The stator of the magnetic-track-free(MTF)linear motor does not use magnets,but the powder magnetic conductive materials.This material with the features of high permeability,high saturation flux and is easy to manufacture by metallurgical die casting.MTF linear motors put the magnet inside the actuator,and when the actuator moves,the corresponding magnet moves.That is,the motor will have the excitation of the magnet with movement,the magnet movement to which part,which part of the electromagnetic force.Thus,as the rotary permanent magnet synchronous motor,the magnet utilization rate reaches 100%,no extra magnet is exposed.As a result,the cost of linear motors is greatly reduced and safety is improved.

●MTF Linear Motor Advantages
More Safe
No magnetic field in stator,easier for assembling,much lower risk for operators.
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.
Much Smaller Attraction Force
About ⅓ of the conventional linear motor attraction force can reduce the attraction force significantly,thus to increase the life expectancy and reduce operating noise.
Much Smaller Cogging Force
Benefited from the low attraction force and the specialized optimizing design,MTF linear motor can obtain the extremely low cogging force.
