Where high precision is essential and space is tight, BLDC flat motors from Nanotec, headquartered in Feldkirchen near Munich\/Germany, are the solution of choice. The 16-pin external rotor motors of the DF45 series have a standard diameter of 45 mm and a length of 27 mm. New to the product range are the sizes S and M with external lengths of 18 mm and 21.6 mm respectively. The rated power is 30 W for a motor of size S, and 50 W and 65 W in the case of sizes M and L.\rEach model comes either with an integrated connector or connecting wires. A Flex-PCB is also available on request.\rDF45 series motors have their permanent magnets located on the rotor housing revolving around the internal stator with the windings. While these motors generate the same power output as internal rotor motors, they have lower torque ripple due to the rotor's higher inertia. They also have a shorter design.\r The new motors combine low weight with high power density, are highly cost-effective and are used in a wide range of applications.
