There was a time when a hand amputee would have been asked to use a hook prosthesis that had limited functions and carried a significant amount of social stigma. Today, designers are looking to build prosthetics that are not only functionally efficient, but also durable, comfortable, lightweight and aesthetically pleasing. Here, Chetan Kale, R&D Engineer at Portescap has dicussed how standard motion solutions can meet all of these requiremen...

Encoders provide feedback for accurate motor control relating to speed and positioning. Here Chris Schaefer, Applications Engineer at Portescap, has looked at the technologies involved and explained how to choose the encoder for your application.

With designers of medical analysers under pressure to develop miniature motor technology that are smaller, faster and even more accurate, the selection of the most appropriate motor to drive the different axes becomes a key consideration.

The new Ultra EC range of Brushless motors from Portescap has been expanded with the 22ECP35 two pole brushless DC motor. As part of the Ultra EC platform of brushless slotless mini motion solutions, these cost-optimised motors offer 30% more continuous torque and 100% more power over similar comparative motors without compromising the smooth operation and long life required from a brushless DC motor.

  The new 35DBM high power stepper can stack linear actuator has been introduced by Portescap as a 35mm linear stepper motor, which offers an enhanced design suitable for applications demanding high linear force.

Portescap introduces the M Sense B Encoder, designed specifically for applications that require high accuracy in a compact design. The M Sense B is the first in its class to offer accuracy in the range of 1-1.5°, covering a resolution band of up to 1,024 lines with an integrated line driver resulting in accurate positioning and speed control.
