These brand-spanking new 12VDC motors are made to move automobile seats but are willing to change.
They spin at approx 190 rpm, draw 1.5A no load, and stall at approx 25A.
Threaded shaft is at a right angle and is 4-1/8" x 7/16". Shaft thread is non-standard, so treat it as a smooth shaft and mount pulley or gear with a setscrew.
Measures 5-5/8" x 2-1/2" x 2-1/2" overall, not counting the shaft, and has power terminals opposite the gearbox with (2) 1/4" mounting holes opposite the shaft.
