The SMAC Stack

On May 15, 2018, SMAC Moving Coil Actuators introduced the innovative, new SMAC Stack. SMAC mounts a series of actuators together on a single bottom plate.

This is particularly useful when the customer has a requirement for a number of precisely spaced units. (For example, in electronic assembly, packaging / food processing divert or eject, etc). The SMAC Stack allows actuator placement as desired - in terms of pitch or staggering. The stack also can be IP enclosed. Controllers can be built in as well as the Master controller that coordinates all the individual controllers as well as interfaces with various protocols like EtherCat or EthernetIP. The SMAC Stack eliminates most cables because you only need one power cable and one signal cable to stack up to 12 actuators.

And the stack is actually a lower cost approach since the number of individual parts - bottom plates and mag housings - are replaced by just 2 parts. 

Further details coming soon.

SMAC Direct Drive Servo Motor Robotic Finger

At the Automate 2015 show in Chicago, SMAC Moving Coil Actuators introduced a prototype version of the world's first direct drive servo motor robotic finger, acknowledged as a technological breakthrough by a leading European technical university. It is shown here operating a Samsung Galaxy touchscreen phone. SMAC expects an early 2016 release to be shortly followed by a robotic thumb and ultimately the first true functional robotic hand capable of reproducing work done by human hands.

The first motor is a 25 mm-diameter servo "partial" motor and is equipped with an SMAC rotary encoder with 15.5K counts per revolution. It achieves a high torque/diameter ratio due to the proprietary magnetic circuit design as well as the coil design. Intellectual property rights have been addressed. This motor acts as the PIP joint.

Another larger motor, 35 mm diameter, acts as the 2nd joint (MCP FLex). It puts out a torque of 630 mNm and thus can exert a resultant force of 7N at the tip. Both motors move 45 degrees as the human joints do.

The 3rd motor operates as a third joint (MCP ab/ad). This is the joint that moves side to side. This motion is based on SMAC’s moving coil linear design and already meets the required parameters.

These motors have been integrated into a structure that allows them to operate and cover the same movement capability as a human’s finger. The structure weighs approximately 350 grams and is physically about 1.5 x larger than the average male finger.

Watch the presentation given at Hannover Messe 2015.
