Products Description
Baldor M3157T Three Phase Induction Motor Unit

Module Feature
M3157T belongs to Baldor general-purpose three-phase squirrel-cage induction motor. NEMA 145T steel foot mount frame,rated 2HP,1800RPM,208-230/460VAC,TEFC totally enclosed fan cooled construction. NEMA Design B torque characteristic,Class F insulation,service factor 1.15,continuous duty rating. Widely used on fans,pumps,blowers and material handling equipment.
Working principle
Three-phase alternating current generates rotating magnetic field inside stator winding,induces current in squirrel-cage rotor to produce driving torque. Shaft-mounted fan delivers forced air cooling for sealed TEFC housing to dissipate winding heat.
Onboard components
Steel motor frame,stator winding,squirrel-cage rotor assembly,ball bearings,shaft cooling fan,fan cover,terminal box,keyed output shaft.
LED indicators
No built-in LED indicators.
Hardware self-diagnosis
Winding continuity & insulation resistance test,bearing noise and temperature check,visual inspection for fan damage and housing corrosion,vibration test.
Programming software
No dedicated programming software.
