The 24V DC brushless reduction motor is a miniature deceleration micro drive motor, mainly composed of a DC brushless motor and a reduction gearbox assembly. Characteristics of DC brushless motor: The characteristic of DC brushless motor is that the waveform of the induced voltage between different 2-phases of the armature coil is roughly trapezoidal. The induced voltage waveform is formed by replacing the odd number of tone components on the first fundamental wave, except for the first component that is a multiple of 3. The induced voltage waveform is formed by the first fundamental wave, important 5th and 7th components. The total content X (=(as+a7)/a) of the voltage peaks as and a relative to the 5th and 7th components of the voltage peak a1 of the 1st fundamental wave Within the range of 0.01<X<0.1. The waveform of the induced voltage between two different phases in the armature coil is roughly trapezoidal.
