Micro Dyne Data Sheet Motor Characteristics Measured/ Calculated: • Torque • Speed • Amps • Volts • Horsepower • Efficiency • Input Watts • Output Watts FEATURES • DESIGNED SPECIFICALLY for miniature and micro motors • Torque: Easily convertible from 2.0 mN-m to 4.0 mN-m (0.28 oz-in to 0.57 oz-in) • Speed: up to 100,000 rpm • Low inertia • Sold as a complete, out-of-the-box motor testing system. Components include: • Hysteresis Dynamometer: provides precise torque loading independent of shaft speed • Motor Fixture: accommodates motors from 5 mm to 30 mm in diameter. • Dedicated Electronics: all-in-one dynamometer controller, DC wattmeter, power relay and USB interface • Comprehensive Motor Testing Software • Easy-to-use calibration software • All necessary connection cables DESCRIPTION With over 50 years’ experience in dynamometer design and torque measurement, Magtrol has revolutionized the industry. Magtrol’s NEW Micro Dyne, capable of measuring extremely low torques (2.0 mN-m can be resolved to 0.0004 mN-m), is designed EXCLUSIVELY for testing miniature and micro (low-torque) motors. For the utmost convenience, the Micro Dyne is packaged as a COMPLETE MOTOR TESTING SYSTEM. Everything that is needed to accurately and efficiently test miniature motors and micro motors is included with the purchase of a Magtrol Micro Dyne. The only component that needs to be supplied by the customer is a laptop or desktop personal computer and motor power supply. APPLICATIONS Magtrol motor test systems can be found in test labs, at inspection stations, and on the manufacturing floors of most of the world’s leading motor manufacturers. The Micro Dyne system is used exclusively for closed-loop testing of miniature motors and micro motors used in low-torque/highspeed applications. Motor sub-types include, but are not limited to, the following: • Brushed and brushless DC motors • Gearmotors • Brushless DC servomotors • Vibrator motors • Miniature air motors These mini/micro motors are used in a diverse range of industries and products, including: • Medical and laboratory equipment • Robotics and automation • Toys • Handheld communication devices • Audio/video equipment • Optics and photonics • Aerospace and defense • Security and instrumentation • Industrial machinery

Micro Dyne Motor Fixture O System InformationSYSTEM COMPONENTS Dynamometer The Micro Dyne dynamometer absorbs power with Magtrol’s unique Hysteresis Braking System. Because it does not require speed to create torque, the dynamometer can conduct a full motor ramp—from free-run to locked rotor. In addition to a dedicated motor fixture, the dynamometer base plate also includes leveling knobs and motor power terminals. The housing of the dynamometer protects all the moving parts of the brake. Electronic Unit At the hub of the Micro Dyne system is a multifunctional electronic unit. The unit employs DSP...

O Specifications Micro Dyne The Micro Dyne offers two different torque configurations in one unit. Depending on the motor’s maximum torque rating, the user can easily switch between the 2.0 mN-m and 4.0 mN-m torque settings via the dynamometer’s rear access panel. The ratings are the same for either configuration.
