Aluminium DIY Reciprocating Cycle Linear Actuator 12V 15Rpm Big Torque Stroke 12Mm 16Mm 20Mm Adjustable For DIY Design Shale Shaker

This rotation to translation mechanism was used to calibrate the acceleration vs. the voltage output of an accelerometer. This particular unit runs at a low rpm speed using a geared motor. Ashtonishly, the mechanism is well built and the offset circular to linear linkage offers three different radius positions which allows three different linear displacements. We purchased (separately) a 550 rpm motor that fit the apparatus to allow for a faster rpm. You and your students will enjoy using this mechanism. The physics behind the relationship between rotation angle and translation is fastenating.

very nicely made. I like it.

You would probably want a something with a more powerful motor. It stalls out with a light load.

Did not fit my needs but that is on me. Miss calculation on my part.

Works as stated. Good quality. Wish the motor was stronger. Still giving 5 stars, cause it is exactly as it was described.
