Foredom M.SR-SCT M.SR Hang-Up Motor with SCT-1 Cast Iron Foot Pedal Speed Control, 115v Our best advice is to go with a model within the Series SR. Series SR flex shaft motors are 1/6 HP, run in forward and reverse at speeds up to 18,000 RPM, and offer all of the power and speed needed to accomplish most every job. Keep in mind that our motors are rated at continuous duty or maximum efficiency and NOT maximum output. If weadopted themax output ratingused by other manufacturers, it wouldqualify as 1/5 or 1/4HP. M.SR Motor is a hang up motor with a standard 39" long key-tip shaft for connecting to any of Foredom’s interchangeable, quick disconnecthandpieces. C.SCT-1 Speed Control offers the same electronics and smooth control as the C.FCT-1 but in a much heavier, cast iron housing. The added weight eliminates any unexpected movement of the control along the floor. The bottom surface of the speed control is covered with non-skid material.
