Application of linear screw stepper motor in foreign manufacturing equipment industry First in machine tool equipment, linear screw stepper motor drive technology can ensure a very high level of performance and higher simplicity than the traditional motor drive device that converts rotary motion into linear motion. Because the linear motor is directly connected to the moving load, there is no back gap between the motor and the load, and the compliance is very small.

Linear screw stepper motor in machine tool equipment application advantages are as follows:

1, the use of linear drive device can be very capacity to achieve less than 1μm/s or up to 5m/s speed. The linear drive system guarantees constant speed characteristics with a speed deviation of better than ±0.01%. In applications that require higher acceleration, smaller linear lead stepper motors can conveniently provide an acceleration greater than 10g, while conventional motors generally produce acceleration in the 1g range.

2. The linear screw stepper motor has a simple structure and is composed of few components, so it requires less lubrication (linear guide rails need regular lubrication). This means a longer service life and cleaner operation. In contrast, a conventional drive system consists of more than 20 components, including motors, couplings, ball screws, U-shaped blocks, bearings, pillow blocks and lubrication systems.

Other advantages of linear screw stepper motors include lower forces and smaller speed ripples, which ensures a smoother motion profile. Of course, this depends on the structure of the motor, the magnetic plate and the driving software. In order to take advantage of the dynamic braking inherent in linear screw stepper motors, the drive amplifier should effectively monitor the reverse electromotive force (EMF), even if the system power supply may be turned off. Multiple linear screw stepper motors can be installed "back to back" to ensure increased force. Additional magnetic plates can also be added to ensure substantial unlimited travel (limited by feedback devices and cable length) without loss of accuracy.
