Brushless motor tergo emf constant KE est excultus, quia hic includit contra electromotive vis motor constans ke ke et generantis inductionis motricium, sed non idem est quod KE = EDICTUM Motor , et non est quod KE = E / N = N KE = E / N = / n, 0 in technica requisita motor, the motor rated voltage U, motor rated speed of nN is must be some N is the speed of the motor output shaft, can be measured, but E did not express on the shaft of the motor, cannot express in the input motor power, motor coil is a quantity of the internal potential. In formula, in voltage u est potentia input finem clarum initus, sed idealis non-onus gyrationis celeritas motricium n, 0 in hastili fine motricium non exprimere et mensurae, ut ke est difficile. How the technical conditions of the brushless motor or mechanical characteristic curve of determining and calculating KE counter electromotive force constant of the motor, the design conforms to the KE parameter values of mechanical characteristic curve of the brushless motor is a need to study the topic if the KE, KE = NΦ Effective conductor / 60, then the motor number N and motor flux & Phi; The product of the (Magnetic chain NΦ ）KE to counter electromotive force of the motor constant values, then the mechanical properties of the motor is basically achieve the desired mechanical properties. Observed here are several counter electromotive force of the motor constant KE method, thus the effective number of conductor N of the motor, finally achieve the aim of brushless motor design.
