Closed Loop Control Stepper Motor

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.

Closed loop control stepper motor.

1 8 deg holding torque. 8hs22 0804d e1000 number of phase. 0 054 nm 7 65oz in rated current phase. 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.

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. Normally operates in open loop control for the same ease of use as a stepper motor. The rotor position detection sensor monitors the rotation speed and amount. Closed loop stepper motor.

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. If you have been following my autocrafter build there also an update for that project. By utilizing the high responsiveness of the stepper motor moving a short distance for a short time is possible. The term is open loop vs closed loop watch and discover.

Closed loop capable stepper motors merge the benefits of stepper and servo motor technology. 8 5 ohms 10 inductance. 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 8 a phase resistance.
