Ridder Tubemotor System

The Ridder RB50Eᵖˡᵘˢ tubular motor is a maintenance-free drive unit for driving roll-up screen systems in greenhouses and livestock houses. The tube motor is integrated as standard into a 50 mm aluminium tube (wall thickness 1.5 mm) and can be used with 50 mm roll tubes. Because it is integrated, the tube motor can be wound up completely.

The almost-silent RB50Eᵖˡᵘˢ tube motor is fitted with a 1-phase 2-core asynchronous electric motor, an integrated brake and permanently lubricated planetary gear unit. The tube motor has a self-repairing thermal protection system, which prevents the burn-out of the drive if the electric motor should overheat.

The RB50Eᵖˡᵘˢ tube motor is almost entirely water resistant. The high protection class, IP55, means that the function of the tube motor will not be affected by a damp atmosphere.

The RB50Eᵖˡᵘˢ tube motor has as standard an intelligent and precision pulse-counting electronic limit-switch system with a range of 38 revolutions. This pulse-counter switches off the tube motor when it reaches its end position and also switches it off for safety reasons in the case of an overload. The switch components in the new electronic limit-switch system allow several tube motors to be connected in parallel without using an isolating relay.
Installing the RB50Eᵖˡᵘˢ tube motor is quite simple. In combination with the Ridder guiding unit and guide rail, the tube motor can be fitted in a roller screen system, both right and left.

  • Drive torque of 50 Nm at 50 Hz
  • Revolutions of 3.5 rpm at 50 Hz
  • Suitable for intermittent use, operating class s3-6%, duty cycle (kb) 10 minutes
  • Supplied in accordance with protection class IP55
  • Reliable motor brake behaviour, also when operating with undervoltage
