Description

The RW400F motor gearboxes with mounted frequency controllers are maintenance-free, compact drive units for operating ventilation and screen systems in greenhouses. These motor gearboxes enable a system to be driven at both "low" (normal) and "high" speed.¶The easily-installed RW400F motor gearboxes are controlled (rotational direction and speed) by switching of the digital inputs. This enables the two speeds ("low" and "high") to be controlled in both directions. Because the electronic components of the frequency controller are sealed in a housing with a high level of protection (IP65), the frequency controller is highly shielded from moisture and vibration. The frequency controllers have overload protection of the electric motor. The frequency controllers comply with the EMC directive (class A). The electric motors used as standard tropic-proof and conform to protection class IP55.¶The self-braking worm gear reduction of the RW400F motor gearboxes ensures that the drive shaft is braked when the drive is stopped. The combination of carefully matched pinion and worm reductions results in a very quiet mechanical transmission.¶The RW400F 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. For switching from the "high" to the "low" (normal) speed, an external switching signal is required.¶The RW400F motor gearboxes are finished in graphite-grey powder coating, and are supplied including fixing bolts and spring washers.
