Shanghai four macro mechanical and electrical line transmission G4 is a new generation of high performance linear stepper motor series including 20 mm diameter, 25 mm and 35 mm of three kinds of specifications of the motor, the series motor has compact structure, stable performance, thrust, and many other priority, than on the market at present all the same size of the motor is much superior. G4 series motors are in the process of design and manufacture are to improve the performance and service life as the goal, USES perfect stator tooth, neodymium magnets, the rotation of the large size of the spline shaft, and can provide better support and higher axial load capacity increasing of ball bearings in place to ensure that products in the whole service life can keep free maintenance and repeat positioning accuracy. G4 provides exceptionally high thrust - permanent magnet motorSize than that in many in precision components of the request the installation space is not choice, such as medical equipment, scientific instruments, scanning equipment, printing equipment, and other precision optical instruments. Each contains a fixed size of motor shaft, well versed in shaft, the external drive type three kinds of forms, and each kind of motor can choose according to need to sync long screw, screw trip also can according to need to capture different length. the main products: stepper motor, brushless motor, servo motor, stepping motor drive, brake motor, linear motor and other kinds of models of the stepper motor, welcome to inquire.
