Miga Motor Company: Modern Motion


Shape Memory Actuator Applications
        Miga Motor Product Line

Miga Motor Company is the world leader in
Shape Memory Alloy (SMA) actuator development, and has developed the first commercially available line of modular SMA actuators. Originally designed in the mid 1990's as ultralightweight mechanisms for spacecraft, Miga products are now available to economically replace motors and solenoids in many applications. Please refer to the Downloads page for Application Notes, Movies, Data Sheets, etc.

MigaOne Smart Actuator
The MigaOne™ is the first of our actuators to be built upon a PCB substrate, and the first volume-ready actuator from Miga. MigaOne™ provides 2.5 pounds of force with 3/8" of stroke. The MigaOne™ retails for $39.95 and is available directly from the factory or from our online retailers: SparkFun, GoTronic, RobotShop, and SCM International. Now available online at the Miga Store.
Dash4 Smart Actuator The newest actuator to join the Miga lineup is the Dash4™, providing over 1.75 pounds of actuation force and a stroke of 0.23". The built-in limit switch allows for safe operation over a wide range of voltage (and speed) when used along with the MAD-v5. The Dash4™ is just under an inch wide, and less than 0.1" thick! The Dash4™ retails for $29.95 and is available now. Available online at the Miga Store.
MOBI Smart Actuator The new MOBI™ actuator is currently available only in limited quantity by special order at $99.95 each. The MOBI™ produces one pound of output force with 0.15" stroke, weighs just 0.09 ounces, and is only 0.5" wide x 1.125" long x 0.080" thick!
Miga Analog Driver
The Miga Analog Driver v5 (MAD-v5) is a MOSFET switch designed to safely power Miga actuators across a wide range of speeds or input voltages. The MAD-v5 allows push-button operation, or an external logic GATE signal to actuate the MigaOne™, Dash4™, MOBI™, or NM70R-6P until the end-of-travel is reached. The MAD-v5 then cuts power momentarily, preventing overheating of the SMA wires. The MAD-v5 retails for $13.95. Available online at the Miga Store.
NM70-Super SMA Actuators Weighing just over one gram, the NM70-Super provides 4mm (0.16") of stroke with 70 grams (~2.5 oz.) output force. The surplus NanoMuscle NM70-Super is available in large quantities. Prices start at $9.95 each. The NM70-Supers are available at the online Miga Store.
Rotary NM70 SMA Actuators Weighing in at 4.2 grams, surplus NanoMuscle Rotary actuators are now available directly from Miga Motor Company. These spring-loaded rotary actuators provide 60˚ of rotation by encapsulating the linear NM70-Super above in a plastic body with a cam-action rotary output. The NM70R comes in 2- and 6-pin versions, the 6-pin providing greater control authority. Operating voltage is ~3-6V. Prices start at $9.95 each. See a demo movie here. Available online at the Miga Store.
Arduino USB Controller The Arduino USB is an open-source electronics prototyping platform based on flexible, easy-to-use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in creating interactive objects or environments. Available here or from SparkFun, the Arduino makes it easy and fun to control Miga Motion in many interesting ways.  See the MigaOne/Arduino Tutorial here. The Arduino is available from Miga at $39.95. Available online at the Miga Store.
DM01 Linear SMA Actuator The DM01-Series actuators provide PUSH or PULL motion with up to 4.5 pounds of force in a 0.7 ounce package. The DM01 is available in three force ranges starting at $119. See the DM01 Application Notes for additional details here.
DM01 Linear SMA Actuator -UHT The UHT-Blue is DM01-style actuator with an all aluminum body and Ultra-High-Temperature (UHT) NiTiPd30 Shape Memory Alloy Wire currently under development. The UHT-Blue can operate safely in enviromnents over 200˚C!  Available in very limited supply, the UHT-Blue is $599. Call the factory to order.
DM01 Linear SMA Actuator -Gold The NForceTM is a high force (up to 16 lbf) Dorsal-style actuator. Weighing just over an ounce, the NForceTM provides either PUSH or PULL stroke (depending on the Dorsal Fin mounting orientation ) of 0.45" using a Lost Motion Output. Available only in the Gold Aluminum body at $429. Call the factory to order.
DM01 Linear SMA Actuator - Dorsal The DM01 DorsalTM is a DM01-Series PULL actuator that allows for side attachment instead of the original output shaft. The DorsalTM can be used in both PUSH and PULL modes. The DorsalTM is available in two force ranges starting at $119. Call the factory to order.
Miga Micro-controllers Miga Motor Company has focused tremendous effort on micro-controller development over the past several years. Once provided only to customers involved in custom development efforts, these powerful PIC-based processors are available pre-programmed for safe operation in several modes, with numerous I/O options. The patent pending micro-controller solutions start at $289.
