1: Characteristics of linear motor:
â— High acceleration,
â— High response speed,
â— High speed,
â— High stability,
â— Long stroke,
â— No contact with the mover/stator
â— Zero backlash direct drive technology,
â— Less mechanical parts, low complexity, easy maintenance and operation,
â— Apply to cruel environments such as vacuum.
2: Characteristics of Linear Motor Modules/Platforms:
â—: Linear motor drive â—: Linear scale positioning â—: High stability, high reliability, high response speed â—: No direct contact operation of the mover/stator â—: No backlash error â—: High accuracy, high acceleration, high moving speed â—:Smooth movement, no wear, minimal maintenance, long service life â—: Compact modular design, easy to expand â—: Quick combination of robotic arm, XYZ and XY cross platform/module and drive gantry system â—: Allowable Axis Multiple independent movers â—: Long stroke, maximum stroke 4 m or more â—: Maximum movement speed 5 m/s or more
3: The advantages of linear motors:
1: high stiffness:
â— I-type structure with high rigidity can act as a mover with greater thrust.
2: No core, not attractive to magnets:
â— More convenient and safer assembly and operation, smoother movement (no cogging).
â—Using special heat-conducting resin to match coil windings, the heat dissipation performance is even better.
3: Use vacuum packaging process:
â— It can still work normally in high vacuum environment.
4: Rail design modularization:
â— The length of the stroke is not limited.
5: Embedded over-temperature protector or thermistor indication:
â— Effectively prevent the coil winding temperature from being too high.
6: ultra-flexible motor cable:
â— The cable has a long service life.
4: The comparison between linear motor and traditional rotary motor has the following features:
â—1 The structure is simple:
Since the linear motor does not need an additional device that converts rotational motion into linear motion, the structure of the system itself is greatly improved.
Simplified, greatly reduced weight and volume;
â—2 High positioning accuracy:
Where linear motion is required, the linear motor can achieve direct transmission and thus eliminate the intermediate links
Positioning error, so the positioning accuracy, such as the use of computer control, you can also greatly improve the positioning accuracy of the entire system;
â— 3 fast response, high sensitivity, good follow-up:
The linear motor is easily supported by the magnetic levitation of its mover, so that the air gap between the mover and the stator is always maintained.
Without contact, this eliminates the contact friction between the stator and the mover, thus greatly improving the system's sensitivity, rapidity, and follow-up;
â—4 Safe and reliable work and long life:
The linear motor can realize the non-contact transmission force, the mechanical friction loss is almost zero, so the failure is less, maintenance-free, and therefore
For safety and long life.
