Linear Motor

Application industry:

3D Scanner, Image Scanning, Laser Testing, High-end automation equipment, LCD panel high-speed laser drilling machine, all-linear motor six-axis CNC drilling machine, high-speed and high-precision SMT mounter, high-speed transplanting equipment

Before the advent of practical and affordable linear motors, all linear motion had to be converted from rotating machinery by using ball or roller screw or belt or pulley. For many applications, such as heavy load and the drive shaft is vertical. These methods are still the best. However, linear motor has many unique advantages over mechanical system, such as very high speed and very low speed, high acceleration, almost zero maintenance (no contact parts), high precision and no idle return. To complete the linear motion, only the motor is needed, and there is no gear, coupling or pulley. It is very meaningful for many applications. Those unnecessary parts that reduce performance and shorten mechanical life are removed.

Basic Information:

Maximum acceleration: 4G
Ultra-high absolute positioning accuracy <1 min
Full closed loop feedback system
Anti-deformation and vibration design
Core-free vibration (Yaskawa: 0.4; Jacobs: 0.76; hiwin: 0.8)
Setting time is short: the test method is running 0-30.30-0 back movement, which takes 0.052s

Features:

1. Few parts, all can be modular packed and then shipped.
2. The assembly is simple, do not need skilled workers, just need to tighten the screws.
3. Accessories have a high versatility, the same width of the product, except the main carriage module, other materials are all universal.

Our Service:

1. We can provide the whole parts, including mechanical parts, forcer, stator, raster, magnetic grating, driver.
2. Provide calculation tables for pre-sales selection
3. Provide Panasonic installation and commissioning technical guidance.
4. Provide technical guidance for unit assembly and raster installation.

Suitable for handling occasions:

where needs fast speed, long stroke, maximum load within 100KGS, and replace the occasions where use the timing belt & rack and pinion.

Suitable for high precision required occasion:

can be matched with raster ruler, and replace the occasions where use C3 grade grinding ball screw.
PS: No matter raster or magnetic grating, the repetition accuracy can be achieved within ±0.002. They differ mainly in absolute positioning accuracy. If you run a repeat position, recommend to use magnetic grating.

Suitable for high acceleration occasions of emergency stop and walk:

linear motor can generally reach more than 1G, while ball screw can only reach 0.5G.
