLDC, D winding)
-
B2C = Mounting/feedback configuration
-
15 = 1:1 inline or belt ratio group
-
05B = 5 mm ball-screw lead
-
250 = 250 mm stroke
-
MF = Male threaded rod end + flange options
-
-

-
-
Functional Features: Clean linear motion without hydraulics, PLC-controlled positioning, autotune with AKD/S700, multiple rod-end choices.
-
Application Scenarios: Valve actuation, dosing, medical table lift, packaging pushers, fixture clamping.
-
Installation Requirements: Front/rear rectangular flange or trunnion; align load to avoid side moment > catalog limit; use flexible coupling if misalignment risk.

Cross-Series Note
All above devices are legacy or current Kollmorgen/Danaher Motion products. For new designs Kollmorgen directs users to AKD2G + AKM2G, AKD, or S700 platforms; 6SM motors cross to AKM/AKM2G, EC2 actuators remain commercialized as electric cylinder line.
