How to choose propulsion system? CNC routers , CNC engravers , CNC machines , 5 axis CNC machines , Infotec Group
For construction in the CNC Machinery Industry companies use servo motors or stepping motors. From type of solution depends to a large extent, machine
parameters such as:
- Positioning accuracy
- Speed of movement working
- Accelerate the movements
Devices based on servo motors exhibit a better parameters of work,
because it applies everywhere where there is a high priority for
quality and precision of the implementation of components - ranging
thousandths of a millimeter. Stepping motors due to the simpler
construction and much lower price are used for less demanding
applications.
A stepper motor is a brush less, synchronous electric motor
that can divide a full rotation into a large number of steps. The
motor's position can be controlled precisely, without any feedback
mechanism . Stepper motors are similar to switched reluctance motors, which are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.
A servomechanism
, or servo
is an automatic device which uses error-sensing feedback
to correct the performance of a mechanism. The term correctly applies
only to systems where the feedback or error-correction signals help
control mechanical position or other parameters.
