How to change a three-phase motor to a single-phase motor?
The wiring method of changing 380V three-phase motor to 220V single-phase motor
Wiring method
Calculation of connected capacitor size and withstａnd voltage
The calculation of the capacitor size is determined in this way, when the motor winding is star connection, the capacity of the capacitor used is C=(800~1600)XI/U. Here I is the rated current value of the three-phase motor, and U is the voltage on the motor windings, generally 220V. For example, for a motor with a rated power of 1KW, the winding current should be 2.5A. If it is changed to single-phase operation, the single-phase voltage should be 220V, then the connected capacitor should be: C=(800~1600)X2.5/ 220=9.1μF~18.2μF, so we can choose a 12μF capacitor.
Estimation of withstａnd voltage
For the connected capacitor, its withstａnd voltage value can be obtained by an empirical formula: UC=1.6U, so the voltage value of the above-mentioned distribution is UC=1.6X220=352V. According to the principle of choosing large and not small, the withstａnd voltage value of the capacitor can be selected as 400V.
