Multiple motor windings are connected in series to an electric drying circuit

If there are several motors with the same or similar capacity, you can connect the windings in series as shown in the figure, then use a wooden block to secure the rotor so that it cannot rotate, and then close the knife switch to energize and heat. To observe the current value of each phase through an ammeter, it should be 70% to 80% of the rated current value of the smallest capacity motor. If the current is too large, a few more units can be connected in series; if it is too small, reduce the number of units connected in series. Continuously power on for 7 to 8 hours to meet drying requirements.
