The EP-45 motor gearboxes are maintenance-free, compact drive units for operating ventilation, screen and flap MOTOR WORM GEARBOXES FOR GREENHOUSE GW80 CHAIN COUPLING ventilation systems in greenhouses and livestock houses. The EP-45 engine gearboxes are created to work at ambient temps between 0 and 60 °C.
All EP-45 electric motor gearboxes include a self-braking worm gear transmission. The EP- motor gearbox's self-braking worm gear transmission ensures that the result shaft can be braked when the drive device is stopped. The combination of properly matched pinion and worm reductions results in a very quiet mechanical transmission.
The EP-45 
electric motor gearboxes feature a patented integrated linear limit-switch system with duty and safety switches having excellent switching precision. The maximum switching range of the limit-switch program equates to 97 revolutions of the drive shaft. The optional RPU PositioningUnit accurately monitors the existing placement of a drive system and transmits this data back to your climate pc or controller. This position feedback may also be achieved using an installation arranged with a potentiometer.
The EP-45 electric motor gearboxes are finished with a graphite grey powder coating and are supplied including fixing bolts and spring washers.
