RW400 Motor gearboxes.


  • The RW400 motor gearboxes are maintenance-free, compact drive units for operating ventilation, screen and hoisting systems in greenhouses and livestock houses. The easy-to-install RW400 motor gearboxes are enclosed in a housing with a sealed limit-switch system that has a high protection rating of IP55. The RW400 motor gearboxes are designed to operate at ambient temperatures between 0 and 60 °C.
    All RW400 motor gearboxes feature a self-braking worm gear transmission. The RW motor-gearbox's self-braking worm gear transmission ensures that the output shaft is braked when the drive unit is stopped. The combination of carefully matched pinion and worm reductions results in a very quiet mechanical transmission.
    The RW400 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 system equates to 86 revolutions of the drive shaft. The optional RPU PositioningUnit accurately monitors the current position of a drive system and transmits this data back to your climate computer or controller. This position feedback can also be achieved using an installation set with a potentiometer.
    The RW400 motor gearboxes are finished with a graphite grey powder coating and are supplied including fixing bolts and spring washers.
