The electric drive EWA 50.0505, model number 12508.0505.1205, is designed for intermittent operation according to duty cycle S3–40%. It delivers a constant torque of 50 Nm at a speed of 4.5 rpm and operates on 400 V three-phase AC.

The integrated double worm gear is self-locking, enabling secure positioning without backdriving.

The We06 shaft, with a length of 280 mm, is built directly into the drive and is especially suitable for compact installations with limited space. It ensures reliable power transmission in minimal mounting space.

The END20.20 limit switch is factory-integrated and precisely matched to the motor. It enables accurate and safe end-position shutoff without additional installation effort.

With a protection rating of IP55, the drive is safeguarded against dust and water jets. The permissible ambient temperature range is between –5 °C and +60 °C.

This drive is ideal for greenhouse applications, particularly for controlling ventilation and shading systems.
