Frequently asked questions about the selection and application of automatic magnetizer for motors

In the production of electric motors, the application of automatic magnetizer is becoming more and more widespread, and the number of questions that enterprises have when purchasing and using them has also increased. First of all, what is the core advantage of automatic magnetizer compared to manual magnetizer? The answer is obvious: efficiency increase 3-5 times, a single device can achieve 500-1000 pieces of magnetic insertion operations per hour; insertion of high precision, error ≤ ± 0.02mm, to ensure the consistency of the magnet steel arrangement, thereby enhancing the performance of the motor; at the same time can also reduce labor costs and operational risks, to avoid damage to the magnets and injuries to personnel, and automated production lines and seamless, to achieve continuous production.

Many companies are concerned about whether different types of magnets (e.g. NdFeB, Ferrite) need special automatic magnet insertion machines. In fact, the mainstream motor automatic magnetizer supports multiple types of magnets, by replacing the special fixture and adjusting the magnetizing force, it can meet the magnetizing needs of different materials and shapes of magnets (square, curved). However, for oversized or special shaped magnets, it is necessary to customize special models to ensure that the magnets do not crumble or shift during the insertion process.

Magnetic insertion accuracy is one of the core pain points that enterprises are concerned about, how to ensure the accuracy of the motor automatic insertion of magnetic insertion machine? This needs to be controlled from three aspects: equipment configuration, the choice of servo motor drive, high-precision guide rails and visual positioning system; fixture design, customized according to the size of the magnet and motor housing to ensure accurate positioning; daily use, regular testing of the position of the insertion of the magnetic head, adjust the pressure parameters, to avoid mechanical wear and tear affecting the accuracy. High-quality equipment can maintain the stability of insertion accuracy for a long time, and the error control is at the leading level of the industry.

For mass production companies, can the capacity of an automatic motor magnetizer match the demand? The answer is yes. Manufacturers can provide single-station, double-station or multi-station automatic magnetizers according to the production line capacity requirements, and the capacity of a single double-station machine can reach more than 1,200 pieces per hour. At the same time, the machine supports linkage with loading, testing and unloading machines to form an automated magnetizing production line, which meets the demand for continuous operation in the production of large-volume motors.

There are also questions about the maintenance costs, in fact, the maintenance costs of automatic magnetic insertion machine is relatively low, the core maintenance points include: regular cleaning of the magnetic insertion head and fixture, to avoid the accumulation of magnetic powder; lubrication of the transmission components (rails, gears), to extend the life of the machinery; test the pressure of the pneumatic system and the circuit connection to ensure that the operation of the stable; replacement of wearing parts (such as fixture gaskets) when the use of the original parts, to avoid affecting the accuracy.
