The iron-wound motors will be available with diameters of 22 mm, 32 mm and 42 mm, each in a short version and a long version. The ratio of torque to weight and size is second to none and is perfect for UAV (unmanned aerial vehicle) and robotics applications. These external-rotor motors can be configured online and are optimised for maximum performance thanks to the special winding tech as well as segmented magnets. Another innovation in the area of BLDC motors is maxon's ECX flat product family. Maxon say more versions of the TSX-MAG and additional drive combinations will follow soon. The encoder can generate both Hall signals and incremental signals, which allows field-oriented commutation of the motor. This gives engineers great freedom when it comes to design. It is a new through-shaft encoder that is not installed directly on the motor axis (off-axis installation).

The TSX-MAG encoder completes the EC frameless DT50. At the same time, the new winding technology enables a very short motor length with a very large hollow shaft of 28 mm. This is despite a stator outside diameter of only 50 mm. When installed, the EC frameless DT50 effortlessly reaches a nominal torque of over 500 mNm at a nominal speed of 4,000 rpm. It is designed to come into its own in applications where speeds can change in an instant, in collaborative robots or exoskeletons, for example.

The brushless motor with its frameless concept can be easily integrated into a wide range of applications by design engineers. The DT50 is the precursor of a new product family developed specifically for dynamic movements. With the EC frameless DT, maxon is offering a salient solution that it says really packs a punch. Innovative motor concepts meet growing market requirements for dynamic response, compactness and power density. © maxon This heralds the arrival on the market of several solutions for design engineers grappling with tight spaces.
