Abstract (en)
[origin: WO0237652A1] In the synchronous linear motor (10), the coil block (20) exhibits low inertia and therefore good dynamic performance, thanks to being constrained to slide with respect to the support structure (11), which comprises a plurality of magnets (13), on a single mechanical guide (16), which is arranged advantageously on an opposite wall with respect to the fixed magnets, which are immobile. The solution of the invention, especially suitable for actuating tool chucks, also offers high-level protection with regard both to external impurities and to the magnetic field emitted by the magnets themselves. The support structure (11) of the motor can be of a closed type with four sides.
