The basic composition of the power system
The power system of the electric lifttable is mainly composed of three parts: the motor, the reducer and the mechanical transmission device. The motor is the power source of the entire system, responsible for providing the necessary energy to drive the desktop to rise and fall; the reducer plays the role of adjusting the speed and increasing the torque to ensure the stability and efficiency of the power transmission process; and the mechanical transmission device, such as the screw, gear or belt, is the key component that converts the rotational motion of the motor into linear motion, directly acting on the desktop to achieve the lifting function.

The role and type of the motor
As the heart of the electric lifttable, the performance of the motor directly affects the lifting speed, stability and energy consumption of the desktop. In the electric lifttable, the commonly used types of motors include DC motors and AC motors. DC motors are more common in applications that require precise control and fast response due to their simple control, wide speed regulation range and fast response speed. The AC motor has a place in cost-sensitive products with its advantages of simple structure, low maintenance cost and reliable operation.

The motor starts and generates rotational motion by receiving instructions from the controller. This rotational motion is converted into linear motion through a mechanical transmission device, pushing the desktop up or down. The selection and design of the motor must fully consider factors such as load size, lifting speed requirements, and energy efficiency to achieve the best performance match.

The role and importance of the reducer
The reducer plays a vital role in the power system of the electric lifttable. It is located between the motor and the mechanical transmission device. Its main function is to reduce the output speed of the motor and increase the output torque accordingly. This conversion process is crucial to achieve smooth lifting of the desktop. The high-speed and low-torque motor directly drives the desktop, which often causes jitter and instability during the lifting process. The reducer reduces the speed and increases the torque, allowing the desktop to rise and fall at a more stable and uniform speed, greatly improving the user experience.

In addition, the reducer can effectively protect the motor from overload damage and extend its service life. In the event of sudden load changes or abnormal conditions, the reducer can absorb and buffer this part of the impact force to ensure the stable operation of the entire power system.

Selection and optimization of mechanical transmission devices
As a bridge between the motor and the desktop, the type and structure of the mechanical transmission device directly affect the lifting efficiency and accuracy. Screw drive is widely used in electric lift tables that require precise positioning due to its high precision, low noise, and strong self-locking properties. Gear drive is suitable for occasions with large loads due to its high transmission efficiency and compact structure. Belt drive is more common in entry-level electric lift tables due to its low cost and easy maintenance.

When designing an electric lift table, it is necessary to select a suitable mechanical transmission device according to specific needs, and further improve the transmission efficiency and reduce noise by optimizing the transmission ratio, material selection, and lubrication method to ensure smooth lifting of the desktop.
