Difference between Spindle Motor and Servo Motor

As far as use, the servo motor is essentially answerable for the feed of the machine apparatus, making the workpiece move to the instrument or the device move to the workpiece, primarily to understand crafted by cutting, with higher necessities for force and control precision; while the spindle motor is mostly liable for driving the axle of the machine device, driving the workpiece or the instrument head to pivot, with higher prerequisites for consistent power trademark result to meet the adequate force yield capacity at various velocities. In this manner, while planning, these two engines will make designated boundary streamlining as per their application necessities separately.

Elements of spindle motor

Adequate result power: CNC machine apparatus spindle load nature is like “steady power”, that is the point at which the machine device axle speed is high, the result force is little; shaft speed is low, the result force is huge, to guarantee that the shaft can have adequate drive power under various working circumstances. That is, the necessities of the shaft drive gadget (axle engine) to have “steady power” attributes of the result bend;

Speed range: to guarantee that the CNC machine instruments for a wide range of devices, handling materials; adjust to a wide range of machining processes, the necessities of the shaft engine have a specific speed range. However, the prerequisites of the shaft than the feed are lower.

Speed precision: the overall necessity of static contrast is under 5%, higher prerequisites for under 1%;

Quick: shaft drive is in some cases utilized in the situating capability, which expects that it likewise has a specific level of velocity.

Features of servo motor

The mechanical qualities of the servo engine necessities: the servo motor is expected to have a little speed drop, in a specific speed reach can keep a consistent force result, and static solidness.

The need to accomplish rapid control reaction: predominantly in the shape handling, particularly the bend of the handling object for high velocity handling, the servo engine speed, and force control reaction time has extremely severe necessities.

The actual engine has an extensive variety of speed guidelines: used to meet the CNC spindle devices adjusted to a wide range of instruments, handling workpiece materials, and can adjust to a wide range of machining processes.

With over-burden force result and steady force yield ability: machine device feed (servo engine) the idea of the mechanical burden is for the most part to defeat the grinding of the table and cutting opposition, so the principal “consistent force” nature, yet additionally to make some short memories force over-burden limit. Like the standard servo engine available, the over-burden limit can arrive at multiple times or much more.

Difference between spindle motor and servo motor

Difference of principle

The spindle motor is an accuracy nonconcurrent engine on the grounds that CNC machine instruments have high necessities for movement control, need to have great powerful qualities, huge speed range and exact position control precision, so it needs a unique servo engine. The rule is equivalent to the overall squirrel confine engine, the greatest distinction between the coordinated servo engine and the nonconcurrent engine is that the design of the rotor is unique. Coordinated engines have staggered posts on the rotor, and hence require relating location components to identify the rotor position. While supplanting these location components additionally should be rearranged.

Distinction of working reach

The servo engine works in the steady force region between the least speed and evaluated speed, while the shaft engine works in the consistent power region between the appraised speed and the most noteworthy speed in light of the fact that to accomplish an enormous speed range, the evaluated speed of the axle engine is by and large exceptionally low.

Contrast being used

The engine is utilized to identify the speed of the speed generator, the Lobby component equally separated on the outline of the engine to identify the overall place of the rotor, while the shaft engine is utilized to distinguish the engine speed with a position encoder, the engine encoder notwithstanding the traditional A, B, and R-stage sine cosine signal, there are two C-stage and D-stage sine cosine sign to distinguish the place of the engine rotor.
