Since it was initially reported on 31 December 2019, the illness known as coronavirus 2019 (COVID-19) has spread rapidly, putting the world on edge. As of 12 June, close to 7.3 million confirmed cases and over 413,400 deaths have been reported globally since the outbreak began in more than 200 countries, territories and areas, with new cases and countries reporting daily. As always, better health is central to human happiness and well-being. Never before has medical technology played a greater role in public health than during the COVID-19 pandemic. DC motors are often applied to advanced medical technology, giving medical applications greater accuracy and professional control. ZHAOWEI develops a wide variety of medical gearboxes for demanding medical equipment, including those used in surgical, clinical and laboratory settings.  

ZHAOWEI DC Motors Empower Medical Equipment

  • Medical Massage– Optimized Control

A soothing massage after a tiring day at work is an effective way to wind down. Massage therapy helps relax knotted muscles, eliminate chronic aches and pains, and improve circulation. It can also help release muscle tension and improve the mobility of the joints. Medical massages occupies a large part in medical applications, especially eye, muscle massage.

Massaging the eye area can increase oxygen to the eyes and brain. Using kneading or rolling compression, sometimes along with heat, the devices can stimulate blood flow and reduce eye fatigue. The multi-stage gear transmission mechanism for eye massager launched by ZHAOWEI enables these functions. The dedicated planetary gear design greatly helps to reduce noise when the eye massager is operating in different stages (stage 2, stage 3, and stage 4) of gear transmission, providing more choices for the frequency and intensity of the eye massager in accordance with design requirements. Electric scalp massagers work this way as well. ZHAOWEI has optimized the gearbox structure design to achieve high torque, low noise and a long service life.    

  • Ventilator– Intelligent Adjustment

According to Global Ventilator Market: Regulatory Landscape, Analysis and Forecast, 2021-2030, the global ventilator market was valued at $1,142.0 million in 2019 and has witnessed a growth surge of up to 172% in 2020 due to the rise in demand during the coronavirus outbreak. Moreover, the market is anticipated to normalize from 2022 and grow consistently with a CAGR of 15.13% during the forecast period of 2021-2030. These prospects are promising. Additionally, according to WHO, one in six COVID-19 patients becomes seriously ill and has breathing difficulties. For this reason, ventilators - mechanical breathing devices - are crucial in the fight to save patients whose lungs are assailed by the virus.

ZHAOWEI intake valve motors can allow ventilators to intelligently adjust the intake volume. The design principle of the motors allows the regulating valve of the medical ventilators to achieve intelligent adjustment of the size of the oxygen jet hole under the combination of a helical worm and the pressure of intake valve. Choose the corresponding orifice-plate diameter under different output flow to achieve an impressive absorption and back-pressure ability. Compared with existing technology, ventilators with intelligent adjustment make lower oxygen concentration and higher stability possible under the same back pressure and different flow.  

  • Cochlear Implant- Light-duty Application

An artificial cochlea or cochlear implant is an electronic device that transmits a sense of sound to people with severe hearing loss. The implant consists of an external portion that sits behind the ear and a second portion that is surgically placed under the skin. The Global Cochlear Implants Market - Industry Trends and Forecast to 2027 shows that the global cochlear implant market is expected to rise to an estimated value of USD 10.54 billion by 2026, registering a substantial CAGR in the forecast period of 2019-2026. To meet the requirements of both quantity and quality, related industries will adopt components like medical motors and gears to upgrade cochlear implants. Related solutions can be provided by ZHAOWEI, which combines the plastic gearbox with the stepper motor (or a customized type). The plastic gearbox aims to reduce weight and increase efficiency, contributing in no burden on the ears. It can absorb shock and vibration as a result of elastic compliance and stays quiet when running. The stepper motor is well-suited for light-duty applications like this one because it combines high torque and a compact design, which in turn gives it an expected response, responsive acceleration and easy position control.      


Health will constantly remain a popular topic due to its significant contributions to social progress. Customizable and precise drive systems for various medical applications by are available from ZHAOWEI to reduce assembly costs while also maintaining stable performance. No matter what next challenge the medical industry is confronted with, ZHAOWEI will strive to meet and exceed customers’ needs for miniature gear motors to be used with medical equipment.
