The Mad360™ is a direct drive stepper motor driven, rotational system. The Mad360™ has bidirectional, continuous 360° rotation and is compatible with Mad City Labs MMP linear micropositioners and 60mm cage mount components. The Mad360™ can be used in a variety of alignment or tracking applications. Due to the direct drive mechanism, the Mad360 has a minimum step size and repeatability of 1 milliradian. The maximum speed of the Mad360™ is 20 rotations/sec. The included controller connects to a PC via a standard USB port and can be controlled via the supplied LabVIEW based software.
