U type linear motor, linear motor structure is compact, small power consumption, quick move to the high velocity, high acceleration, high speed,Linear motor, by means of direct drive load can be achieved from high to low speed and high precision positioning control of different scope. Linear motor motion of (Primary)And the stator (Secondary)No direct contact between the stator and dynamic are rigid, and thus to ensure that the linear motor motion mute and high rigidity of whole body core moving parts. Linear motor stroke can be done by joining together the stator stroke unlimited, at the same time also can be in the same stator configure multiple active cell to achieve the same axial movement of multiple independent control. Linear motor driven mechanism can be enhanced as well as the feedback element stiffness and precision, supplemented by temperature control measures to achieve ultra precision motion control. ）Simple structure,, due to the linear motor don't need a rotation movement into linear motion of the additional device, thus making the structure of the system itself greatly simplified, weight and volume is greatly decreased; ）High positioning accuracy,In need to linear motion, linear motor can realize direct drive, it can eliminate the intermediate links of various positioning error, so the high positioning accuracy, such as using microcomputer control, can greatly increase the positioning accuracy of the whole system is also; ）Fast response, high sensitivity, good follow-up (Linear motor easy to do it by using magnetic levitation support, making the child and always maintain a certain air gap between the stator and do not contact, this eliminates the constant, dynamic contact between the friction resistance, thus greatly improves the system's sensitivity, rapidity and follow-up; ）Work safe and reliable, long life,Linear motor can realize non-contact and heritability of mechanical friction loss is almost zero, so less faults, maintenance free, thus work safe and reliable, long life. ）Low noise advantages, mode driven by linear motor and rotary motor drive mode is the biggest difference between, cancelled from motor to the workbench, among all the mechanical transmission link between implements & other; Zero transmission & throughout; , to avoid the reverse clearance of lead screw transmission, inertia, friction, and lack of rigid shortcomings, greatly improve the performance of machine tool. Other application industry is also widely used.
