Allen-Bradley 145T Motor Frame Unit

Module Feature

145T is NEMA standard motor frame size from Allen-Bradley. The frame is cast iron construction with high mechanical rigidity and good heat dissipation performance. It is the mechanical housing for three-phase induction motor,provides mounting foot structure,bearing housing and heat dissipation ribs. Widely used for fan,pump,conveyor and general industrial motor equipment.

Working principle

Passive mechanical structure. The frame supports stator core and bearing assembly,conducts heat generated by motor winding to outside air,provides foot mounting interface to fix motor on machine base. No electronic components.

Onboard components

Cast iron frame body,mounting feet,heat sink ribs,bearing housing bore,terminal box mounting boss.

LED indicators

No built-in LED indicators.

Hardware self-diagnosis

Visual inspection for casting crack,deformation,surface rust; check dimensional tolerance and bearing bore condition.

Programming software

No dedicated programming software.
