A-BLC Series Linear MotorsUSER MANUAL

documented. Claims for damage due to shipment are usually made against the 

transportation company. Also contact Anorad immediately for further advise.

Identify what options your linear motor is equipped with. Ensure the 

information listed on the purchase order correlates to the information on the 

packing slip that accompanied your motor components Verify that the quantity 

of magnet plates received matches your job requirements. Inspect the 

assemblies and confirm, if applicable, the presence of specified options.

ATTENTION

!

Linear Motors contain powerful permanent magnets which 

require extreme caution during handling. When handing 

multiple magnet plates do not allow the plates to come in 

contact with each other. Do not disassemble the magnet 

plates. The forces between plates are very powerful and can 

cause bodily injury. Persons with pacemakers or Automatic 

Implantable Cardiac Defibrillator (AICD) should maintain 

a minimum distance of 12 inches from magnet assemblies. 

Additionally, unless absolutely unavoidable, a minimum 

distance of 5 feet must be maintained between magnet 

assemblies and other magnetic/ferrous composite 

materials. Use only non-metallic instrumentation when 

verifying assembly dimension prior to installation (e.g. 

calipers, micrometers, laser equipment, etc.)

Identifying the Linear Motor 

Type

Coil Assembly (example)

1. Ensure the mounting surface to which the magnet plate is to be attached 

is clear of any and all foreign material. If necessary, stone the mounting 

surface (acetone or methanol may be applied as cleaning agent). 

Do not clean the surface using abrasives!

4. Position the moving slide to the end of travel that you wish the cable to 

exit. Making sure that the mounting face of the motor coil is clean and 

free of burrs, install the motor under the slide. Select a M5 x 0.8 bolt 

with a length that extends through the slide by 12 mm minimum, but 

not more then 20 mm. Tighten snugly for now, bolts will be torqued 

once installation is complete. 

5. On the opposite end of the base, install the first magnet plate using M5 

x 0.8 and 16 mm long SHCS. Non-magnetic tools and hardware 

(beryllium copper, 300 series stainless steel, etc.) should be use. If not 

available proceed with care since magnetic items will be attracted to the 

magnet plates. Do not tighten bolts at this time. Install additional 

magnet plates by placing them on the base and sliding towards the 

previous install plate. Orient the plates such that the alignment holes are 

toward the same side. This will ensure proper magnet polarity.

6. Move the slide, which you previously mounted motor coil to, over the 

magnet plate. There may be some resistance while moving onto the 

plate, this is normal. Measure the gap between the motor and magnet 

using plastic shim stock. The gap should be 0.79 mm (0.031 in.) to 

1.70 mm (0.067 in.). If gap is too large, add appropriate brass or stainless 

steel shim between motor and slide. If gap is to small, machine the slide 

or place shims under the bearing pucks.

7. Once the motor is gapped properly, install the remaining magnet plates. 

8. The final alignment of the magnet plates are done with an aluminum 

straight edge, and the alignment tool that was supplied with the magnet 

plates. Slightly loosen the magnet plate mounting bolts, but not the ones 

that are covered by the motor coil. Place the alignment tool in the holes 

on each of the plates, this will properly position the pitch of the plates. 

Align the edges of the plate with the aluminum straight edge and tighten 

the bolts

9. Position the slide over the complete sections and continue aligning the 

remainder of the plates. 

10. If the area where the magnet plates are to be installed does not allow you 

to use a straight edge describes above, an alternate method of aligning 

plates can be done. Space the plate by using a 0.020 plastic shim between 

the magnet plates, tighten the bolts, and then remove the shim. 

11. Once all the alignment is completed, torque all bolts to values listed in 

the tables.When considering torque values for mounting hardware, take 

into account the magnet plate, mounting surface and mounting 

hardware. Per Table 2.N secure all assemblies in place using all 

mounting holes.

ATTENTION

!

Remove alignment tool and make certain all magnet plate 

mounting hardware is flush or below magnet surface to 

prevent damage to the coil.

Motor/Hall Phasing and 

Sequence

See Figure 2.15 for the standard phase and sequence relationship of the LC 

series motors when phased in the specific motor direction. The Trapezoidal 

Hall signals are used by a compatible three phase brushless servo drive to 

perform electronic commutation. Two types of servo drive Hall-based 

commutation techniques are possible, Trapezoidal Hall Mode and Encoder 

(Software/Digital) Mode with Trapezoidal Hall start-up. Note: For optimal
