When removing old wires for motor repair, record the number of turns in each slot, measure the wire diameter, clean the slot opening, line it with insulating paper, secure the wire bundle, lower it into the slot, and seal the opening with a bamboo skewer. This completes the process. For new wires, refer to the stator data to find the wire diameter and number of turns.
If no data is available for the motor, calculate the magnetic flux (Gauss) based on the mass of the silicon steel sheets. Then, calculate V/A/turn based on the stator pole width, length, and slot depth. Multiply this by the voltage to calculate the required number of turns. Calculate the wire diameter based on the slot area. Follow the above method to complete the wire removal process. Pre-dry the wire, then impregnate it with varnish and dry it completely. Finally, determine the motor power based on the allowable current of the wire diameter.
