Generally speaking, when choosing a sliding table with linear modules, one may encounter an important parameter “reed”, which has also been asked by many friends recently. The Broadway Technology editor will elaborate here this time.

Lead: Lead refers to the distance that the linear module slider can move when a servo or stepper motor rotates one revolution, which is called the lead (supplementary, the pitch of the ball screw is called the lead). Why do we need such parameters? Pins are important parameters for calculating the operating speed of the linear module, and therefore play a significant role in selection and application.

What does linear module sliding guide mean?

For example, if the wire of the linear module is 20, the slider can follow the formula: wire x motor speed per second=maximum operating speed.

I know the lead is 20, but what is the speed of the motor per second? The servo motor is converted to seconds at a speed of 3000 rpm, resulting in 3000 ÷ 60=50 rpm. The data is substituted into the formula: 20X50=1000MM/S. When the stepper motor is converted to 600 revolutions per minute in seconds, it is 600 ÷ 60=10 revolutions per second, and the substitute formula is: 20 * 10=200MM/S.

When the motor speed is the same, the larger the lead, the faster the speed, and the smaller the lead, the slower the speed.
