Alpha WSER50 50/13 Cassette Awning Motor

The Alpha WSER50 50/13 Cassette Awning Motor is a powerful 240V tubular radio motor specifically designed for folding-arm and cassette awning systems.

Delivering 50Nm of rated torque at 13 rpm, this model provides substantially greater torque than the 30Nm WSER50 30/17 Cassette Awning Motor while retaining the specialised functionality required for cassette awning operation.

Its standout feature is the ability to automatically determine the inner or closed stopping position based on resistance as the awning closes.

The motor also incorporates electronic limits, a built-in radio receiver, wireless limit setting and an external antenna.

Automatic Inner Limit Setting

The Alpha WSER50 50/13 Cassette Awning Motor can automatically establish its inner stopping position based on the physical closure of the awning.

When using automatic inner-limit setting, the installer manually programs the outer or extended limit using the remote control.

The first time the awning is closed, the motor detects the resistance generated as the cassette reaches its fully closed position.

This allows the motor to determine its inner stopping position automatically.

For cassette awnings, this is particularly useful because the motor can respond to the physical closed position of the system rather than relying exclusively on a manually programmed inner limit.

Resistance-Based Closing

After the automatic inner limit has been established, the motor monitors resistance while closing.

Alpha specifies that the standard setting detects an increased resistance of 25% while the awning is moving.

When the required resistance is detected at the closed position, the motor stops.

This provides controlled closure of compatible cassette awnings while allowing the motor to respond to the actual resistance generated by the awning system.

Adjustable Resistance Sensitivity

Not every cassette awning requires the same amount of closing force.

This is particularly relevant with larger awning systems, where the standard 25% resistance setting may not always provide sufficient closing force.

The Alpha WSER50 50/13 therefore allows the resistance threshold to be adjusted to:

• 25%
• 50%
• 75%
• 100%

Alpha notes that increasing the setting is rarely required, but having the adjustment available provides additional flexibility for larger cassette awning systems.

Manual Inner Limit Setting

Automatic inner-limit detection isn’t compulsory.

The Alpha WSER50 50/13 Cassette Awning Motor also allows the inner limit to be set manually when required.

This gives installers the choice between resistance-based automatic closure and a manually programmed inner stopping position depending on the requirements of the particular awning.

Designed for Folding-Arm and Cassette Awnings

Alpha specifically identifies this motor for two key applications:

Folding-arm awnings

Cassette awnings

This separates it from the WSER50 Universal motors, which Alpha primarily positions for external straight-drop systems.

The Cassette Awning model is specifically configured around the closing behaviour of folding-arm and cassette awning systems.

50Nm Rated Torque

The Alpha WSER50 50/13 Cassette Awning Motor delivers 50Nm of rated torque.

Its output speed is 13 rpm.

Compared with the Alpha WSER50 30/17 Cassette Awning Motor, this model provides greater torque with a slower operating speed:

WSER50 30/17 Cassette → 30Nm / 17 rpm

WSER50 50/13 Cassette → 50Nm / 13 rpm

This provides options for different compatible awning sizes and system requirements.

Correct motor selection should always account for the complete awning installation, including its dimensions, weight, tube configuration and manufacturer requirements.

Built-In Radio Receiver

The motor incorporates a built-in radio receiver, allowing wireless operation using compatible Alpha remote controls.

An external antenna forms part of the motor’s integrated radio system.

Because the receiver is built into the motor, normal compatible radio operation doesn’t require a separate external receiver.

Electronic Limit Switch

The Alpha WSER50 50/13 uses an electronic limit switch.

Its outer stopping position can be electronically programmed, while the inner position can either be determined automatically through resistance detection or manually programmed when required.

Wireless Limit Setting

Alpha specifies wireless limit setting for the motor.

This allows compatible Alpha radio-control equipment to be used when configuring its electronic limits.

For cassette awnings, where the tubular motor is contained within the awning assembly, wireless programming provides a convenient method of configuration without requiring direct access to mechanical limit controls.

Sun/Wind and Motion Sensor Monitoring

Alpha states that this Cassette Awning motor can be used with Sun/Wind Sensors or Motion Sensors.

When connected to a compatible sensor, the motor monitors a regular communication pulse from that sensor.

The sensor issues a pulse approximately every 20 minutes.

If the awning is extended and the motor doesn’t receive the expected signal for approximately 30 minutes, the awning automatically closes.

Alpha explains that the motor assumes the sensor may have failed or its batteries may be flat.

This automatic closure provides an additional protective measure when the motor can no longer confirm that the connected sensor is functioning correctly.

45mm Tubular Motor

The Alpha WSER50 50/13 Cassette Awning Motor uses a 45mm diameter tubular motor body.

It measures 600mm in total length and has a net weight of approximately 2.65kg.

Alpha specifies an IP44 protection rating and an unlimited electronic turn specification.

The motor includes the A2409 C&D and A3415 motor plate.

Compatible Accessories

Based strictly on the information Alpha supplied for this model, we can state compatibility with:

Alpha Sun/Wind Sensors

Alpha Motion Sensors

I wouldn’t name individual sensor models here unless Alpha confirms them for this specific cassette motor. That’s safer than assuming the RS001/RS002 compatibility from the Universal WSER50 range applies identically here.

Electrical Installation

The Alpha WSER50 50/13 Cassette Awning Motor operates at 240V mains voltage.

Electrical installation must comply with applicable Australian electrical requirements and be completed by appropriately licensed personnel where required.

FAQs

What is the Alpha WSER50 50/13 Cassette Awning Motor designed for?

Alpha specifically identifies this motor for folding-arm and cassette awnings.

How does the automatic inner limit work?

The outer limit is manually programmed. When the awning closes for the first time, the motor detects resistance at the fully closed position and establishes its inner stopping position.

Can the inner limit be set manually?

Yes. The inner limit can be manually programmed if automatic resistance-based limit detection isn’t required.

What resistance settings are available?

The standard setting is 25% increased resistance, with 50%, 75% and 100% settings available when additional closing resistance is required.

How powerful is the Alpha WSER50 50/13 Cassette Awning Motor?

It provides 50Nm of rated torque and operates at 13 rpm.

Does it have a built-in receiver?

Yes. The motor incorporates a built-in radio receiver and external antenna for compatible remote-control operation.

What happens if a connected sensor stops communicating?

Alpha states that compatible sensors issue a pulse approximately every 20 minutes. If the awning is extended and no signal is received for around 30 minutes, the motor automatically closes the awning as a protective measure.
