In brief: Bei mechanischen Rohrmotoren werden die Endlagen mit Stellschrauben am Motorkopf eingestellt, die Bedienung erfolgt per Wandschalter. Elektronische Motoren speichern Endlagen per Sender oder Schalterfolge und bieten Extras wie Hinderniserkennung, Zwischenpositionen und Funk. Mechanisch ist günstiger und robust, elektronisch komfortabler.
Comparison
| mechanical | Electronic | |
|---|---|---|
| Setting the end positions | adjusting screws on the motor head | via transmitter or switch sequence |
| Operation | Blind switch | Radio hand transmitter, timer, sensors |
| Obstacle detection | no | often yes |
| Several motors on one switch | only with isolating relay | via radio group |
| Example | A-OK AM45 mechanical, ab 65 € | A-OK AM45 radio, ab 100 € |
Which motor for which case?
- Mechanical: simple roller shutters with wall switch, replacement for an old switch-operated motor, small budget.
- Electronic: convenience, smart home, automation with sensors, delicate curtains or plants on the windowsill.
The A-OK AM35 for small shafts is available in both versions; the AM55 for external venetian blinds always works with electronic end positions.
Setting end positions step by step: Connecting a roller shutter motor.
Frequently asked questions
Can I switch from mechanical to electronic?
Yes, by replacing the motor. The shaft stays; the adapters must fit the new motor.
Are electronic motors more prone to faults?
Not generally. They have more functions; the mechanics are comparable.
