AI Technical Summary
Traditional manufacturing processes result in uneven magnetic field distribution in electromagnets. Existing methods, such as precision machining and screening and elimination, are costly and inefficient, and it is difficult to guarantee the consistency of multiple electromagnets.
By connecting a resistor in parallel to the electromagnet body and adjusting the resistance using an automatic adjustment device, the current passing through the electromagnet body is changed to achieve a consistent magnetic field strength. An automatic adjustment device driven by an adjustable resistor and a servo motor is used.
It reduces manufacturing difficulty and cost, improves the consistency of the electromagnet's magnetic field, avoids resource waste, and increases production efficiency.
