question
For axial magnetizing cylinder, what is the maximum OD limit that can be realized by our equipment? In addition, what are the size limits of square and cylindrical blanks?
Answer
At present, our company produce axial magnetizing cylinder with an OD of 49 mm. We can produce D100-200 mm cylinders with lateral pressure machine. The maximum size of square blank is the same as above. The maximum size of cylinder can be produced is D80 * 40 mm. It is not recommended to produce too large axial magnetized products, otherwise the flux consistency of the product will be affected which will lead to motor vibration increasing and heating after installing motor.
question
Under normal slow-speed of revolution, the installation test parameters of products with a servo motor are abnormal, and the continuous torque output at rpm 4500 is insufficient. Whether it can be determined as Br insufficient?
Answer
The Br cannot be determined as insufficient for the poor torque, it can be caused by insufficient driver current.
question
How to confirm whether there is core saturation?
Answer
Whether the core is saturated or not can be confirmed by simulation calculation.
question
For the same specification of magnetic steel, what is the approximate percentage difference in quotation by coercive force in median, high and low levels?
Answer
Take grade H for example. The coercive force can be classified into median, high and low levels, namely 17, 18 and 19KOe with a price difference of 7-20%. The difference between different specifications is large, depending on specific specification.
