± Same as UP3 except:

 

 

 

± Has an AG type armature with an AF commutator and

 

 

 

a standard AUP flash ring.

 

 

 

± Has AG type commutating coils and poles with brazed

 

 

 

instead of bolted connections.

 

 

 

± Has air vents in the drive±end framehead

 

 

 

± Has a frame specially machined for mounting the

 

 

 

customer gearbox at the drive end.

 

 

 

± Has a different drive±end grease arrangement.

 

 

 

± Has rubber hardtop brushes instead of regular duplex

 

 

 

brushes.

 

 

 

 

 

 

752US2

Same as US1 except:

 

 

 

± Has an improved commutator±end bearing assembly and an

 

 

 

ABS±certified armature shaft.

 

 

 

 

 

 

752AUP1

This is a series motor with the following distinctions:

 

 

 

± Has internal greasing tubes for both drive end and

 

 

 

commutator±end bearings

 

 

 

± Has a double±ended shaft.

 

 

 

 

 

 

752AUP2

Same as AUP1 except:

 

 

 

± Has armored cable

 

 

 

± Has no grease tubes at commutator end

 

 

 

± Mounting feet have dowel holes for vertical mounting.
