Whether you are managing a scheduled annual overhaul, responding to an emergency motor failure, or building a strategic spare parts buffer for a multi-axis Lexium drive system, the BMH1002P22A2A can be sourced, verified, and shipped with full traceability documentation to support your maintenance records.

Spare Maintenance Table

Maintenance Planning for Continuous Operation

Replacing the BMH1002P22A2A in a live production environment requires more than a motor swap. Experienced maintenance engineers know that a servo motor failure is rarely an isolated event — it is often symptomatic of broader stress across the motion control loop. Before or during replacement, the following components should be inspected and, where appropriate, held as co-stocked spares:

Servo Drive (LXM32 / Lexium 32 series): The BMH1002P22A2A is typically paired with a Lexium 32 servo drive. A motor failure caused by overcurrent or bus voltage spikes may have stressed the drive’s IGBT output stage. Verify drive fault history and check DC bus capacitors before recommissioning.

Motor Power Cable and Brake Cable: The BMH series uses dedicated shielded motor power cables. Inspect for insulation breakdown, connector pin corrosion, and shield continuity. A degraded cable can cause recurring encoder errors even after motor replacement.

Encoder Feedback Cable: The incremental or absolute encoder cable connecting the BMH1002P22A2A to the drive is a high-frequency signal line. Any damage, improper routing near power conductors, or connector oxidation will produce position feedback errors and drive faults.

24 VDC Control Power Supply (e.g., Phaseo ABL series): Servo drives and their logic boards depend on stable 24 VDC auxiliary power. A failing Phaseo power supply can cause intermittent drive resets that are misdiagnosed as motor faults. Include a spare 24 VDC PSU in your control cabinet inventory.

Safety Relay / STO Module: The Safe Torque Off (STO) circuit connected to the Lexium drive must be verified after any motor replacement. A faulty safety relay or wiring fault in the STO loop will prevent the drive from enabling, causing unnecessary commissioning delays.

I/O Module (TM3 / TM2 series): If the BMH axis is coordinated via a Modicon M241 or M251 PLC with TM3 expansion I/O, inspect the digital output modules driving the drive enable and fault reset signals. Worn relay contacts or failed transistor outputs can cause intermittent axis enable failures.

Terminal Blocks and Grounding Bars: Loose or corroded terminal connections in the servo power circuit are a common root cause of motor overheating and encoder noise. During motor replacement, re-torque all terminal connections and verify PE grounding continuity from motor frame to cabinet earth bar.

Fuses and Circuit Breakers (GV2 / GV3 series): Verify that the motor branch circuit protection — typically a GV2 or GV3 motor circuit breaker — has not been thermally stressed by the fault event. A weakened breaker may nuisance-trip under normal motor inrush, or fail to trip under a genuine fault.

Communication Module (CANopen / EtherCAT): If the Lexium drive is networked via CANopen or EtherCAT fieldbus, confirm that the communication module and network termination resistors are intact. A loose fieldbus connector can cause axis synchronisation errors that appear as motor faults in the PLC diagnostic log.

HMI / Operator Panel (Magelis / Harmony series): After motor replacement and drive recommissioning, verify that the HMI alarm history is cleared and that any axis position presets or homing sequences are re-executed correctly. An outdated HMI program may reference deprecated drive parameters from a previous firmware version.

Site Replacement Workflow

The BMH1002P22A2A is a direct replacement for worn or failed units within the Lexium BMH motor family. Follow this structured workflow to minimise replacement time and ensure system compatibility:

Step 1 — Pre-Replacement Verification: Confirm the replacement unit’s nameplate data matches the installed motor: frame size, rated torque, encoder type (incremental vs. absolute), shaft configuration, and brake option. Cross-reference the drive’s motor configuration parameters (motor type, encoder resolution, pole pairs) stored in the LXM32 drive or in your PLC project backup.

Step 2 — Drive Parameter Backup: Before disconnecting the failed motor, use SoMachine or EcoStruxure Machine Expert to export the full drive parameter set. This ensures that tuning gains, speed limits, and safety parameters are restored identically after the swap.

Step 3 — Safe Isolation: De-energise the servo drive via the main circuit breaker and discharge the DC bus (minimum 5-minute wait or verify with a DC voltmeter). Engage the mechanical brake if fitted. Follow your site LOTO (Lockout/Tagout) procedure before disconnecting motor cables.

Step 4 — Motor Swap and Cable Reconnection: Mount the replacement BMH1002P22A2A to the machine frame, reconnect the motor power cable, encoder cable, and brake cable in sequence. Verify connector locking and cable routing away from heat sources and moving parts.

Step 5 — Drive Recommissioning: Restore the saved parameter set to the drive. If the replacement motor uses an absolute encoder, perform the encoder initialisation (zero-point setting) procedure as specified in the Lexium 32 commissioning guide. Run a no-load jog test before reconnecting the mechanical load.

Step 6 — Functional Test and Documentation: Execute a full motion profile test at reduced speed, then at rated speed. Log the replacement in your CMMS with the new motor serial number, installation date, and drive parameter file version. Update your spare parts inventory to trigger reorder of the consumed BMH1002P22A2A unit.

Spare Parts Support FAQ

Q1: Is the BMH1002P22A2A still available as a new original spare part?
A: Yes. NINERMAS maintains sourcing channels for Schneider Electric Lexium BMH series motors, including end-of-life and long-lead SKUs. The BMH1002P22A2A is available as an original spare. Contact our team for current stock status and lead time confirmation before raising a purchase order.

Q2: How is the BMH1002P22A2A tested before shipment?
A: Each unit undergoes pre-shipment inspection covering nameplate verification, encoder signal integrity check, winding resistance measurement, and insulation resistance test. A test report is available upon request. Units are packed in anti-static, shock-protected packaging with full traceability documentation.

Q3: What is the warranty coverage and what does it include?
A: All BMH1002P22A2A units supplied by NINERMAS carry a 12-month warranty from the date of shipment. The warranty covers manufacturing defects and verified premature failure under normal operating conditions. It does not cover damage caused by incorrect installation, overvoltage events, or mechanical overload. Our technical team provides post-sale support for installation and commissioning queries.

Q4: Can NINERMAS support long-term supply agreements for the BMH series?
