DescriptionThe current control feature optimizes drive performance, balances and motor torque, optimizes energy efficiency, delivers smooth and noise-free, and reduces energy consumption. Allows the motor to operate near its load limit and speeds limit, achieving a dynamic range of greater without any out of step.Features- Color: Assorted color. - Material: Plastic, metal. - Size: 2.00X1.50X1.00cm/0.79X0.59X0.39 inch. - Even if the wrist frequency system is limited, it may still be perfect to achieve sinusoidal control. - Even in the pulse rate, a limited system can still be perfect to achieve sinusoidal control. - These components are also designed to be compatible with 3D printer electronics, eliminating the need for costly redesign. - Both components have pulse / direction input, which can be completely independent operation. - It is manufactured with professional technology to ensure the of the product and can work for a long time.
