These Conversion Bases are designed to allow NEMA “T” frame motors to
be used where corresponding NEMA “U” frame motors have been applied.
Consisting of right and left hand pieces that fit to existing mounting studs
positioned for “U” frame motors. The “T” frame motor is mounted to the
pieces resulting in compensation for the difference in motor height, shaft
position and mounting hole between the previous “U” frame motor and the
replacement “T” frame motor. Made of the same top quality material as the
adjustable motor bases.
Conversion Bases
NOTE:
Dimensions are for one piece. Two pieces supplied. Design is for horizontal mounting. Motor shimming may be required for direct drive applications.
