This statement has a certain degree of one sidedness, but it does have some truth. The larger the mass range of the automatic positioning dynamic balancing machine, the larger the measurable rotor mass. However, the larger the mass range, the more specifications of the measured rotor. If the measured rotor mass is too small, it will be out of alignment with the power system, which will not only increase power costs but also affect the service life of the power system. Therefore, when choosing, you should choose the mass range of the dynamic balancing machine according to your needs, rather than blindly pursuing a large mass range.
