Check out the latest publication from the maxon academy, Motion Control for Newbies, a practical introduction to motion control. 132 pages.
The basic approach of this textbook, like many, is a practical and experimental one; however, it is reversed from most. Instead of first explaining the theory of motion control and then applying it to specific examples, here we will start with hands-on experimenting on a real maxon EPOS2 P positioning control system by means of the EPOS Studio ...Categories: Technical Support - Posted: June 01, 2014
Whether traversing over the sands of Mars, or walking up a stone path, this robot was designed to move easily and quickly, to jump, and even to flip over.
The biologically inspired robots being designed at the University of Pennsylvania aim to provide new levels of mobility and durability, while providing the capability for rapid behavior development. The X-RHex (Robot Hexapod) is the latest version of the highly mobile RHex platform. X-RHex was designed for greater strength, longer runtime, and more mobility than previous versions, plus it is the first RHex to be built to carry a modular payload architecture to support a wide variety of research requirements.
The six legged robot is modeled after insects where three legs are always touching the ground at the same time. As a running robot...Categories: Whitepapers - Posted: March 30, 2014

Coating and lamination applications demand precise speed regulation in order to avoid velocity ripple that causes uneven coating and undesirable horizontal bars across the substrate. The key to achieving the most uniform coating is minimizing the variations in velocity as well as in metering of the coating material. Coating and laminating applications are characterized by compliance caused by the elasticity of the web, which in turn produces variations in torque requirements. Web handling machines face the challenge of handling these loads while avoiding velocity ripple that can cause uneven coating and unsightly horizontal bars across the substrate. As an example, consider film coating, where depositing a dark film onto the substrate material at varying velocity would result in a series of dark and ...Categories: Technical Support - Posted: December 01, 2013
Answer: Some slight differences in their magnetic design.
There are several factors that define the type of motion or motor that is best for an application. Directly driving a shaft is not new technology. Moving slow, smooth and accurate while positioning in fine increments takes the right combination of technology. The selection of a motor, encoder, bearing system, and motor controller all contribute to the end result.
Motors that are designed for direct... - Posted: September 09, 2013

Often overlooked when sizing DC motors is the Speed-Torque Gradient.
The Speed-Torque Gradeint is defined as Δn / ΔM [rpm/mNm] .
The speed / torque gradient is an indicator of a motor’s performance. The smaller the value, the more powerful the motor and consequently the less motor speed varies with load variations. It is based on the quotient of ideal no-load speed and ideal stall torque.
The speed torque-gradient can be considered a measure of the motor strength, which is defined by motor type and size and not the winding selected. Basically it’s how much speed drop the motor will have for each 1mNm of torque applied.
In the figure below, enhancing the load torque leads to a linear reduction of the speed. Thus it becomes clear what the meaning of Δn/ΔM is: It’s the gradient of the speed-torque line.

The new issue of “driven”, the maxon motor magazine, brings stories and applications from the field of medical technology to your tablet, interactive and easy to understand. This issue is all about implants and prosthetics, ranging from a state-of-the-art motorized prosthetic hand to an implanted medication pump. The tablet magazine is available for Apple iOS and Google Android.
In the new issue 1//2013 of “driven”, implants and prosthetics take center stage. Learn about the fascinating possibilities of modern prosthetics and how maxon products are used in artificial limbs. For example, did you know that the gripping movement and gripping force of modern hand prostheses are... - Posted: March 30, 2013
The choice between a servo and stepper motor is an important decision in any system design. In general, the higher the performance requirement (high precision, variable load, high duty cycle, high torque vs. speed) the more likely a servo will be the choice. Where purchase cost is critical, performance is not crucial, and simple set-up is needed, a stepper solution is a cost-effective option.
The following chart compares the performance of brush/brushless servo and stepper motors:
With stepper motors, closing the position loop via an encoder is not an effective means of providing increased precision. Whereas the encoder will provide position verification, the step...
