ELAU SM-070-60-020-P4-55-S1-B1 PacDrive Servo Motor

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The ELAU SM-070-60-020-P4-55-S1-B1 is a high-precision AC synchronous servo motor designed specifically for the PacDrive M system. It excels in packaging, bottling, and material handling applications where rapid acceleration and precise synchronization are required. Integrating seamlessly with MC-4 and PacDrive controllers, this motor provides high power density in a compact 70 mm frame size.

From a supply chain perspective, these motors are increasingly difficult to source through standard OEM channels. Procurement of this unit as New Surplus is a strategic move to lower the Total Cost of Ownership (TCO). While refurbished motors risk insulation breakdown or bearing fatigue, our New Surplus units eliminate the high cost of unplanned downtime. Maintaining 1–2 units as buffer stock is an essential insurance policy against long lead times for legacy motion control hardware.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

Begin by performing a full lock-out/tag-out (LOTO) of the machine’s main power. Ensure you have an ESD wrist strap grounded to the machine frame. Before removing the old motor, photograph the cable routing and the nameplate of the failed unit to verify the exact sub-variant matches the SM-070-60-020-P4-55-S1-B1.

Stage 2: Removal

Disconnect the power and encoder cables carefully; do not pull on the wires. Loosen the mounting bolts on the motor flange. If the motor is coupled to a gearbox or belt drive, ensure the load is supported to prevent mechanical shifts. Slide the motor out horizontally to avoid damaging the mounting face or bending the shaft.

Stage 3: Installation (Clone & Seat)

Verify the new motor’s shaft is clean and free of debris. If the old motor used a specific keyway (though this model is typically smooth shaft), ensure compatibility. Seat the motor firmly against the flange and torque the mounting bolts to the manufacturer’s specification. Reconnect the Hiperface encoder and power cables, ensuring the connectors are fully seated and locked.

Stage 4: Power-On & Testing

Power the controller and check for “Feedback Error” or “Commutation” faults. Since the Hiperface encoder stores motor parameters, the drive should recognize the SM-070 motor automatically. Perform a slow-speed jog test to verify rotation direction before engaging the 24 V holding brake for full-speed production logic.

Firmware/Software Versions & Upgrade Notes

• Feedback Compatibility: This motor utilizes the SinCos Hiperface interface. It is compatible with ELAU PacDrive MA-4, MC-4, and PacDrive 3 systems (with appropriate adapter cables).
• Electronic Nameplate: The motor contains an internal EEPROM. Upon connection, the drive reads the motor type and commutation offset automatically. No manual firmware “loading” into the motor is required.
• Version Caution: Ensure your controller’s firmware version supports the SM series motor library. Swapping a newer SM motor into an extremely legacy system (pre-2005) may require a minor library update in EPAS-4.

Frequently Asked Questions (FAQ)

Is this motor actually brand new or just repainted?

This is 100% New Surplus. It has never been installed in a production environment. Unlike “refurbished” units that may have worn bearings or aging windings, this motor comes from climate-controlled surplus inventory, ensuring original OEM reliability and a full service life.

Do I need to program the motor after installation?

No. The SM-070 series features an integrated electronic nameplate via the Hiperface encoder. When you connect it to your ELAU drive, the system automatically detects the motor parameters and commutation data. You only need to verify your software axis scaling.

Why should I buy this instead of a cheaper refurbished unit?

A refurbished motor is a gamble. Components like internal capacitors in the encoder or the winding insulation degrade over time. In a high-speed packaging line, a motor failure can cost thousands in lost throughput per hour. Buying New Surplus is a one-time investment that guarantees the highest MTBF (Mean Time Between Failure).

Does this unit include the holding brake?

Yes, the “B1” designation in the model number SM-070-60-020-P4-55-S1-B1 confirms this unit is equipped with an integrated 24 VDC electromagnetic holding brake.

What is the warranty on a New Surplus ELAU motor?

We provide a comprehensive 12-month warranty on this motor. Because it is New Surplus, we stand behind the hardware’s integrity just as if it came directly from the factory floor.
