solutions allow designers to simplify the system and reduce the need
for complex software certification, in turn speeding up the development
process and reducing risks in medical applications.
Additionally, size and power efficiency are major considerations in
medical devices, especially battery-powered systems and wearables.
Motors in these applications must be compact yet efficient, making
integration with control electronics critical to maintaining reliability in
space-constrained designs. The rise of smart motor control systems,
in which the motor and control electronics are integrated into a single
package, simplifies device design and reduces the risk of component
failure. Sensitive substances like blood or insulin need to be handled
carefully to avoid spilling or flocculation. Optimized motion profiles and
algorithms for efficient motor control ensure reliable operation for large
lab analyzers as well as highly miniaturized wearable patch pumps.
Meanwhile, the automotive industry has been reinventing itself with a
transition toward EVs and autonomous driving technologies. For example,
motor control systems in EVs manage everything from the main drivetrain
motors to auxiliary systems like power steering and electric braking.
These systems require high power, efficiency, reliability, and safety.
Here, efficient motor control is necessary for maximizing battery life and
extending vehicle range, both of which directly impact overall vehicle
performance and consumer adoption.
Size matters in medical
devices and wearables.
You need motors that
are compact, efficient,
and reliable, especially
in battery-powered
devices for which
power consumption is a
major concern."
