Tips: What is the role of stepper motor in automatic door?

A. Introduction of automatic door

By configuring the intelligent control system for the automatic door, the running speed of the door leaf can be set randomly and semi-open state also can be set. It is convenient to adjust that the automatic door is always at best running state. Besides, with automatic correction function, even the running resistance causes by reasons such as heavy wind, the door can be opened and closed stably.
With automatic reverse safety device, when it is at under unusual condition like colliding into the barrier or human body, the door leaf will automatically be inverted and exit, and advance at safe speed when approaching the resistance region to avoid the occurrence of clamping person and destroying the parts; enhance the safety of automatic door when running and extend the service life of automatic door and it is easy to open the door. When at power outage, the elderly and children can open and close it easily. The opening and closing strength is below 3.5kg, so it is convenient, safe and reliable.

B. Role of stepper motor in automatic door

Stepper motor features efficiency, power saving, low noise, high rotational velocity, large torque and no overheating upon continuous usage, so it greatly exceeds traditional AC servo motor. With stepper motor drive and T-shaped gear synchronous belt, the door rotates exceptionally stably from low velocity to high velocity. With high performance power input, not matter how large the voltage amplitude is, automatic voltage regulation can be realized. Besides, in case of transient load short circuit, there are overvoltage and overcurrent protection measures to effectively guarantee the rotational stability, durability and safety of automatic door.
