MICRO DYNE MICRO DYNE MOTOR TESTING SYSTEM 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 ▪ Power: 4 W ▪ 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 Fig. 1: Micro Dyne Motor Testing System ▪ Comprehensive Motor Testing Software ▪ Easy-to-use calibration software ▪ All necessary connection cables ▪ Calibration weights: 5 g and 10 g 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. Motor Characteristics Measured/Calculated: ▪ Torque ▪ Speed ▪ Amps ▪ Volts ▪ Horsepower ▪ Efficiency ▪ Input Watts ▪ Output Watts © 2020 MAGTROL | Due to continual product development, Magtrol reserves the right to modify specifications with

MICRO DYNE 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/high-speed applications. Motor sub-types include, but are not limited to, the following: 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 ▪ Brushed...

MICRO DYNE OPERATING PRINCIPLES SPEED MEASUREMENT TORQUE MEASUREMENT The Micro Dyne contains a reflective fiber optic speed pickup. Each rotor slot that passes by the sensing end of the fiber optic generates an electronic pulse, which is then converted to a speed reading (in rpm). A hysteresis brake is used to develop a resistance to rotation of a mechanical shaft. A torsional force is produced by the test motor and applied to the brake’s rotor-shaft assembly. Reaction torque is measured by the angle of the brake pendulum assembly and is interpreted by the Micro Dyne system software (M-TEST 7)....
