Flat Linear Motor Hardware Manual Product Overview The BLMF flat linear motor is a unique transmission system that provides extremely fast response with speeds up to 400in/sec (10m/sec) and exceptional positioning accuracy. Resolution and accuracy of the motors are limited only by the user’s position transducer, bearing, and servo control. The motor construction consists of a forcer and a rare earth magnet track that eliminates backlash, windup, and wear most commonly associated with ball screws, belts, or racks. Flat linear motors can be incorporated into gantry systems or positioning...

Flat Linear Motor Hardware Manual The motor case temperature can pose a burn hazard. Do not touch the motor until it has cooled sufficiently. These motors are not rated for use in explosive atmospheres. They are not to be operated in the presence of potentially explosive mixtures of air-borne dust or combustible vapors. Motors and their associated drives, cabling, etc. are sources of electromagnetic fields. Persons with external or implanted medical devices need to evaluate the risks associated with these devices before entering an area where they are in use.

Flat Linear Motor Hardware Manual 1.3. Motor Assembly and Installation The linear motor can be configured in two different ways. The magnet track can be held stationary while the forcer moves or the forcer can be held stationary while the magnet track moves. Use extreme caution when mounting the BLMFS & BLMFS5 forcer. The forcer will clamp to the track with extreme force if allowed to do so. Attach the forcer rigidly in its’ mounting position working away from the track not above it. The forcer and track have to be rigidly mounted before allowing the forcer to move into position over the...

Flat Linear Motor Hardware Manual 1.3.1. Bearing System The flat linear motor arrangement and load must be supported by a linear bearing system. The bearing system must be capable of supporting the forcer, the load, and, in the case of using BLMFS and BLMFS5 forcers, a considerable magnetic attractive force between the forcer and the magnet track. 1.3.2. Straightness and Flatness Requirements Straightness and flatness tolerances are deviations from a straight line in two dimensions. There are two separate alignment tolerances: straightness (side-to-side), and flatness (air gap) of the...

Flat Linear Motor Hardware Manual 1.3.4. Track Stacking To increase the linear motor travel distance, magnet tracks can be stacked end-to-end as shown in Figure 1-3. Stacking Tracks 1.3.5. Position Transducer Resolution The motion controller requires the use of a position transducer for all forms of motion control. This is typically a linear encoder. The specific application determines the encoder resolution. 1.3.6. Cable Management A high-flex cable management system must be used to connect the forcer and feedback signals to the stationary motion controller. The cable that exits the BLMF...

Flat Linear Motor Hardware Manual 1.4. Motor Wiring The forcer is supplied with flying leads for the motor winding, Hall effect devices, and thermal overload sensor. The customer supplies all external wiring to interface with these devices. This supplied wiring must meet certain requirements to provide for safe and reliable operation. The wiring must be able to supply the rated current without overheating. The wire insulation must be rated for the voltage and temperature at which the motor is operating. And, efforts must also be made to reduce EMI emissions and to increase EMI immunity...
