To the extent that utilization, the servo engine is basically responsible for the feed of the machine mechanical assembly, making the workpiece move to the instrument or the gadget move to the workpiece, essentially to grasp created by cutting, with higher necessities for power and control accuracy; while the shaft engine is for the most part obligated for driving the hub of the machine gadget, driving the workpiece or the instrument head to turn, with higher requirements for reliable power brand name result to meet the satisfactory power yield limit at different speeds. As such, while arranging, these two motors will make assigned limit smoothing out according to their application necessities independently.

Components of spindle motor

Satisfactory outcome power: CNC machine contraption axle load nature is like “consistent power”, that is the place where the machine gadget hub speed is high, the outcome force is pretty much nothing; shaft speed is low, the outcome force is immense, to ensure that the shaft can have sufficient drive power under different working conditions. That is, the necessities of the shaft drive contraption (hub motor) to have “consistent power” properties of the outcome twist;
Speed range: to ensure that the CNC machine instruments for many gadgets, taking care of materials; conform to an extensive variety of machining processes, the necessities of the shaft motor have a particular speed range. Nonetheless, the requirements of the shaft than the feed are lower.
Speed accuracy: the general need of static differentiation is under 5%, higher essentials for under 1%;
Speedy: shaft drive is at times used in the arranging capacity, which expects that it similarly has a particular degree of speed.

Elements of servo engine

The mechanical characteristics of the servo motor necessities: the servo engine is supposed to have a little speed drop, in a particular speed reach can keep a reliable power result, and static robustness.
The need to achieve fast control response: prevalently in the shape dealing with, especially the curve of the taking care of article for high speed dealing with, the servo motor speed, and power control response time has very extreme necessities.
The real motor has a broad assortment of speed rules: used to meet the CNC spindle gadgets changed in accordance with a great many instruments, taking care of workpiece materials, and can conform to an extensive variety of machining processes.
With over-trouble force result and consistent power yield capacity: machine gadget feed (servo motor) the possibility of the mechanical weight is generally to overcome the crushing of the table and cutting resistance, so the head “reliable power” nature, yet furthermore to gain a few short experiences force over-trouble limit. Like the standard servo motor accessible, the over-trouble breaking point can show up at various times or significantly more.

Distinction between shaft engine and servo engine

Distinction of standard
The shaft engine is an exactness nonconcurrent motor in light of the fact that CNC machine instruments have high necessities for development control, need to have extraordinary strong characteristics, colossal speed range and careful position control accuracy, so it needs a remarkable servo motor. The standard is comparable to the general squirrel bind motor, the best differentiation between the planned servo motor and the nonconcurrent motor is that the plan of the rotor is special. Composed motors have staggered posts on the rotor, and subsequently require relating area parts to distinguish the rotor position. While replacing these area parts furthermore ought to be revamped.

Differentiation of working reach
The servo motor works in the consistent power area between the least speed and assessed speed, while the shaft motor works in the predictable power district between the assessed speed and the most significant speed considering the way that to achieve a gigantic speed range, the assessed speed of the hub motor is overall extraordinarily low.

Contrast being utilized
The motor is used to distinguish the speed of the speed generator, the Entryway part similarly isolated on the framework of the motor to recognize the general spot of the rotor, while the shaft motor is used to recognize the motor speed with a position encoder, the motor encoder despite the conventional A, B, and R-stage sine cosine signal, there are two C-stage and D-stage sine cosine sign to recognize the spot of the motor rotor.
