Motion Control Trends that Will Benefit Medical and Laboratory Applications

The motion control technology is also used in medical and laboratory equipment applications, so what comes next is to witness where the motion control electronics are small, and the controllers are fast.

Fremont, CA: The application of motion control involving medical and laboratory equipment includes automated devices that is used in surgery, for treatment of the patient, patient imaging, and a variety of machines that operate in the lab, such as blood analyzers, DNA sequencers, chemical, biological assayers, and many more. There are rapid and radical changes in the cost of computing power and amplifier electronics, so much so that, in the era of motion control technology, we have arrived at a stage that can be known as the post miniaturization, post specification era. But this indicates that the electronics have gotten small and are capable of driving high currents that the motion control electronics seldom limit the controller package size. Comparatively, the size is generally limited by connectors and the practical limitations of servicing controllers once installed in the machine.

The traditional standby quadrature encoder has been joined by numerous new position sensing technology and data transmission formats, providing medical machine manufacturers with original package and controller options. When it comes to positioning motion control applications, one feedback device, the incremental optical encoder with quadrature output, has been the king of the hill for quite some time now. With its pocket-friendly and good resolution, this encoder leads to unit volume in today's motion control marketplace.

Getting Smarter and Better

Sometimes, to get the most out of the motor means more information needs to be fed, and the advanced control and torque feedforward schemes are delivering smoother and more efficient plus quieter motion. Many motion applications need smooth action and high accuracy during the task and at the end. The most obvious source of forces needed in the motor is the motor axis' load itself. The load has a mass that reflects inertial forces to the servo loop, and to an extent where the motor or downstream mechanical connections have friction and compliance, these forces also reflect the motor and affect servo tracking.

In the coming days, it is expected that megatrends continue to come up so machine designers can expect further developments in sensors, data collection, motor drive techniques, and analytics that will allow them to build machines that perform better, are more reliable, and cost less.
