Are you new to micro linear actuator motors? Have you just learned what a micro linear actuator motor is? You’re not alone, and we’re happy to help! This article is for you, and we will try to provide you with more information that you need to make an educated decision when deciding on what miniature linear actuator motor is right for you.
Part1: Brief Introduction of Micro Linear Actuator Motor (Lifting System)
Simply put, a micro linear actuator motor is a piece of equipment that turns rotational motion into linear motion, through the application of linear force. The electric linear actuator is a linear lifting device that mainly consists of motor, lead screw, control system, which can realize remote control, centralized control. The rod of the electric actuator makes round-trip lifting movement within certain range of distance. It is also referred to as mini linear actuators or miniature linear actuators that produce mechanical linear motion through the conversion of various forms of energy into mechanical energy. They work in much the same way as large-scale actuators, but are physically smaller in size. This makes them more suitable to tight spaces and applications where weight must be kept to a minimum. There is no hard and fast rule for what makes an actuator ‘micro’ but generally speaking the standard travel range of regular linear actuator is less than 400mm. Special travel range can be customized according to different applications.
There are many different ways that a micro linear actuator motor can do this, and their motion is commonly achieved with a rod extending and retracting, or a slider which moves on a track. Uses for these linear motors widely vary, and they can be mainly used in the applications that need lifting systems.
ZHAOWEI transmits the instructions to the mechanical structure through the lifting gearbox module control system, so that the circular motion of the motor is converted into the linear motion of the linear actuator, achieving pushing&pulling and lifting heavy objects. This linear drive lifting module solution can be used in various intelligent linear drive terminal fields, such as medical beds and nursing beds, sit-stand desks and diverse equipment for industrial and agricultural automation. ZHAOWEI provides customers with various electric linear actuators, lifting columns and related gear motor accessories, which can be customized for development.
Part2: Advantages of Micro Linear Actuator Motor
There are plenty of advantages of micro linear actuator motors with the help of advanced technology. Here we take ZHAOWEI as an example. There are many smart electric lifting desks on the current market, but there are still some problems such as insufficient load bearing, limited switchable gear(lifting range), short service life, large power consumption, loud noise or even stuttering if the speed is not controlled well while lifting. By integrating the micro linear actuator motors produced by ZHAOWEI, those anxieties can be removed. Its micro linear drive lifting module solution enables compact size with no external control board. Precision design with large torque helps to deliver high performance in applications requiring continuous duty operation. Though it is small, it still has the strong power to drive your projects with low noise.

Part3: How Does the Micro Linear Actuator Motor Work? (Lifting System)
The micro linear actuator motor with lifting system of ZHAOWEI includes holder, drive assembly, transmission assembly, lead screw, guide rod and protection assembly. Lead screw and guide rod are mounted on the holder and their axes are parallel. The drive assembly is connected with the transmission assembly while the lead screw rotates through the transmission assembly. The protection assembly includes engaging part and elastic part, and the former consists of the engaging portions and fixed portions which are connected to each other. The fixed portion is sleeved on the guide rod to force the engaging portion to move along the guide rod. There is an opening on one side of the engaging part while the lead screw is set in the opening whose inner wall has a screw thread in coordination with the lead screw. The engaging part is driven by the screw thread and lead screw. One end of the elastic part is fixed to the engaging piece and the other end is against the lead screw. The engaging piece can rotate relative to the guide rod and the elastic potential energy of the elastic part is used to push the opening together with the screw.
The engaging part and elastic part are set to enable the engaging part to bounce off following the radial direction of the lead screw, so as to avoid the damage of the transmission component caused by excessive force on the lead screw. The whole working process of this kind of micro linear actuator motor leads to its good stability, strong synchronization performance, low noise and high torque.
Noted: If the teeth number of the sun gear and planetary gear is changed, then different reduction ratios can be achieved in each stage. ZHAOWEI lifting planetary gearbox offers 4 stages to achieve various reduction ratios that you need. Customization is available.
Which one of the micro linear actuator motor series can be your best choice? It depends on your needs like the working environment, required speed, required torque, etc. We hope that this has helped you develop a better understanding and foundation for micro linear actuator motors and their incorporation into linear motion systems.
