Higher Cost Effective Non Magnetic Track Linear Motor for IC Package

What is magnetic-track-free linear motor?

Linear motor moves by the magnetic force produced by the magnetic field between stator and mover, so the mover and the stator are untouched. For the conventional linear motors, whether for the iron core or the ironless core linear motors, they need to lay the magnetic track built by the permanent magnets on the stator, so the motor can move by the magnetic force produced by the coil-generated magnetic field and the PM generated magnetic field.

ALM proposed the Magnetic-track-free (MTF) linear motor for the first time in industry based on the innovation in the magnetic field theory. Remarkably, the stator does not need the magnetic track anymore, which can save the massive rare-earth materials. By iteratively optimizing the design and the manufacturing craft, MTF linear motor obtained the extremely high force density, operating speed and moving precision.

ADVANTAGES OF magnetic-track-free LINEAR MOTORS

Not only with the advantages of high precision and high speed of normal linear motor, but also with the following obvious advantages.

MORE SAFE：No magnetic field in stator, easier for assembling, much lower risk for operators

MUCH SMALLER ATTRACTION FORCE: About ⅓ of the conventional linear motor attraction force can reduce the friction and cogging force significantly, thus to increase the life expectancy and reduce the operating noise.

MUCH SMALLER COGGING FORCE: Benefited from the low attraction force and the specialized optimizing design, MTF-LM can obtain the extremely low cogging force.

MORE ADAPTIVE：With low requirement for the ingress protection, and reduce the EMI grade obviously

EASIER FOR PROTECTION：Not easy to attract the sundries and ashes into the motor, easier for protection

HIGHER COST-EFFECTIVE：Benefited from the rare-earth material saving, MTF is trying to provide the most cost-effective products for customers.
