Tips: Linear screw stepper motor VS Ball screw rotating servo motor

Precision: Linear screw stepper motor reduces the problem of interpolation lagging because of simple transmission gear structure. The positioning accuracy, accuracy reappearance, absolute accuracy are higher than the ball screw rotary servo motor through position detection feedback control and it is easy to achieved. The positioning precision of the linear screw stepper motor can reach 0.1μm while the precision of ball screw rotating servo motor can reach a maximum of 2~5μm.
Speed: The speed of the linear stepper motor can reach 300m/min and the accelerated speed can reach 10g. The ball screw speed is 120m/min and the accelerated speed is 1.5g. Linear screw stepper motor has considerable advantages from the contrast of speed and the accelerated speed. The speed of linear screw stepper motor will be further improved after solving the heating problem successfully.
Service Life: There is installation clearance between the moving parts and the fixed parts and they have no contact. The linear screw stepper motor will not be worn out due to high speed reciprocating motion of the active cell. The motion positioning accuracy will keep unchanged for long-term use and it is suitable for high precision occasions. The ball screw rotating servo motor cannot guarantee the accuracy in high speed reciprocating motion because high speed friction will cause wear of the screw nut and affect the precision requirement for movement. That is the demand for high precision it cannot be met.

ATO external stepper linear actuator in this video is 2 phase 4 wire comes in Nema 23 frame size. We will show you how to use PLC connect to the hybrid stepper motor system, and control this external stepper motor linear actuator for simple forward and reverse motion by the pulse and direction command issued by PLC.

In this video we've guided you through how to do VFD control wiring with a self-lock push button switch to run the motor in forward direction. We've covered everything from wiring to programming and even a test run. So just watch it through and hope you'll find it informative and helpful.

Calculation of Lead Screw and Stepper Motor

This video introduces the calculation of stepper motor. You need to know the step angle of the stepper motor and the pitch of the lead screw as well as the number of threads and subdivisions of the driver.

Rotation Angle Control of Stepper Motor

The angle control principle of stepper motor is to control the number of pulse outputs of PLC.

1. The output frequency of PLC is related to the speed of motor.

2. Pay attention to the dip switch on the stepper motor driver, which should match the current of stepper motor, and pay attention to how many pulses control the stepper motor to rotate one circle.

1.8 degree stepper motor teardown & construction display

In the case of non-overload, the speed and stop position of the motor only depend on the frequency and pulse number of the pulse signal, and are not affected by the load change. That is, when a pulse signal is added to the motor, the motor rotates through a step angle. The existence of this linear relationship, coupled with the characteristics of the stepper motor having only periodic errors and no cumulative errors. This makes it very simple to use stepper motors to control the speed, position and other control fields.

Question for Nema 17 stepper motor

Hi, just looking at this Nema 17 linear stepper motors, do either captive or non captive pass purely the screw through the motor housing. e.g would it be possible to lower something which the screw is attached to from the motor.

ATO Responded

Yes, for linear stepper motors, whether they are captive or non captive, the screws are built into the motor, this uses the Sawyer principle, and the built-in screw cannot be removed.
