Precision Motion Control Solution – SEW-EURODRIVE CMP40M/BK/KY/RH1M/SB1 | CMP Series
Where This Product Is Used
The SEW-EURODRIVE CMP40M/BK/KY/RH1M/SB1 synchronous servomotor is engineered for demanding motion-control applications where compact footprint, high torque density, and precise positioning are non-negotiable. Typical deployment environments include:
- Packaging machinery – high-cycle pick-and-place arms, form-fill-seal axes, and labeling heads
- Conveyor & material handling – indexing stations, accumulation conveyors, and sortation diverters
- CNC & machine tool auxiliaries – tool-changer actuators, rotary tables, and clamping axes
- Robotics & gantry systems – joint drives in Cartesian and SCARA configurations
- Textile & printing equipment – tension-controlled winding/unwinding and registration axes
- Food & beverage processing – hygienic-area dosing pumps and portioning conveyors (IP-rated enclosure)

Why Engineers Specify This Model
- Integrated holding brake (BK) – eliminates external brake modules; load is held safely on E-stop or power loss without additional hardware cost
- Keyway shaft (KY) – positive torque transmission to pulleys, couplings, and pinions; no slip under shock loads
- High-resolution resolver (RH1M) – robust, EMI-immune feedback ideal for harsh industrial environments; no battery backup required
- Compact CMP40 frame – fits space-constrained machine designs while delivering high peak torque-to-inertia ratio
- Native MOVIDRIVE® / MOVITRAC® compatibility – plug-and-play commissioning with SEW drive systems; auto-parameterization via DriveRadar®
- Angled connector (SB1) – reduces cable-bend radius in tight enclosures; simplifies cable routing and maintenance access

Application-Specific FAQ
Q: Is this motor compatible with SEW MOVIDRIVE® B series inverters?
A: Yes. The CMP40M with RH1M resolver is natively supported by MOVIDRIVE® MDX60B/61B. Use SEW’s DriveRadar® or MOVITOOLS® MotionStudio for auto-parameterization.
Q: What is the brake release voltage?
A: The BK holding brake is spring-applied and electrically released. Standard release voltage is 24 V DC via SEW’s BG brake rectifier module. Confirm exact specs on the motor nameplate or SEW documentation for order number 0200-36642.
Q: Can the shaft keyway be used with a standard DIN 6885 key?
A: Yes. The KY designation indicates a DIN 6885 Form A keyway. Match key dimensions to the shaft diameter specified in SEW’s dimensional drawing for CMP40.
Q: What feedback resolution does the RH1M resolver provide?
A: The RH1M is a single-turn resolver. Effective resolution depends on the R/D converter in the drive; MOVIDRIVE® B achieves up to 4096 increments/revolution from this resolver.
Q: Is export to non-EU countries supported?
A: Yes. Konmask.com ships globally. HS code 8501.52 applies. Buyers are responsible for local import duties and compliance. We provide commercial invoice and packing list for customs clearance.
