AUVSI 2014 - Highly Dynamic Brushless DC motors

Compact yet powerful In automation and robotics, many applications are characterized by high energy and high torque at the same time. Spatial restrictions also mean that drives must be short, have a long service life and be maintenance-free.

In automation and robotics, many applications are characterized by high energy and high torque at the same time. Spatial restrictions also mean that drives must be short, have a long service life and be maintenance-free. The newly redesigned EC-i motors from maxon motors offer solutions that fit these requirements perfectly.


These brushless DC motors have several key advantages: low inertia, minimal detent, robust bearings and compact construction. The use of high-powered permanent magnets ensures high power density, providing great speed stability under load.

These motors are available in 40 mm diameter and in two lengths, namely 26 mm (50 Watt) and 36 mm (70 Watt). The modular system with gearheads, encoders and controllers from the maxon delivery program offers a large number of possible combinations.

EC-i motors are ideally suited for applications that require maximum drive in a minimum space. Typical areas of application are robotics, industrial automation and security technology.

Allied Motion - New MFH170i Housed Brushless Torque Motor Has Integrated Servo Drive and Optical Encoder

Allied Motion's Megaflux MFH170i series of 170 mm (6.7 in) diameter housed brushless torque motors consists of a high performance brushless DC torque motor, a digital servo drive, and an optical encoder, all integrated into a rugged machined aluminum housing with robust duplex bearings. The MFH0170i series features a 63.5 mm (2.5 in) large-bore through shaft, and is characterized by a very high torque-to-inertia ratio. There are three stack lengths in the series with peak torque ranging from 8.5 up to 16.9 Nm (75 up to 150 lb-in). The standard winding voltage is 48 V. And to ease the hassle of long leadtimes for prototypes, the new MFH170i is now available through our QuickShip program.
