Medical diagnostics and therapy

Medical diagnostic and therapy systems often include numerous sensors along with actuators and pumps. From a simple temperature sensor and ultrasonic actuator all the way up to multiple sensors driving pumps for blood, insulin, adrenalin or oxygen. This can be achieved through simple cost-effective stepper or full 3-phase motors. Importantly, whether static mains powered or battery-powered portable devices, they all have to perform to exacting standards.
