Installation Instructions
TL-Series Motor Transition Plate
(Catalog Numbers TL-TRPLAT-17-23, TL-TRPLAT-23-34, and
TL-TRPLAT-34-42)
This publication provides instructions to attach the TL-Series Transition
Plates to TL-Series NEMA motors.
The TL-Series Motor Transition Plate allows a TL-Series NEMA motor
to physically replace an N-Series motor. It converts the mounting bolt
hole pattern from a TL-Series NEMA pattern to an N-Series NEMA
bolt hole pattern. This allows the original mounting holes in the
machine to be used to mount the replacement motor.
This document applies to the transition plates, motors, and mounting
hardware identified by these catalog numbers:
Catalog Number Description
Compatible Motors
From N-Series to TL-Series NEMA
TL-TRPLAT-17-23 TL-Series Transition Plate, NEMA 17 to 23 N-22xx TL-A1xxP-xxxxN
TL-TRPLAT-23-34 TL-Series Transition Plate, NEMA 23 to 34 N-34xx TL-A2xxP-xxxxN
TL-TRPLAT-34-42 TL-Series Transition Plate, NEMA 34 to 42 N-42xx TL-A25xxP-xxxxN
Transition plates are not available for the N-56xx motors.
Note: The standoff resulting from the transition plate depth reduces the shaft extension on the TL-Series NEMA motor to the nominal shaft extension of an N-Series motor.
