About Closed-loop Control Systems
Closed-loop stepper motors, unlike their standard contemporaries, can recover missed steps, are able to accelerate quicker, run faster, maintain torque at higher speeds and run quieter. This is due to the low inductance of the motors and advanced DSP control system when paired with the HSS57 closed-loop stepper motor driver in this bundle.
Built into the closed-loop stepper motor is an encoder that provides position feedback to the stepper motor driver which in turn provides error correction. This error correction is achieved by the driver comparing the commands given from an external source like a micro-controller to the rotation achieved by the motor and any loss of steps is compensated for.
By default, programing the closed-loop motors is not required and can be used right out of the box.
These motors have the NEMA23 footprint and are a drop-in replacement for most CNC systems. Please note that an 8x8mm coupling is required for systems using our Acme Lead Screws and 12mm ball screws.
