The Centripetal Force Apparatus Motor Accessory Kit (GDX-CFA-MAK) is not compatible with the Centripetal Force Apparatus (CFA). The orientation of the 3-step pulley and attachment to the structure do not allow for this combination.

Manually rotating the shaft up to speed and allowing it slow through a range of angular velocity is our recommended method of collecting data with the both the Centripetal Force Apparatus (CFA) and Go Direct^® Centripetal Force System (GDX-CFA). The Motor Accessory Kit provides additional isolation of variables for the Go Direct version of this tool.

The Centripetal Force Apparatus Motor Accessory Kit (GDX-CFA-MAK) is only compatible with the Go Direct^® Centripetal Force System (GDX-CFA).
