Motion Service Products

Enicstra stocks the consumable and replaceable service items that keep motion systems running between major overhauls: encoder batteries for battery-backed absolute encoders, motor brake assemblies and brake-release kits, drive fan kits, dust filters and replacement covers, capacitor kits for drive refurbishment, and the small mechanical accessories (oil-seals, shaft caps, key blanks) that wear out before the motor or drive itself.

Brands carried include Allen-Bradley Kinetix and PowerFlex service kits, Yaskawa Sigma-series encoder batteries and fan assemblies, Mitsubishi MR-J service items, Siemens Sinamics and SIMOTION spare kits, and OEM-equivalent third-party batteries and capacitor kits where the original part is no longer produced. Obsolete service items — discontinued battery packs, retired brake assemblies, end-of-life fan kits — are sourced through our supplier network. Each item is inspected on receipt and ships with a 12-month functional warranty.

For an obsolete motion service item, send the OEM part number for a quote within 1–2 business days.

Choosing Motion Service Products components

Service items are where many planned-maintenance budgets either succeed or fail. Encoder batteries that go dead in storage lose absolute position references; fans that fail silently let drives overheat; brakes that wear or seize cause catastrophic stops on vertical axes. Stocking the right service items proactively avoids unplanned downtime.

Common service categories to consider:

Encoder batteries: battery-backed absolute encoders need replacement batteries on a typical 5-year schedule (sometimes shorter under hot operation). The battery type is OEM-specific — Yaskawa SGS-series, Mitsubishi MR-BAT, Siemens 6FX/6SL-series
Motor brake assemblies: holding brakes on vertical axes wear from repeated dynamic stops. Replacement assemblies are motor-frame-specific
Drive fans: drive cooling fans fail before the drive electronics. Replacement fans are part-number-coded to the drive frame
Dust filters and covers: drive intake filters, cabinet filters, and shaft seal covers — consumables in dusty environments
Capacitor kits: for older drives, DC-bus capacitors degrade over time and are replaceable as a kit with bleeder resistors
Mechanical small parts: shaft oil seals, key blanks, dust caps, and connector boots

Common gotchas: encoder batteries in storage drain over years — surplus motors with absolute encoders may need a fresh battery before being put into service. Drive fans are not generic; the OEM fan has matched bearings and airflow for the heatsink design, and a substitute fan with different airflow can cause thermal trips even at light load. Brake assemblies are motor-frame-specific and the brake gap is critical — a replacement assembly may need shimming during installation. Capacitor kits for older drives sometimes require capacitor-bank re-forming after installation; follow the OEM procedure.

Typical situations: scheduled maintenance turnaround on a packaging line, spare-bank stocking for a critical machine, post-flood or post-fire restoration of motion equipment, and storage refresh of long-idle backup motors.

For obsolete motion service items, send the OEM part number for a sourcing quote.

Related categories Frequently asked questions

Do you stock encoder batteries for legacy servo motors?

Yes. Yaskawa SGS-series, Mitsubishi MR-BAT, Siemens 6FX2003, and Allen-Bradley Kinetix encoder battery packs are stocked or sourced. OEM-equivalent batteries are available for some long-discontinued types.

How long do encoder batteries last?

Typically 3–5 years of continuous service, less under high temperature. In storage with the motor powered off, batteries drain faster. Plan a replacement schedule based on the OEM's published battery life and your operating temperature.

Can I use a generic 3V lithium battery in place of the OEM battery?

Sometimes the cell chemistry is identical, but the connector and form factor are OEM-specific. Wiring a generic cell to the OEM connector is sometimes done in the field — proceed at your own risk; warranty is on OEM-equivalent batteries we supply, not on customer-made substitutes.

Do you stock obsolete drive fan kits?

Yes. Discontinued PowerFlex, A1000, MR-J3 fan assemblies, and similar end-of-life service items are sourced through our supplier network.

Are capacitor kits worth it on an older drive?

For drives 10+ years old that have been in service continuously, yes — DC-bus capacitor degradation causes voltage ripple that stresses the IGBT modules. A capacitor refresh can extend drive life significantly when done before failure.

What is the warranty?

12 months functional warranty on service items. Batteries are covered against early failure but not against gradual depletion from extended storage before installation.
