ABSTRACT:
A two speed drive for an apparatus which uses DC electrically actuated oil shear brake/clutch units is disclosed. The two speed drive directly connects the output to a first input for high speed movement using a DC voltage coil to actuate the clutch/brake for low speed operation. The output is connected to a second input through a gearing system using another DC voltage coil to actuate the clutch/brake. The DC voltage coils provide a repeatable and variable acceleration curve for exact operation of the drive.
