The PYRO motors belong to the new PREMIUM-Line at KONTRONIK. We have developed these motors in cooperation with leading manufacturers of electric heicopters in order to take the performance of electric drives to a new edge.
The indiviually calculated metal sheets are optimized for the magnetic flux of the motor jacket. Optimized ventilation together with a high performance radial fan and an up to 300 degree Celsius heat resisten coil allow high input voltage.
In 3D helicopter flight a motor is heavily used. And it is exactly for this reason that a PYRO is well - equipped.
It's special design and construction make it handle a continuous power of 3,000 W and a maximum of 5,000 Watt for 1 second.
To achieve this a high-quality Neodym material was used for the magnets heat resistible up to 150 °C.
The winding is made of an extremely heat resistant copper, normally used by the aerospace industry.
The rotating can additionally gets a precise balancing. So the thin section bearing is rendered unnecessary.
A continuous power of 3 kW produces a lot of heat even in such an efficient motor as the PYRO. A new designed cooling stream enables the PYRO to release the heat absolutely reliably.
