Why do single-phase motors use capacitors, but three-phase motors do not need capacitors?Before that, let's first understand the characteristics of some single-phase motors and three-phase motors. Single-phase motor: There are two coils in a single-phase motor, the main coil and the auxiliary coil. When a single-phase sinusoidal current passes through the main coil, the main coil will generate an alternati...2021.04.26 06:42brushless motor
How to deal with the gear deviation of hard tooth surface reducerHard tooth surface reducer gear pitch cumulative deviation: the algebraic difference between the actual arc length and the theoretical arc length of any K tooth pitch. In theory, it is equal to the algebraic sum of the individual pitch deviations of these K tooth pitches. The tooth pitch number K is given by design.Har...2021.04.19 05:53brushless motor
