1Nm 2Nm 3Nm Nema 23 57mm Bipolar Stepper Motor For Valves And Pumps
1Nm 2Nm 3Nm Nema23 57mm dc cnc Bipolar Stepper Motor for valves and pumps
1) Product Description and images
The output torque of the stepping motor decreases with the rise of the pulse frequency. The higher the starting frequency, the smaller the starting torque, and the worse the ability to drive the load. It will cause out of step when starting and overshoot when stopping. In order to make the stepping motor quickly reach the required speed without losing step or overshoot, the key is to make the torque required by the acceleration fully utilize the torque provided by the stepping motor at various operating frequencies, but not exceed this torque.
Therefore, the operation of the stepping motor generally goes through three stages of acceleration, uniform speed and deceleration. It is required that the acceleration and deceleration process time be as short as possible and the constant speed time be as long as possible. Especially in the work requiring rapid response, the running time of the stepping motor from the starting point to the end point is required to be the shortest, which requires the shortest acceleration and deceleration process, and the highest speed at constant speed.
