Transform Medical Respiratory Care
Motor control failures in respiratory devices can mean the difference between life and death. In the respiratory industry, motor control of fans and blowers remains a dominant source of technical issues, causing significant project delays and reliability concerns. These critical applications demand motor control products that offer low power consumption, precise high- and low-speed control and unwavering reliability—whether deployed in hospital ventilators or home medical devices.
Our Brushless DC (BLDC) motor control, graphics display, power management and signal processing solutions address these challenges head-on, delivering the precision and reliability required for critical respiratory equipment, from hospital-grade ventilators to portable home devices.
Experience sophisticated sensorless Field-Oriented Control (FOC) technology that enables rapid motor response in milliseconds for patient comfort and safety.
Demo Overview
Our Respiratory Equipment Demo provides core functions and components of the BLDC motor drive solution and closed-loop control mechanisms for CPAP and ventilator applications.
The demo showcases different modes to put air/gas into a patient based on the following fundamental principles and parameters:
- Pressure: Inflate user to a certain pressure
- Volume: Put a certain amount of volume into user
- Respiratory Rate: Number of breaths per minute
- Flow Rate: Motor RPM speed
- Time: Inhalation and exhalation time length
- Ramp Rate: Get the pressure/volume slowly or quickly
Three Powerful Demo Modes
Mode 1: Open-Loop Control
Demonstrates basic motor control with user-adjustable parameters and is great for CPAP settings
Mode 2: Pressure Control
Closed-loop pressure regulation for ventilator applications, maintaining precise airway pressure
Mode 3: Volume Control
Closed-loop volume delivery for anesthesia machines, which enables accurate tidal volumes
