Introduction of Nema 34 Linear Actuators


According to the daily assembly parts, Nema 34 linear actuator can usually be composed of a stepper motor and a screw, so its characteristics are similar to those of a stepper motor, and it can also be used in the field of industrial automation and robotics. According to the screw The characteristics of the motor can also change the rotary motion of the motor into linear motion.

What does NEMA 34 mean?

Nema 34 is named according to the shell size of the linear actuator, which is the same as the stepper motor, with a diameter of 86mm, and the step angle is similar to that of the 86 stepper motor, with 1.8° and 0.9°. Our motors also have the following features: high precision, low noise, good quality, etc. Our products can also be customized, so if you are interested, you can contact us at any time.

Application field of Nema 34 Linear Actuator

As the name suggests, the linear actuator can convert three-dimensional motion into a linear motion motor, and has the characteristics of high precision, so the design will be more complicated, but the linear actuator has high reliability, in the automatic production line, CNC, textile Machinery and other fields have a strong role.

Classification of Nema 34 linear actuators

1. Classification according to screw diameter

According to the classification of diameter, there are many models according to the size of the motor shell. We also have other types of linear actuators. If you are interested, please contact us!

2. Classified according to screw pitch

According to the different requirements of the load and the difference in the application field, we will also classify according to the screw pitch. We have been specializing in the production of motors for many years. We have our own factory and our own professional team and technical consultants. If you have any questions about the products, please feel free to contact us. You can come to consult us!

3. Classified according to the driving mode

If the linear actuator is classified according to the driving mode, it can be subdivided into direct drive and indirect drive. Direct drive can operate with higher precision, but the design will be relatively complicated.

4. Classification according to screw type

Linear actuators can also be divided into threaded screw and ball screw, but the accuracy of the ball screw will be higher, but the relative price will be more expensive.

How the Nema 34 Lead linear actuator Works

The working principle of the linear actuator is to convert the rotational motion of the motor into the linear motion of the screw, thereby driving the linear motion of the load. The basic principle of the linear actuator is that the screw and the nut are engaged, and a certain method is used to prevent the relative rotation of the screw and the nut, so that the screw can move axially. Generally speaking, there are two ways to achieve this transformation. One is to build a rotor with internal threads inside the motor, and the internal threads of the rotor mesh with the screw to achieve linear motion. The second is to use the screw as the output shaft of the motor, and the external drive nut on the outside of the motor is engaged with the screw to achieve linear motion. The motor usually converts rotary motion into linear motion through a screw pair transmission. The screw pair usually consists of a threaded screw and a nut. The threaded screw is usually fixed on the motor, and the nut is connected to the load.

In short, the linear actuator realizes linear motion control with high precision, high reliability and good stability by converting the rotational motion of the motor into linear motion, so it is widely used in the fields of industrial automation and robotics.
