⚠ Important: Cross-brand replacements require drive parameter reconfiguration and mechanical interface verification. Consult your system integrator before substitution.
Why Choose the Original Model
- Native Drive Integration: Plug-and-play compatibility with Lexium 32 (LXM32) servo drives — no parameter mapping required.
- Certified Performance: Factory-matched torque curves and encoder calibration ensure rated accuracy from day one.
- Warranty & Traceability: Genuine parts carry full Schneider Electric warranty and traceable batch documentation.
- Reduced Commissioning Risk: Eliminates encoder protocol translation, mechanical adapter plates, and tuning iterations.
- Long-Term Availability: Schneider Electric maintains spare parts availability for active product lines for 10+ years.
Typical Applications
- Packaging Machinery: High-speed pick-and-place, form-fill-seal, and cartoning lines requiring precise position control.
- CNC & Machine Tools: Axis drives for milling, turning, and grinding centers with tight velocity loop requirements.
- Textile & Printing Equipment: Tension control and registration systems demanding smooth low-speed torque.
- Semiconductor & Electronics Assembly: SMT placement machines and wafer handling with sub-millimeter repeatability.
- Robotics & Collaborative Arms: Joint actuators in SCARA and Cartesian robot configurations.
- Material Handling: Conveyor indexing, palletizing, and sortation systems with frequent start-stop cycles.

| Connector Kit | VW3M3101 (motor connector set) |
Selection Guide
Use the following decision framework to confirm the BMH1403P11A2A is the correct model for your application:
- Torque Requirement: Confirm continuous load torque ≤ 3.5 N·m and peak torque ≤ 10.5 N·m. If higher torque is needed, consider BMH1403P22A2A (7.0 N·m) or BMH1403P32A2A (10.5 N·m).
- Speed Profile: Verify operating speed range. BMH1403P11A2A is rated to 3000 RPM continuous / 6000 RPM peak. For lower-speed, higher-torque profiles, evaluate BMH1402 series.
- Brake Requirement: This model has no holding brake. For vertical axes or gravity-loaded loads, specify BMH1403P11A2AB (with brake).
- Shaft Interface: Smooth shaft (no keyway). For keyed shaft, specify BMH1403T11A2A.
- Encoder Resolution: 17-bit SinCos encoder standard. Confirm drive firmware supports this encoder type.
- Environmental Rating: IP65 body / IP54 shaft end. For wash-down or high-humidity environments, verify sealing is sufficient or consider additional shaft sealing.

Replacement & Compatibility FAQ
Q: Can I use BMH1403P11A2A with a non-Schneider servo drive?
A: Technically possible with drives supporting SinCos encoder input and compatible power ratings, but requires full parameter commissioning and is not recommended for production environments without validation.
Q: What is the difference between BMH1403P11A2A and BMH1403P11A2AB?
A: The suffix “B” denotes a holding brake. The BMH1403P11A2AB includes a 24 VDC holding brake for vertical or gravity-loaded axes. All other specifications are identical.
Q: Is BMH1403P11A2A still in production?
A: Yes, as of 2026 this model remains an active Schneider Electric product. Contact us for current availability and lead time.
Q: Can this motor replace an older BSH series motor?
A: The BMH series is the successor to the BSH series. Mechanical and electrical interfaces differ; a direct drop-in replacement is not guaranteed. Consult Schneider Electric’s migration guide or contact Konmask for application review.
Q: Do you provide test reports or incoming inspection records?
A: Yes. Inspection records and conformity certificates are available upon request for all orders.
