Electric Height-Adjustable Desk

"Dual-Drive Synchronization · Silent Operation" — High-Torque Worm Gear Self-Locking Lifting System

Motor Types: DC Brushed Motor + Worm Gear Reducer / DC Brushless Motor + Electric Actuator

Application Case:
The core power source of the electric height-adjustable desk is the electric actuator or lifting column driven by a DC motor. The system typically employs two or more actuators operating synchronously, utilizing a 24VDC permanent magnet DC motor as the power source. Through the worm gear reduction mechanism, the motor's high-speed rotation is converted into low-speed, high-torque output, which is then transmitted via a lead screw-nut pair to achieve linear lifting motion. High-end solutions adopt brushless DC motors (BLDC) with built-in driver boards to enable intelligent control functions such as soft start, soft stop, and stroke limit detection. The motor's rated speed typically ranges from 2,800 to 4,300 rpm, with output speed reduced to 210–280 rpm after deceleration, delivering torque greater than 2.5 N·m.

Our Product Advantages:
- Equipped with a low-noise worm gear reducer, achieving overall noise levels below 50dB, meeting the quiet operation requirements for office and residential environments
- Built-in Hall sensors and optional optical encoders enable synchronized multi-desk lifting and position memory functionality
- BLDC solution supports PWM speed control, offering lower power consumption and extended service life (up to 200,000 cycles or more)

Addressing Market Pain Points:
Conventional height-adjustable desks suffer from issues such as asynchronous lifting, insufficient load capacity, and excessive noise. Our solution resolves the problems of desktop tilting and wobbling through a dual-actuator synchronous control algorithm and high-rigidity lead screw transmission. Meanwhile, the self-locking characteristic of the worm gear ensures that the desktop does not descend after a power outage, guaranteeing user safety.
