Schneider ELAU SM140-30-370-P1-45-S1-B1 Servo Motor 19204304-004

Core Features

• ✓ Slip-Free Keyed Shaft: The feather groove (keyway) design provides a positive, rigid mechanical connection to pulleys or gearboxes. This is crucial for preventing slippage during aggressive acceleration, sudden stops, or heavy load reversals.
• ✓ Integrated Safety Brake: Built with a highly reliable holding brake that automatically clamps down when power is removed, ensuring suspended loads or robotic arms remain safely locked in place during downtime or emergencies.
• ✓ Seamless PacDrive Integration: Designed to operate flawlessly within Schneider Electric's PacDrive ecosystem. The motor's electronic nameplate allows the drive to automatically read its parameters for quick, error-free commissioning.
• ✓ Precision SinCos Feedback: Equipped with a single-turn SinCos encoder that delivers continuous, high-resolution positional data back to the controller, resulting in exceptionally smooth and precise dynamic movements.

Q: Why choose the keyed shaft (P1) variant over a smooth shaft?

A: The feather groove (keyed) shaft ensures a solid mechanical lock between the motor and the driven load. It is highly recommended for applications with frequent starts, stops, or reversing movements where a smooth shaft might slip under peak torque.

Q: How does the integrated holding brake (B1) operate?

A: The built-in brake is a fail-safe mechanism. It is normally engaged and only releases when power is applied to the motor. It is designed specifically to hold a stationary position (like securing a vertical Z-axis load) and should not be used for dynamic braking while the motor is spinning.

Q: Is this motor ready to drop into an existing PacDrive setup?

A: Yes, part number 19204304-004 is a direct fit for the PacDrive ecosystem. The drive system will automatically identify the motor's data via its encoder connection for swift configuration.
