CNC stepper motor

What is open loop and close loop positioning system in NC machine?

In simple terms an open loop system will send a command to the stepper motor (and the axis it is connected to) to move a precise distance and the system has no way of knowing if the motor actually moved or if the correct axis moved the desired distance. In an open loop system is is very possible for the CNC machine to “loose” steps if the load on a particular axis exceeds the design load or if a component breaks or is not functioning correctly (example, a drive belt is slipping).

In a closed loop system there are sensors that constantly measure the actual position of the stepper motor or axis. The actual distance moved can then be compared to the distance requested. If the requested distance varies from the actual distance then closed loop system may simply sound an alarm and stop the machine or it may to compensate by sending additional movement commands until the actual distance moved is correct.

A closed loop system is much more expensive and requires a more sophisticated set of software so typically closed loop CNC machines are only found in high end commercial applications.

Cloudray Stepper Motor Series has set the standard for quality, reliability, and durability in stepping motors. The precision of our Torque Power motors is matched only by the dependability of their performance. All Torque Power motors are bi-directional and totally enclosed with permanently lubricated ball bearings for long-lasting, smooth operation.

Cloudray stepper motor series are widely used in medical instruments, robotics, 3D printers, extruders, laser cutters, engraving machine, textile equipment, packaging machinery, CNC machines, etc. nema 23 bipolar stepper motor for 3D printer and CNC
 
High Torque, High Precision and Long life is Cloudray's core advantages
Low vibration,Low heating, No loss of step
Fast Response,Better Acceleration Performance
Thanks to a robust design they can be selected for the harshest environments. Precise, open-loop, speed and position control can be achieved with the application of full step, half step, or microstepping electronics.

Higher Resolution,Avoidance of Resonance Regions
Stepping angle is adjustable( rang in 18°±5%), 0.9 °stepper motor's stepping angle is smaller, fineness is higher and positioning is more accurate.Avoiding vibration,runs more smoothly and gets lower noise.
