Closed Loop Control Of Stepper Motor

When an overload condition is detected it will instantaneously regain control using the closed loop mode.

Closed loop control of stepper motor. 8hs22 0804d e1000 number of phase. 1 8 deg holding torque. Closed loop stepper systems supply the motor with just enough current to control the load and this results in much less audible noise than open loop setups. 0 8 a phase resistance.

Nema 8 closed loop stepper motor 0 054 nm 7 65oz in encoder 1000cpr sku. These stepper motors use our alphastep closed loop technology to maintain positioning operation even during abrupt load fluctuations and accelerations without hunting or gain tuning. Stepper motor systems using closed loop control represent a small percentage of stepper motor applications but if loss of position could be catastrophic to the application yet the system requires high torque at low speed relatively simple architecture and relatively low cost compared to a true servo motor system a closed loop stepper might be the most appropriate solution. 0 054 nm 7 65oz in rated current phase.

To produce the test results shown in the plot of acoustic noise accompanying this article the acoustic noise of each system is measured in a soundproof chamber. They run more smoothly and have a lower resonance than stepper motors provide position feedback and control feature short settling times and exhibit no step loss at all. Closed loop capable stepper motors merge the benefits of stepper and servo motor technology. Electrical specification manufacturer part number.
