BSH1402P21A2A is a Schneider Electric high-inertia AC servo motor featuring single-turn SinCos Hiperface feedback. Fully compatible with Lexium drives, this unit works seamlessly with automated motion architectures to deliver precise position tracking and stable industrial network communication.

Features and Benefits

• High Torque Performance: Delivers a continuous stall torque of up to 19.5 Nm and peak stall torque reaching 47.5 Nm depending on the matched drive.
• Dynamic Speed Capabilities: Engineered to operate reliably at a maximum mechanical speed of 4000 rpm for highly dynamic factory automation.
• High-Resolution Feedback: Integrated with a SinCos Hiperface encoder providing 131,072 points per turn for ultra-precise velocity and position loops.
• Rugged Protection Rating: Built to IP65 standards with an option to upgrade to IP67 via a dedicated kit, ensuring resilient operation in dusty or damp conditions.
• Sustainable Industrial Design: Classified as a Green Premium product conforming to REACh, RoHS, and eco-friendly circularity profiles.

System Compatibility & Alternatives

• System Compatibility:
  Fully compatible with Schneider Electric Lexium 05 and Lexium 15 drive families, specifically matching drive modules LXM05AD42M3X, LXM05AD57N4, LXM15LD28M3, LXM15MD28N4, LXM15MD40N4, and LXM15MD56N4 across three-phase power networks.
• Alternative Model & Differences:
  An alternative configuration from the same family is the brake-equipped variant BSH1402P21F2A.
• The Difference: The baseline BSH1402P21A2A is designed "without brake" for applications with lower static loading or vertical drift risks, resulting in a slightly lighter construction and distinct power wiring profiles. The "F" designated variant incorporates an internal electromagnetic holding brake that mechanically locks the untapped 24mm shaft end when the drive power is cut, protecting the machine axis from gravity-driven dropping or load slippage.

Installation & Troubleshooting FAQ

Q1: What are the specific alignment precautions for installing this untapped shaft motor?

A: Since the BSH1402P21A2A features an untapped shaft end without a keyway or threaded hole, it relies entirely on a high-friction compression coupling or a shrink-disc adapter. Ensure both the 24mm motor shaft and the load-side coupling bore are fully degreased before fastening. Misalignment can exceed the maximum radial force ratings (up to 2430 N at lower speeds) and cause premature bearing failure.

Q2: How do I upgrade the motor housing from IP65 to IP67 protection for washdown environments?

A: The standard motor ships with an IP65 ingress rating. To upgrade to IP67, you must purchase and install an official IP67 seal kit, which includes a heavy-duty shaft oil seal. This seal requires routine lubrication and prevents pressurized water or cutting fluid from penetrating along the smooth shaft end into the front bearing race.

Q3: Why is the drive reporting a position tracking error or feedback communication loss?

A: This is usually caused by electromagnetic interference (EMI) or moisture entry inside the straight electrical connectors of the SinCos encoder cable. Inspect the plug connections for oil mist contamination or loose locking rings. Ensure that the feedback cable utilizes high-quality shielding and is routed completely away from high-voltage, high-current drive power cables.

Q4: Can the BSH1402P21A2A motor be safely driven by a standard variable frequency drive (VFD)?

A: No, it cannot. The motor incorporates a 10-pole permanent magnet rotor and a high-resolution encoder requiring synchronous vector control logic. Running this unit on a standard VFD without synchronous rotor position tracking will cause an immediate overcurrent trip, severe motor stall, or permanent demagnetization of the internal magnets due to mismatched field angles.
