Allen-Bradley MPL-A310F-HJ22AA MP-Series Motor

Description

Product Introduction & Engineering Value

The MPL-A310F-HJ22AA is a 200 V class MP-Series low-inertia servo motor with a 100 mm frame and 25.4 mm magnet stack. It delivers a rated speed of 3000 rpm and uses a 2000-line incremental encoder for precise feedback. The shaft is keyed with no shaft seal, connectors are circular bayonet facing the shaft, and the motor ships without a holding brake.

Designed for Kinetix servo drives, this motor provides the rapid acceleration and compact size needed on packaging, converting, and material-handling axes where inertia matching and dynamic response matter. IEC metric mounting and standard factory options allow straightforward mechanical integration.

Technical Specifications

Field Application & The “Trench” Experience

A Midwest packaging OEM had a high-speed cartoner axis that kept overshooting during product changeovers. The original motor’s encoder had degraded and the inertia match was marginal. Swapping in an MPL-A310F-HJ22AA restored the 2000-line feedback, tightened the servo loop on a Kinetix 5500 drive, and brought the axis back to spec within a single shift. The keyed shaft and bayonet connectors matched the existing coupling and cable set exactly.

Niche placements that fit this exact model:

• High-speed labeling or cartoning axis requiring low inertia and 3000 rpm capability.
• Electronic assembly or pick-and-place mechanism where compact 100 mm frame size is critical.
• Converting-line dancer or feed roll driven by a Kinetix servo that still uses incremental encoder feedback.

Transparency SOP: QA & Testing

Each motor is inspected for physical condition of the housing, shaft, and connectors. Electrical continuity and insulation resistance of the windings are verified. The incremental encoder is tested for correct pulse count and signal integrity across a full rotation. Shaft run-out and key fit are checked. When possible the motor is spun on a compatible Kinetix drive to confirm smooth operation, feedback quality, and absence of unusual noise or vibration. Only units that pass the complete sequence are released as New Surplus or Refurbished stock.

The Veteran’s Tech Trap Guide

⚠️ Shaft seal omission – This catalog ships without a shaft seal. For IP66 or wash-down environments you must add the correct seal kit (MPL-SSN-F63F75 or equivalent). Running without it will allow contaminants into the bearings.

⚠️ Encoder type mismatch – The “H” feedback is a 2000-line incremental encoder. Do not substitute a multi-turn absolute version without updating the drive configuration and possibly the feedback cable.

PRO TIP: Always verify the motor nameplate against the drive’s motor database. An incorrect catalog string in the Kinetix configuration will produce wrong torque and velocity scaling even if the physical motor is correct.

Dynamic FAQ

Q: Is the MPL-A310F-HJ22AA still available new from Rockwell? A: Availability of specific MP-Series configurations varies; many legacy feedback and connector combinations are no longer stocked as new. Functional New Surplus and refurbished units remain the practical source for exact replacements.

Q: Does this motor include a holding brake? A: No. The “2” in the catalog string indicates no brake. If a brake is required, a different catalog number must be selected.

Q: What feedback resolution does the encoder provide? A: 2000 lines per revolution incremental. With quadrature this yields 8000 counts per revolution.

Q: Can this motor be used with a Kinetix 5700 or 5500 drive? A: Yes. It is compatible with the Kinetix 5500, 5700, 6000, 6200/6500, and earlier Kinetix platforms when the correct motor data and feedback type are configured.

Q: What warranty and authenticity documentation come with New Surplus or Refurbished stock? A: Units ship with functional test records, clear origin marking (New Surplus or Refurbished), nameplate verification, and a standard parts-and-workmanship warranty.
