Closed Loop Control Of Stepper Motor

Closed loop stepper motor.

Closed loop control of 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. 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. Electrical specification manufacturer part number. 0 8 a phase resistance.

Nema 8 closed loop stepper motor 0 054 nm 7 65oz in encoder 1000cpr sku. The rotor position detection sensor monitors the rotation speed and amount. When an overload condition is detected it will instantaneously regain control using the closed loop mode. 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. 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. 1 8 deg holding torque. 0 054 nm 7 65oz in rated current phase.
