Advantages of linear screw stepper motors used on machine tools. Linear screw stepper motor is a mechanism that converts rotary motion into linear motion, which consists of a screw, a nut and a ball.<\/span><\/p>\n

The advantages of linear screw stepper motors for machine tools are high precision, fast speed, simple mechanism and small size.\u00a0\"Tubular<\/a><\/span><\/p>\n

Advantages of linear screw stepper motors used on machine tools<\/span><\/strong><\/a><\/h2>\n

Due to the development of direct drive technology for linear screw stepper motors, the contrast between it and the traditional “rotary servo motor ball screw” drive method has attracted widespread attention in the motor industry. Now there are some technologically advanced machining center manufacturers that use it on high-speed machine tools. Because it has many advantages over the traditional way, we will now analyze it from three aspects;\"nema<\/span><\/p>\n

First, the accuracy aspect<\/span><\/strong><\/h2>\n

Linear stepper motor because of the simple transmission mechanism, so reduce the problem of interpolation hysteresis, its positioning accuracy, reproduction accuracy, absolute accuracy, have through position detection and feedback control, and “rotary servo motor ball screw” is higher, and easy to achieve.\"NEMA<\/span><\/p>\n

The positioning accuracy of linear stepper motors can reach up to 0.1\u03bcm.” Rotary servo motor ball screw” can reach up to 2~5\u03bcm, and requires CNC-servo motor-backlashless coupling-thrust bearing-cooling system-high-precision rolling guide-nut seat-table closed-loop transmission part of the whole system, to be lightweight, and its grating accuracy is high.\u00a0 \u00a0 \"NEMA<\/span><\/p>\n

If you want the motor to achieve high stability, the “rotary servo motor ball screw” should adopt a dual-axis drive method, and the linear screw stepper motor is to take forced cooling measures for high-heating parts, which may be more costly than to achieve the same purpose.\"NEMA<\/span><\/p>\n

Two. Speed-wise<\/span><\/strong><\/h2>\n

Compared with the traditional rotary servo motor ball screw, the linear screw stepper motor has great advantages. The running speed of the linear stepper motor reaches 300m\/min, and the acceleration can reach 10g; The ball screw runs at a speed of 120m\/min and accelerates only 1.5g.\"NEMA<\/span><\/p>\n

Just from the comparison between speed and acceleration, it can be seen that the linear screw stepper motor has great advantages, and after successfully solving the heating problem, the speed can be further improved, while the traditional “rotary servo motor ball screw” is limited in speed and is difficult to improve.\"height<\/span><\/p>\n

Three. In terms of longevity;<\/span><\/strong><\/h2>\n

Linear screw stepper motor<\/a><\/strong> because there is an installation gap between the moving parts and the fixed parts, but there is no contact, so it will not be worn due to the high-speed reciprocating motion of the mover, and the motion positioning accuracy is used for a long time, without much change, suitable for occasions that require high precision requirements.\"DC<\/span><\/p>\n

The ball screw motor cannot ensure the accuracy of the motor in the high-speed reciprocating motion, and because of the high-speed friction, the lead screw nut will be worn, which will affect the accuracy requirements of the motor movement. It cannot be met for applications that require high accuracy.<\/span><\/p>\n
