Standard linear motors move along two axes
Researchers at Philips Applied Technologies, a subsidiary of Royal Philips Electronics of the Netherlands, have developed a way to let standard linear motors generate motion along two axes.
What they call
NForcer technology should reduce
the number of motors, electronic
drives, and the mass of moving parts,
thus delivering higher acceleration
and operating speeds.
In conventional motors, the conductors
are coils, with only their vertical sides in the magnetic field. As a
result, they only generate lateral motion.
To get two-dimensional motion
from one motor, the researchers
shifted the coils so the lower horizontal
part of the coils sits in the magnetic
field, where it generates force
and, consequently, vertical motion.
Researchers predict the technology
could control magnetic levitation,
leading to fully floating, bearing-
less platforms.
