Description
Allen-Bradley VPL-B1304E-PJ14AA – Low-inertia servo motor for fast, precise machine axes
The Allen‑Bradley VPL-B1304E-PJ14AA belongs to the Kinetix VPL family of low-inertia rotary servomotors. From my experience, this 130 mm frame is a sweet spot for high-throughput packaging axes, indexing conveyors, and pick-and-place heads where quick acceleration and tight positioning are essential. You might notice that the VPL series uses single-cable technology with an integrated digital encoder, which typically cuts wiring time and simplifies cabinet layouts.

Key Features
- Low-inertia rotor – Designed for rapid start/stop and high cycle rates on servo axes that need sharp responsiveness.
- Single-cable motor/encoder – Power and high‑resolution feedback share one cable, which typically reduces cable count and installation time.
- High-resolution absolute feedback – Digital absolute encoder enables precise positioning without homing in many cases after power-up.
- 130 mm square flange – A compact footprint for medium‑torque applications and straightforward mechanical replacement on IEC/NEMA-style mounts.
- Optimized for Kinetix drives – Pairs well with Kinetix 5300/5500/5700, simplifying tuning and leveraging drive-based safety and diagnostics.
- Industrial protection – When correctly sealed and cabled, VPL motors typically achieve IP65 at the shaft (with seal) and robust resistance to shop-floor contaminants.
A packaging OEM told us they swapped to a VPL-B1304E on a carton erector axis and shaved ~18% off cycle time, mainly due to the motor’s low inertia and easier single-cable routing.
Technical Specifications
| Brand / Model | Allen‑Bradley VPL-B1304E-PJ14AA (Kinetix VPL series, low‑inertia rotary servo motor) |
| HS Code | 8501.52 – AC motors of an output exceeding 750 W but not exceeding 75 kW |
| Power Requirements | For use with Kinetix servo drives (typically 230 V-class). Drive current and bus voltage depend on the selected Kinetix model and duty profile. |
| Dimensions & Weight | 130 mm square flange frame; “04” stack length variant in the 130 frame. Typical length ~200–240 mm and weight ~8–11 kg, depending on options. |
| Operating Temperature | 0 to +40 °C ambient (standard industrial environment) |
| Signal I/O Types | Integrated absolute digital encoder via single-cable interface; three-phase motor power. |
| Communication Interfaces | Feedback communication embedded in the single-cable link to Kinetix drives (no external fieldbus on the motor itself). |
| Installation Method | Front-flange mount (IEC-style 130 mm). Keyed shaft; optional shaft seal for IP65 at the shaft when used with the correct coupling and protection. |
Related and Supporting Products
- VPL-B1303E-… – Same frame with a different winding/torque rating; typically lower continuous torque than the “04” stack.
- VPL-B1004E-… – Smaller 100 mm frame for tight spaces and lower inertia loads.
- VPF series (food-grade) – For washdown or food applications where hygienic finishes are required.
- Kinetix 5300 / 5500 / 5700 drives – Matched servo drives that support the VPL single-cable feedback architecture.
- 2090 single-cable assemblies – Power/feedback hybrid cables sized to your run length and bend radius; strain reliefs and right-angle heads help with shallow enclosures.
- Precision gearboxes (130 mm adapters) – For higher torque at lower speed while maintaining servo stiffness.
Installation & Maintenance
- Cabinet and wiring – Use Kinetix-approved single-cable assemblies; route power apart from signal where possible. Maintain proper shielding and grounding to minimize EMI.
- Mounting and alignment – Align couplings to avoid excessive radial/axial loads. If using a shaft seal, lightly lubricate and protect from abrasive dust.
- Ventilation – Provide adequate airflow around the motor body. In most cases, keeping the ambient below 40 °C preserves torque margins.
- Safety – Lock out the drive DC bus before service. Verify the motor nameplate against the drive data set to avoid mismatched tuning.
- Routine checks – Inspect connectors and cable jackets, re-torque mounting hardware, and review drive logs for thermal or following error trends. Firmware updates are applied at the drive level.
- Brake option – This code appears to include brake on some variants; confirm by nameplate if a holding brake is required for vertical axes.
Quality & Certifications
- Typically CE marked and cULus certified for industrial use
- RoHS compliant; manufacturer quality system aligned with ISO standards
- Manufacturer’s standard product warranty; our supply warranty is 365 days from shipment
Quick sizing tip: the “1304” winding is often chosen when you need a balance of continuous torque and fast accelerations on mid-mass loads. If your axis has a high reflected inertia, consider adding a gearbox or checking a higher-torque VPL variant for thermal headroom.
