The LiftMaster 20-3075M-5T is an OEM replacement motor designed for select LiftMaster commercial and industrial door operators. Rated at 3/4 HP and built for 575V three-phase power, this TEFC (Totally Enclosed Fan Cooled) motor delivers reliable torque and smooth operation for overhead and rolling door systems in demanding environments. Its BM/CF configuration supports both base-mount and C-face installations, making it suitable for operators that require a footed base or direct C-face coupling to a gearbox. The TEFC enclosure helps protect the interior from dust and moisture while an external fan provides consistent cooling, ideal for warehouses, loading docks, and other commercial sites.
As an authentic LiftMaster part, the 20-3075M-5T aligns with the brand’s commercial operator designs and controls, helping ensure proper fit and performance when replacing a worn or failed drive motor. Verify compatibility by matching the operator’s parts manual and nameplate requirements to the 3/4 HP, 575V, three-phase, BM/CF, TEFC specifications of this unit. Installation should be performed by a qualified technician: confirm supply voltage and phase, follow LiftMaster wiring diagrams, set motor rotation correctly, and check coupling or belt alignment before returning the operator to service.
