I can't. You need to use more than 4.5g, a larger energy band. 4g can also be used, but it is useless. Therefore, the 5.5 4g motor of 007 flour bulking machine cannot be used, and it is easy to damage the motor because it cannot move. Moreover, the parameters of the expander are generally greater than 4g, and S is generally 4.5 to 5G. If you use a 4g motor, you can drive it, but the power is not enough. After a long time, the motor will burn out.
