Schaeffler unveils L2U synchronous linear motors
A
Schaeffler (UK) product story
Edited by the Engineeringtalk editorial team
Sep 10, 2008
The Schaeffler Group has launched the Idam L2U range of synchronous linear motors that offer peak loads of 13,000N and deadweight of 45kg.
Schaeffler said the motors are ideal for use on large machining centres.
The primary advantage of this motor technology is that it compensates for any magnetic forces generated between motors and magnets.
The resulting unloading force leads to a longer service life.
In addition, accuracies are maintained for longer periods and friction-induced heat generation is reduced.
Schaeffler has achieved this by using an iron-core linear AC synchronous motor with two symmetrically opposed secondary parts.
The reduced iron content in the movable primary component further reduces the mass in the three-phase motor.
The lower deadweight of the L2U motors, relative to the payload, has a positive effect for highly dynamic applications with relatively low payloads (up to 10 times the mass of the primary part).
