FIR Group, leader in design and development of custom motors

Slidingdoor FIR can provide both traditional AC and PM brushless motors for your Automatic Door Application. Sophisticated adjustable operating parameters offer you a wide range of options for your specific application.

Characteristics:

Self learning - The door opening as well as the door position “close” and “open,” are automatically registered, so travel switches are not necessary.
Emergency power supply - This assures the car will operate if commercial power is lost.

Motors for door operators

PM brushless motors have electronic four quadrant control. This system allows mechanics to simplify the automatic operator and regulate the speed as well as door opening and closure positions. Additionally, all signals (safety and open/close signals) on the operating panel are electronically managed. The system requires no supplementary limit switch or encoder.

Characteristics:

Reduced size
Extremely rigid
Reduced movement of the rotor
Reduced vibrations
High performance
Reduced weight
