LG405 Gear Motor - The powerful solution for ventilation and screen system automation

The LG405 gear motor has been developed specially for the automatic opening of ventilation and screen systems in greenhouses. The construction of the gear motor makes it suitable for operation with the various existing rack-and-pinion systems.

Technically Sophisticated
In order to facilitate the installation, LG405 is a lightweight gear weighing just 19 kg (42 lb). It has a performance of up to 400 Nm. A standard flange motor is mounted on the gearbox so it is easy to disassemble without opening the gearbox. Potentiometers for position feedback can be built-in.

Double limit switch
The LG405 is equipped with a double limit switch. This provides extra safety against breakdown in cases of faulty connection or by fault in the associated motor relay. Interchange of the phases during the installation may damage one of the limit switches, but due to the double limit switch, switch number two ensures a correct stop of the motor.

Long lifespan
The selected materials and ball bearings give the gear a lifespan, which in many cases is as long as that of the greenhouse. Furthermore, the completely closed construction makes the gear maintenance-free.
