Micro Dyne System
Finally… a Micro Dyne system designed specifically for your micro motors! 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 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 a motor power supply.
- 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
- Banner D10 Expert™ Fiber Optic Sensor (located on the side of the electronics box on older models)
- Keyence FS-N10 Series Digital Fiber Sensor (located inside the dynamometer enclosure of the new model)
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, wattmeter, power relay and USB interface
- Comprehensive Motor Testing Software: new version of Magtrol’s M‑TEST 7, updated for the Micro Dyne
- Easy-to-use calibration software
- All necessary connection cables
- Calibration weights: 5 g and 10 g
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.
