The demand for ventilators is rapidly increasing due to the New Crown epidemic. According to the World Health Organization, 13% of critically ill and 6% of critically ill patients with New Coronary Pneumonia require timely ventilator treatment. Ventilators need motors with low vibration, low noise, long life and stable wind pressure. RB‘s brushless DC motors have high efficiency bearings and zero-return operation for the fastest response. Reliable, quiet and efficient. The BLDC motors are able to efficiently drive ventilator blowers at night, during transfers, in emergency vehicles or during intercontinental flights on battery power.
