Alpha WSER50 OD 30/17 (Obstacle Detection) Motor

⚠️ This is a 240V hardwired motor and requires an electrician for wiring. If you need a battery motor, see the WSERD series HERE.

The Alpha WSER50 OD 30/17 (Obstacle Detection) Motor is a premium automation solution engineered specifically for ZIP screens, external straight-drop blinds, and outdoor shading systems requiring intelligent obstruction safety. Delivering 30Nm torque at 17rpm, the motor provides exceptional strength, smooth operation, and advanced logic designed for Australia’s demanding outdoor conditions.

Unlike standard tubular motors, the Alpha WSER50 OD 30/17 (Obstacle Detection) Motor includes full bi-directional obstacle detection, allowing the system to react instantly when movement is restricted. When travelling downward, if the bottom bar stops due to an obstruction or becomes jammed in the side channel, the motor automatically rebounds and attempts to close again. After three failed attempts, it stops safely at the rebound point. If wind resistance—not a solid object—is detected, the motor reverses to the top limit, protecting both the fabric and the hardware.

The motor also incorporates torque-stop technology on upward movement, enabling blinds to stop on top stoppers and tension fabric correctly—ideal for external ZIP systems. A unique star-shaped motor head ensures compatibility with mountings used by multiple blind manufacturers, providing exceptional flexibility for both retrofits and new installations.

Equipped with a built-in receiver, wireless limit setting, electronic limit switches, and an external antenna, the Alpha WSER50 OD 30/17 (Obstacle Detection) Motor delivers strong signal range, installer efficiency, and reliable automation. Sensor integration adds further safety: if paired with wind sensors and the motor does not receive a heartbeat signal for approximately 30 minutes, the system assumes wind obstruction and retracts completely for protection.

This is one of the most advanced motors Alpha has released—ideal for homeowners and installers seeking automation with maximum safety, precision, and compatibility.

FAQs

What is the obstacle detection feature on the Alpha WSER50 OD 30/17 (Obstacle Detection) Motor?

The motor detects when the bottom bar stops moving during downward travel. It rebounds, retries up to three times, and stops if an obstacle persists. It protects the system from damage and prevents fabric bunching.

Is the Alpha WSER50 OD 30/17 (Obstacle Detection) Motor suitable for ZIP screens?

Yes—this motor is specifically designed for ZIP systems, using torque stop on upward travel and obstacle detection on downward travel.

Does this motor work with wind sensors?

Yes. When paired with RS001/RS002 sensors, the motor automatically retracts if the sensor’s heartbeat signal is lost for 30 minutes.

What does the star-shaped motor head do?

It fits a variety of mounting brackets used across different manufacturers, making installation easier and more compatible than standard motor heads.

How do you set limits on the Alpha WSER50 OD 30/17 (Obstacle Detection) Motor?

Limits are set wirelessly via Alpha remotes. The electronic limit switch system allows accurate, repeatable settings.

What torque and speed does the motor have?

The motor provides 30Nm torque and 17rpm, suitable for medium to large outdoor blinds.
