Schneider Electric ELAU SM‑100‑50‑030‑P0‑45‑M1‑B1 PacDrive AC Servo Motor

Product Description

The SM‑100‑50‑030‑P0‑45‑M1‑B1 is a high‑performance synchronous AC servo motor of Schneider ELAU PacDrive SM100 series. It adopts 100 mm flange size, equipped with multi‑turn absolute encoder and built‑in holding brake. The stator and rotor are optimized for high dynamic response, delivering stable continuous torque and peak overload capacity. The rugged IP65 housing and reinforced shaft structure adapt to heavy‑duty, frequent start‑stop industrial environments with dust, vibration and temperature fluctuation. It is specially matched with PacDrive motion controllers and widely available as spare replacement motor for packaging, machine‑tool and automated production lines.

Product Functions

• High‑precision speed, position and torque closed‑loop control for multi‑axis synchronized motion
• Built‑in multi‑turn absolute encoder, retaining position data after power‑off without homing operation
• Integrated electromagnetic holding brake to lock the shaft reliably when power is cut for safety protection
• High overload capability and fast acceleration/deceleration, suitable for cyclic short‑stroke dynamic movements
• Standard power and encoder connectors for quick wiring and plug‑and‑play connection with PacDrive servo drives
• Internal temperature sensor monitors winding temperature and provides overheat alarm signal to the drive unit
• Low cogging torque ensures smooth operation at low speed and improves positioning repeatability

Application Scenarios

• Packaging machinery, carton forming, filling, sealing and multi‑axis pick‑and‑place equipment
• Printing machinery, paper web tension control and rotary register correction systems
• Textile machines, plastic processing and automated assembly lines
• CNC machinery, gantry handling robots and material transfer automation skids
• Food & beverage processing machines requiring high‑accuracy synchronized motion control
• Spare replacement and retrofit of aging ELAU PacDrive SM100 servo motors on existing production machines

Common Problems

• Motor vibrates or runs noisily：bearing wear, shaft misalignment, mechanical load jamming or encoder signal interference
• Positioning deviation and repeatability decline：encoder contamination, cable shielding failure or loose coupling
• Holding brake cannot release or lock failure：brake coil burnout, insufficient brake control voltage or mechanical sticking
• Over‑temperature alarm during operation：overload duty cycle, poor heat dissipation, fan failure or winding insulation aging
• Drive reports encoder communication fault：damaged feedback cable, loose connector or internal encoder circuit degradation
• Motor cannot output full torque：power cable voltage drop, drive parameter mismatch or magnet demagnetization
• Water and dust ingress leading to intermittent failure：seal aging, damaged shaft lip seal and corrosion of internal components
