Application advantages of linear screw stepping motor in machine tool equipment
The application advantages of linear screw stepping motor in machine tool equipment, the linear screw stepping motor drive technology can ensure a relatively high performance level and has higher simplicity than the traditional motor drive device that converts rotary motion into linear motion.
Since the linear motor is directly connected to the moving load, there is no back gap between the motor and the load, and the flexibility is very small.
The application advantages of linear screw stepping motor in machine tool equipment, Shenzhen ruite electromechanical Technology Co. , Ltd. is located in Shenzhen, Guangdong province, it is a stepping motor manufacturer integrating research and development, production and sales of stepping motor drivers, servo drivers, stepping motors, servo motors and spindle servo motors.
The advantages of linear screw stepping motor in machine tool equipment are as follows: 1. Using linear drive device can reach less than 1μ in capacityM/s or up to 5 m/s.
The linear drive system can ensure constant speed characteristics, and the speed deviation is better than ±0. 01%.
In applications requiring higher acceleration, smaller linear screw stepping motors can easily provide acceleration greater than 10g, while traditional motors generally generate acceleration within 1g.
2. The linear screw stepping motor has a simple structure and consists of few components, so less lubrication is required (Linear guide rail needs regular lubrication).
This means that its service life is longer and its operation is cleaner.
In contrast, the traditional drive system consists of more than 20 parts, including motor, coupling, ball screw, U-shaped block, bearing, pillow block and lubrication system.
Other advantages of linear screw stepping motor include lower acting force and smaller speed ripple, thus ensuring 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 inherent dynamic braking of linear screw stepping motors, the drive amplifier should effectively monitor the inverse electromotive force (EMF)Even if the system power supply may be turned off.
A plurality of linear screw stepping motors can be usedBack to Back'To ensure that the acting force is increased.
Additional magnetic plates can also be added to ensure substantial unlimited travel (Limited by feedback equipment and cable length)Without loss of accuracy.
