Background technique

In the invention patent "curved knife slotting machine" with the application number of 201310305277.0, a slotting machine is disclosed, which realizes the process of slotting through the uninterrupted back and forth movement of the curved knife. This back and forth motion is driven by the motor. It is realized by forward and reverse rotation, which requires frequent commutation of the motor. Because the current of the motor at the moment of commutation is much greater than the current of its normal operation, the invention has the following defects: ①The current is too large, which causes waste of electric energy; ②The large current at the moment of commutation will impact the power grid, increasing the ③The motor generates too much heat, which is easy to burn out, shortening the life of the motor; ④The motor is prone to jamming when it is reversing with load, and it also impacts the mechanism, shortening the life of the mechanism.
