Becker XL60 /4G	60Nm	Standard residential pools Dimensions up to 4.5×10m	• 24V power supply • Speed 4 rpm • Obstacle detection • Electronic limit switches	See product
Becker XL120 /3G	120Nm	Large residential pools Semi-collective pools Dimensions 5×15m to 6×12m	• 24V power supply • Speed 3 rpm • Integrated thermal protection • Progressive torque ramp	S ee product
Becker XL200 /3G	200Nm	Collective installations Professional use Dimensions up to 7.5×20m	• 24V power supply • Speed 3 rpm • 150kg load capacity • Maximum performance	See product

2. Calculation method for required torque (Nm)

Using the sizing chart

The Becker chart allows you to evaluate the required torque based on the pool dimensions. How to use:

Locate your pool length on the vertical axis (2m to 8m)
Identify the width on the horizontal axis (2m to 20m)
The intersection indicates the recommended torque in Nm

⚠️ Warning: Areas located beyond the red line correspond to loads exceeding the maximum limit authorized by Becker (150 kg).

Motor torque calculation parameters

The sizing of the Becker XL pool motor depends on several critical factors:

Main criteria:

Pool surface area (length × width)
Specific weight of the slats
Slat thickness
Winding shaft diameter
Hydraulic resistance (increase of approximately 20%)

Example of sizing a Becker motor for a 5x10m pool

Practical case: 5m × 10m pool

According to the chart: required torque ≈ 42-45 Nm
Recommended motor: XL60/4G with 60 Nm of torque

Pricing of Becker XL60, Becker XL120 and Becker XL200 motors

Prices vary mainly according to the power of the motor. Investing in a model slightly higher than the minimum requirements generally proves to be wise.

Indicative price ranges:

Becker XL60 motor at 60 Nm (XL60-M06 24V): between €600 and €825
Becker XL120 motor at 120 Nm (XL120-M06 24V): between €800 and €990
Becker XL200 motor at 200 Nm (XL200-M06 24V): from €990

Frequently asked questions about Becker pool motors

What risks does an undersized motor present?

An insufficiently powerful motor causes accelerated wear, risks of jamming, excessive energy consumption and can lead to complete system failure.

Why is the 120Nm motor particularly popular?

The Becker XL120/3G perfectly combines power and durability. Its torque reserve allows it to overcome difficult conditions (debris, algae growth) while maintaining reliable operation over time. Its reduced speed (3 rpm) limits mechanical wear and extends service life.

Can a Becker shutter be motorized with a remote control?

Indeed, the addition of a radio receiver compatible with DC power allows for remote control. This installation must imperatively be entrusted to a qualified professional. French regulations require the maintenance of the manual key unlocking system, even after installing a radio control, in accordance with the NF P 90-308 standard.

What influence does the shaft diameter have?

The shaft diameter (133 mm as standard) directly impacts the required torque. A larger diameter shaft generally requires higher torque.

Are Becker motors universally compatible?

Becker motors offer wide compatibility, but the suitability of the fastening systems and the shaft diameter for your installation should be checked.

Main compatible roller brands: Walter, Maytronics (Aqualife), DEL, Abriblue, Fluidra (AstralPool), T&A, Ocea, Covrex, PoolTechnologie, Aquacomet.

Point of caution: Systematically check the shaft diameter (generally 58mm for Becker tubular motors) and the fastening system specific to your pool cover model.
