maxon brushless DC motors with encoder in a device for rehabilitation patients.

A maxon brushless DC motor and encoder are the driving force behind a medical device providing therapy for patients who are in need of muscular rehabilitation.

Two Swiss Robotic engineers developed a training device for patients undergoing rehabilitation, eg recovering from strokes or those with neuro-muscular or orthopedic conditions. The Allegro is essentially a leg press machine, controlled by a maxon brushless DC motor that activates a safety stop – the stand-out feature of the Allegro that certifies it as a medical device. By pressing or pulling in their legs, the patient manouveres a moving object to stay as close as possible to a line on the monitor. The computer then adjusts the level of resistance forcing the patient to exert more or less effort. The stop automatically adjusts, preventing the machine from going past a certain angle protecting the user especially those who have limited mobility.

100% reliability is a critical factor of the DC motor drives. “With a maxon motor, we can be certain that this requirement is being fulfilled” said Max Lungarella, co-founder of the company that makes the Allegro, Dynamic Devices AG.

Another feature of the Allegro is a maxon flat brushless motor with an outside rotor that automatically adjusts the seat position. This was achieved by combining the brushless DC motor with a planetary drive and ESCON 50/5 controller. The maxon brushless motors and controllers are a key component of the rehabilitation machine that simultaneously trains both mind and body.
