World First: robotic system for eye surgeries

Dutch company Preceyes developed a world first robotic system for retina disorders, using haptic feedback and maxon DC motors.

Detached retina surgery requires precision to an nth degree where the stability of human hands are no match compared to robotic systems. This is why Dutch company, Preceyes, developed a completely new robotic system for eye surgery. Especially designed for the treatment of retina disorders, the robotic device improves precision up to 20 times more than a Surgeons hand, making operations once deemed impossible due to lack of precision now being successfully performed.

Surgeons operate via a joystick while looking through a microscope. The joystick controls a robotic arm, controlled by maxon DC motors, assisting surgery in millimeter increments. A haptic feedback function allows the surgeon to see and feel their actions and the robotic system supports quick retooling. This is an important factor because it reduces operation time bringing a multitude of benefits to the patient.

DC motors in blood analysis machines

High-tech machines analyse human blood samples and detect coagulation disorders. Maxon motor France supplies the DC drives as well as builds entire conveyor modules especially for a customer.

Analysis devices in laboratories and hospitals run 24/7, autonomously pipetting samples to deliver quick results. Such industrial automation equipment must work with high accuracy and reliability. This in turn places high demands on all components of the machines.

Stago is a French company that specialises in analysis instruments for haemostasis diagnostics (for testing blood clotting). Maxon DC motors are found in Stago’s StarMax machine. A fully automated analysis system, the StarMax is equipped with a three-axes robot with space for 215 samples and 1,000 test containers. Working autonomously the machine checks results, compares them and monitors the processes.

There are several varieties of maxon’s brushed A-max DC motor combined with planetary gearheads, that are used for the movements of the rack. With varying diameters between 16 and 26mm, these DC motors were selected for being highly dynamic and easy to control. The DC motors have an ironless rotor and are manufactured autonomously giving them an attractive price-performance ratio.

Mechatronic drive system in elevator doors

Maxon brushless DC motors and encoders drive lift doors open and closed.

Schindler is a well-known manufacturer of elevators and lifts, moving more than one billion people every day. When we take the lift, we press the button, the cab arrives, we enter and disembark at the desired floor. What is a simple event has alot of technology in the undertaking – in the elevator shaft, motor chamber, control box and in the lift compartment itself.

A motor installed in the cab opens and closes both the doors of the cab and the doors at each particular floor. The requirements of the motor are very specific: small yet powerful, reliable, energy-saving and intelligent. Maxon developed two Door Drives alongside Schindler, using a brushless DC motor with a diameter of 90 millimeters, a MILE encoder combined with the motor and a customised EPOS2 positioning controller. With two power levels, the more powerful version uses a belt drive and is able to move doors weighing up to 400 kilograms. The smaller and latest version is more compact and moves doors weighing up to 120 kilograms.

Encased in a housing, the Door Drive can be mounted directly onto the lift cab. And this is where its real work starts. The ability to adapt to the many different types of elevators, with differently sized cabs, different materials and, depending on the country, different safety standards. After a calibration procedure, the controller of the Door Drive detects the size and weight of the doors, autonomously calculates the optimal parameters corrects them if necessary and drives the doors open and closed.
