The Evolution of 1326AB Architecture

The naming convention encodes mechanical and electrical configuration: the frame size, winding type, encoder resolution, and brake option are all embedded in the catalog number. For example, the 1326AB-B430E-21 designates a B-frame motor, 430 oz-in continuous stall torque rating, E-type encoder (1024 PPR incremental), and a 24 VDC holding brake. This structured nomenclature allowed system integrators to specify motors precisely without ambiguity across multi-vendor projects.

Sourcing Hard-to-Find & Obsolete 1326AB Parts

DriveKNMS operates a dedicated obsolete parts procurement function for legacy Allen-Bradley motion hardware. Our sourcing process for 1326AB motors includes:

Quality Control for the 1326AB Range

Servo motors present specific failure modes that require targeted inspection protocols. For the 1326AB series, DriveKNMS applies the following test sequence:

1. Visual and Mechanical Inspection: Shaft condition, keyway integrity, connector pin inspection for corrosion or deformation, encoder housing seal condition
2. Winding Resistance and Insulation Test: Phase-to-phase resistance balance check; insulation resistance test at 500 VDC (minimum 100 MΩ to ground)
3. Bearing Assessment: Manual rotation check for roughness, axial play measurement, and where warranted, vibration signature analysis
4. Encoder Signal Verification: Incremental encoder A/B/Z channel output verified at rated speed using a servo analyzer; signal amplitude and quadrature timing confirmed
5. Brake Function Test: 24 VDC holding brake engagement and release cycle verified; holding torque spot-checked against nameplate rating
