Maxon Examines Dynamics in Robotic Drives

Maxon offers a new frameless BLDC motor with matching encoder that really comes into its own in dynamic applications. With the EC frameless DT50, maxon presents a new product family developed specifically for dynamic movements. The brushless motor with its frameless concept can be easily integrated into a wide range of applications by design engineers. It really comes into its own here in applications where speeds can change in an instant,such as in collaborative robots or exoskeletons. When installed, the EC frameless DT50 effortlessly reaches a nominal torque of over 500 mNm at a nominal speed of 4,000 rpm. This is despite a stator with an outside diameter of only 50 mm. At the same time, the new winding technology enables a very short motor length with a very large hollow shaft of 28 mm.

The TSX-MAG encoder completes the EC frameless DT50. It is a new through-shaft encoder that is not installed directly on the motor axis (off-axis installation). This gives engineers great freedom when it comes to design. The encoder can generate both Hall signals and incremental signals, which allows field-oriented commutation of the motor. More versions of the TSX-MAG and additional drive combinations will soon follow.
