EC / BLDC Motors
36Pages

280 0.8 EC motors are also called brushless DC motors. Their construction is equivalent to the construction of a three-pha0.7 245 se synchronous motor with permanent magnet rotor. There 0.6 210 are no service life limited parts (except for ball bearings), like 0.5 175 for example the carbon brush for DC motors. However, the 0.4 140 control behavior and characteristic curve of EC motors are 0.3 105 similar to those of a DC motor. By means of the simple and robust design and the low requirements of control electro0.2 70 nics this motor type can be used with a simplified frequency 0.1 35...
