Baldor M1705T Two-Speed Induction Motor Unit

Module Feature

M1705T belongs to Baldor multi-speed series three-phase squirrel-cage induction motor,NEMA 145TC cast iron frame,foot mount plus C-face flange. Rated 1.5HP dual speed 1800/900RPM,460VAC,TEFC totally enclosed fan cooled,constant torque single winding design,Design B,Class F insulation,service factor 1.15. Widely used for fans,blowers,conveyors and other equipment requiring two fixed operating speeds.

Working principle

Change winding connection mode to switch pole pairs to realize two different synchronous speeds. Shaft-mounted fan provides forced air cooling inside sealed TEFC housing. Dual mounting design supports foot base installation or direct C-face coupling to reducers and pumps.

Onboard components

Cast iron frame,multi-tap stator winding,squirrel-cage rotor assembly,ball bearings,cooling fan,fan cover,multi-terminal terminal box,keyed output shaft.

LED indicators

No built-in LED indicators.

Hardware self-diagnosis

Winding continuity & insulation resistance test,bearing noise and temperature inspection,terminal wiring check,vibration measurement.

Programming software

No dedicated programming software.
