Usage Methods
- Installation:
-
- Mount the motor to the machine frame using M5 bolts (torque: 8 Nm), ensuring the flange is properly aligned to prevent shaft misalignment.
-
- Use a flexible coupling to connect the motor shaft to the load, limiting misalignment to ≤0.1mm axial and ≤0.05mm radial for optimal bearing life.
-
- Ensure the mounting surface is flat (≤0.1mm/100mm) to avoid distortion of the motor housing during installation.
-
- Position the motor away from direct heat sources (e.g., heaters, furnaces) to maintain ambient temperature within -20°C to +40°C.
- Wiring and Connection:
-
- Connect the motor windings (U, V, W) to the servo drive using twisted-pair, shielded cable (min. 0.75mm² cross-section), ensuring correct phase sequence to avoid reverse rotation.
-
- Connect the encoder cable to the drive’s feedback port, using the manufacturer-supplied shielded cable to minimize electromagnetic interference.
-
- Ground the motor frame to the machine chassis using a dedicated ground terminal for electrical safety and noise reduction.
-
- Secure all connectors with locking clips to prevent accidental disconnection in high-vibration environments.
- Commissioning and Calibration:
-
- Pair the motor with a compatible ELAU servo drive (e.g., C200/10/1/1/1/00) and use Schneider Electric’s SoMove software to load the motor’s parameter set.
-
- Perform a drive-to-motor identification procedure to auto-tune the control loop gains, optimizing performance for the connected load.
-
- Test motor rotation in jog mode at low speed to verify correct direction and feedback functionality before full-speed operation.
-
- Calibrate the encoder zero position if precise absolute positioning is required, using the drive’s software tools.
- Operation and Maintenance:
-
- Monitor motor temperature during operation; surface temperature should not exceed 100°C to prevent insulation degradation.
-
- Check for unusual noise or vibration, which may indicate bearing wear or misalignment—address immediately to avoid damage.
-
- Inspect the shaft seal annually for oil leakage (if equipped) and replace if signs of wear are detected.
-
- Clean the motor exterior with a dry cloth; avoid using water or chemical cleaners on the housing.
-
- Lubricate bearings every 10,000 operating hours (or as specified in the maintenance manual) to extend service life.
System Introduction
The ELAU SM070-60-010-P0-45-S1-B0 functions as the mechanical output component in precision motion control systems, working in tandem with a servo drive and motion controller to deliver accurate, dynamic motion. Its integration into the system involves three key interactions:
- Power Conversion: The servo drive converts AC input power to variable-frequency AC to drive the motor’s stator windings, generating a rotating magnetic field that interacts with the permanent magnet rotor to produce torque.
- Feedback Loop: The incremental encoder provides real-time position and velocity data to the drive, enabling closed-loop control that adjusts current to maintain precise speed or position setpoints.
- Mechanical Transmission: The motor’s torque is transmitted through the shaft to the load (e.g., a conveyor, pulley, or robotic arm), with the coupling ensuring efficient power transfer while isolating the motor from load-induced vibrations.
In a small packaging machine, this motor drives a film-feeding roller, working with a C200 servo drive and PMC motion controller. The controller sends position setpoints to the drive, which adjusts the motor’s speed to feed film at a precise rate synchronized with sealing and cutting mechanisms. The encoder provides feedback to correct for any speed variations, ensuring film length accuracy of ±0.5mm—critical for consistent package sealing. The motor’s 1.0 Nm continuous torque ensures reliable operation even during peak load conditions (e.g., thick film or cold environments).
