VRAD Rotary Actuators (available for purchase or licensing)

In addition to manufacturing galvanometer-based optical scanners, ScannerMAX also manufactures, sells and licenses several patented, award-winning, open-loop VRAD rotary actuators. Our unique VRAD design offers a magnetic spring return, very wide-angle capability, low power consumption, and completely linear response. VRAD rotary actuators offer all of these advantages, while still being relatively inexpensive to manufacture.

VRAD rotary actuators have been designed in several different sides – all of them offering the same performance advantages. VRAD rotary actuators are great for moving optical components and for use as a shutter, chopper or deflector. In the banner above, you can see two of the VRAD rotary actuators we manufacture and offer for licensing.

The VRAD Advantage Explained

VRAD stands for “versatile rotary actuator device”, and our VRAD rotary actuators all utilize a revolutionary new design, that features a unique magnetic spring return, very wide-angle capability, and a linear angle vs. current profile. The high coil resistance allows for low power consumption, and access to two individual drive coils allow flexible single-supply unidirectional, or bidirectional operation as well as dual-supply operation. Front and rear shaft allow multiple points of attachment, or for the use of an encoder or position for closed-loop operation.

The key innovation contained within our VRAD rotary actuators, is our patented stator design, that uses a series of asymmetrical, interleaved laminations that are inexpensive to make, easy to assemble, and which fit together in a way that prevents the introduction of air gaps to the motors magnetic field. By re-thinking the stator design, we’ve developed a more versatile, compact, and durable rotary actuator, that can be manufactured at a much lower cost when compared to other competing products.
