YYGL45SD is selected when the opening width or tube space cannot accept a standard-length 45mm motor. The original page identifies 345mm and 370mm total length variants.

Quick Decision Table
Best For
- Narrow roller shutters
- Compact shading systems
- Projects with limited installation width

Dimension and Installation Information
Confirm minimum installation width by selected version. Check motor overall length, head dimension, tube insertion depth and end cap space. Share bracket-to-bracket distance and tube drawing before sample order.

Tube, Crown, Drive Wheel and Bracket Compatibility
| Item | Compatibility check |
|---|---|
| Tube | Confirm tube diameter, inner shape and wall thickness before sample order. |
| Crown | Match crown profile to tube shape. Do not assume one crown fits all tubes. |
| Drive wheel | Confirm torque transmission, drive wheel profile and tube insertion depth. |
| Bracket | Check head style, fixing holes, load direction and manual crank access when applicable. |
| Accessories | Request a tube and bracket compatibility sheet for OEM projects. |

Short Body Design for Limited Width
YYGL45SD is designed for projects where installation width is limited and a standard 45mm motor body may be too long. Minimum installation width should be confirmed by selected torque version and accessory configuration.
For control and limit selection, compare the project requirement with the limit systems guide and request wiring or programming instructions before bulk order.
Recommended Applications and Selection Notes
Narrow roller shutters
Confirm load, tube, accessory and control configuration before order.
Compact roller blinds or screens
Confirm load, tube, accessory and control configuration before order.
Replacement projects where body length is the main constraint
Confirm load, tube, accessory and control configuration before order.
OEM systems requiring shorter 45mm drive units
Confirm load, tube, accessory and control configuration before order.
Torque, Power and System Selection Guidance
Correct selection depends on curtain size, fabric or shutter weight, tube diameter, friction, wind exposure, duty cycle and the required safety margin. If torque is uncertain, use the torque calculation guide and ask Walter Motor to check the model before sample order.
OEM / ODM Options
Electrical configuration
Voltage, frequency, cable length, plug and wiring requirement should be confirmed by market and order quantity.
Branding and packaging
OEM label, carton, manual, accessory kit and packing method can be discussed by project requirement.
Accessory matching
Crowns, drive wheels, brackets, transmitters, crank parts or charging accessories can be matched by exact system.
Quality Control for This Series
Walter Motor production control can include incoming material checks, assembly process inspection, final performance inspection and aging test according to model and order requirement. For factory process details, see Walter Motor production process.
Certifications and Compliance
Walter Motor can provide certification documents according to model and destination market requirements. Commonly requested documents include CE, LVD, EMC, RoHS and related test reports. Certificate coverage should be confirmed by exact model, voltage, control system and market before order confirmation.
For receiver, remote-control or smart-control models, radio compliance requirements should be confirmed by destination market.

FAQ
What does short body design mean?
It means the motor body is shorter than a standard 45mm model, helping fit narrow openings or limited tube space.
When should I choose YYGL45SD instead of YYGL45S?
Choose YYGL45SD when standard 45mm motor length is too long for the available installation width.
Is YYGL45SD suitable for narrow roller shutters?
Yes, that is the main application, provided torque and accessory compatibility are confirmed.
Does YYGL45SD have the same torque range as standard 45mm motors?
No. The original page lists 10Nm versions. Confirm higher torque needs before selection.
Can YYGL45SD support remote control or electronic limit?
Only if the exact version supports it. Ask Walter Motor to confirm the selected control configuration.
What installation dimensions should I provide?
Provide tube type, tube length, bracket distance, end cap space, cable outlet position and required motor length.
Can Walter Motor check compatibility before sample order?
Yes. Share the tube drawing and installation dimensions for a compatibility check.
Can OEM label and packaging be customized?
Yes. Private label, packaging and accessory kit options can be configured for OEM orders.
