Planetary gearmotors for solar photovoltaic tracking applications

When it comes to specifying electric motors for solar photovoltaic tracking applications, environmental protection is a prime consideration due to their exposure to the elements. Motor designs for solar power applications must stand up to extremes in temperature (both absolute and over a broad range), humidity and highly corrosive salt sprays, wind loads, and abrasive airborne particulate matter. Because they are exposed to the elements, motors should be designed to IP65 (protected against dust and water jet spray) or IP67 (protected against dust and effects of immersion in water to a depth between 15 cm and 1 m).

Both the motors and the gearheads attached to them must be optimized for the low speeds and high torque that characterize solar tracking. Gearing considerations include such elements as engineered lubrication, low-friction gear design, and special sealed ball bearing designs, along with appropriate treatment of output shafts and housings. As a complement to this safety system, the gear motor includes an electrical brake that absorbs the effect of the wind on the mobile elements of the tracker, thus avoiding damage and helping to extend the useful life of the machine and its main elements.

Permanent magnet brush dc motors (PMDC) are relatively efficient, easily controllable and, if properly built, can last a long time , despite the brush or commutator wear that is inherent in their design. They also exhibit a wide speed range that is advantageous in stowing situations.

ApplicationApplicationBreath Ventilator Motor

Global estimates suggest that around 5% of COVID-19 patients will require intensive care involving a ventilator. That might seem like a small figure, but physicians and doctors around the world have been warning of health care systems overrun with patients. Ventilator shortages in the worst-hit nations, such as Italy, have already forced health care workers to choose who gets to live.

As the coronavirus continues its grim march across the global battlefield, nations are quickly finding out they don't have enough missiles. And so the pandemic is inspiring a wave of innovation and rapid development of new and improved ventilation devices that could be key to keeping the coronavirus in check until a vaccine or effective, standardized treatment comes along.

The ventilator has become a symbol of both the hopes and fears of health care workers across the globe as they struggle to get the pandemic under control. Indefatigable in its mission to keep lungs filling and emptying, the device has been a constant, silent force inside hospitals for over 60 years. Now it's being called on for its toughest mission yet.

With the increasing need for patients to be mobile, both in the hospital and in a home setting, the need for highly capable, efficient and portable ventilators has increased.

Quiet, reliable and efficient, Twirl Motor’s ventilator medical motors can effectively power ventilator blowers on battery at night, during inter-hospital transport, in emergency vehicles or comfortably in a stationary home or hospital setting.
