Linear stepper motor to linear motion or straight line reciprocating movement.
Rotary motor as power source, to turn into linear motion, need with the help of the gear, convex wheel structure and belt or steel wire.
Linear stepper motor, or linear stepper motor, is by the magnetic rotor iron core through interaction with the pulse electromagnetic field generated by the stator and rotating, the linear stepper motor inside the motor rotation movement into linear motion.
Compared with linear stepper motor and rotary type linear motion directly, can make the machine in miniaturization;
Sensitive to load inertia;
Such as long stroke, air gap will be bigger than rotary type, which will produce the problem such as inefficient, be especially careful when using it using purpose and using the environment and other aspects.
engages USES a screw and nut, take some way to prevent the screw nut relative rotation, so that the screw axial movement. In general, there are two ways of realizing this transformation, the first is a built-in with internal thread in motor rotor, engages with the internal thread of the rotor and the screw and linear motion, the second is the screw as a motor shaft, on the outside of the planetary gear motor through an external drives the nut and screw meshed to achieve linear motion. As a result, greatly simplifies the design make in many application fields in the case of not to install the external mechanical linkage directly using the linear stepper motor for precision linear motion.
seven advantages of linear stepper motor
( 1) High-speed responsiveness
in general mechanical transmission parts is bigger than the electrical components of the dynamic response time of several orders of magnitude. Due to large system cancelled some response time constant of mechanical transmission parts, such as screw the whole closed loop control system dynamic response performance is greatly improved, the response was unusually sensitive and quick.
（ 2) High precision sex
because the mechanical drive mechanism, such as cancel the screw insert and thus reduce the stoppage time lag of the tracking error for transmission system. Through linear position detection feedback control, can greatly improve the positioning precision of the machine tool.
（ 3) The high stiffness of thrust, smooth
& other; Direct drive & throughout; Improved its transmission stiffness. The layout of the linear motor at the same time, according to the shape of machine tool guideway surface structure and the force of the movement to the table layout. Usually designed to be uniform is symmetrical, smooth motor thrust.
（ 4) Speed and deceleration process short
linear motor is mainly used for the earliest maglev trains ( Speeds of up to 500 km/h) , now used in machine tool feed drive, to meet its ultra-high speed cutting feed speed (largest For up to 60 ~ 100 m/min or higher) Of course is no problem. Also because & other; Zero transmission & throughout; High-speed responsiveness, which greatly shorten the deceleration process, so as to realize starting instantly at high speed, high speed running and must stop instantly. Acceleration can reach 2 ~ 10 g ( g = 9。 8m/s2） 。
（ 5) Stroke length is not restricted
in the guide rail through a series of linear stepper motor on set pieces, can be unlimited extension of the moving parts of the stroke length.
（ 6) Low noise when running
due to cancel the mechanical friction drive screw and other parts, and the guide rolling guide can be used or mat of magnetic levitation guideway ( No mechanical contact) Noise drops greatly, make the movement.
（ 7) High efficiency
because no intermediate transmission links, has cancelled its mechanical friction energy loss.
the current linear stepper motor is widely used in including manufacturing, precision calibration, precision flow measurement, accurate position, and many other high precision requirements.
Zhenyu can also foster research that is more useful and influential in society at large.
