Reliance 184T NEMA Motor Frame Unit

Module Feature

184T is Baldor-Reliance NEMA standard T-type motor frame. It defines unified mechanical installation footprint, shaft size, mounting hole layout and center height for induction motors. It is widely matched with 5HP 4-pole general-purpose motors under NEMA specification. Cast iron frame structure, high rigidity, good vibration resistance, compatible with TEFC, ODP enclosure types. Suitable for pumps, fans, conveyors and general industrial driving equipment.

Working principle

This item is only a mechanical frame standard, without electromagnetic operation principle. It provides fixed installation datum for stator core, rotor, bearing assembly and end cover. It ensures interchangeability among motors of the same frame size from Baldor-Reliance and other NEMA compliant manufacturers.

Onboard components

Cast iron frame base, bearing housing mounting seat, foot mounting lugs, tapped mounting holes, shaft center positioning datum.

LED indicators

No onboard LED indicators.

Hardware self-diagnosis

Check frame flatness, inspect mounting thread damage, verify bearing seat bore deformation, check crack and casting defect on frame surface.

Programming software

No configuration software, purely mechanical standard dimension component.

Electrical & Process Parameters

Model:184T Brand:Baldor-Reliance Device type:NEMA Standard Motor Frame Matching Power:5HP (4 pole typical) Shaft Diameter:1.125 in Standard:NEMA MG1 Function:Mechanical mounting base for AC induction motor

Mechanical & Structure

Mounting:Foot mount Protection class:IP54 (depends on matched motor enclosure) Housing:Cast iron frame

Environmental

Operating temperature:-20℃ ~ +80℃ Storage temperature:-30℃ ~ +85℃ Ambient humidity:5~95% non-condensing Certification:NEMA MG1 industrial standard compliant Status: Baldor-Reliance original NEMA 184T frame

Installation

Fix the frame on rigid base by mounting feet. Install stator assembly, bearing and end cover according to NEMA assembly tolerance. Keep frame installation surface level to avoid additional bearing stress.

Interface

Foot mounting threaded holes, front and rear bearing housing fitting interface, stator press-fit inner cavity.

Diagnostic

Vibration excess: uneven mounting surface or frame deformation. Bearing heating abnormally: frame bearing bore out of tolerance. Mounting mismatch: wrong frame size selected.
