Dimension and Installation Information
Use the original YYGL45M dimension drawing for head and body reference. Confirm total length by selected torque version. Check crank access, bracket clearance, tube insertion depth and cable outlet position 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. |

Manual Override and Mechanical Limit Operation
Manual override allows the shutter or awning to be operated by hand crank during power failure. The final manual operation design depends on motor head, crank system, bracket and installation structure. Confirm crank direction, access position and available space before order.
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
Roller shutters with power-failure operation requirement
Confirm load, tube, accessory and control configuration before order.
Outdoor awnings where crank access is practical
Confirm load, tube, accessory and control configuration before order.
Medium-duty shading systems using 45mm tube accessories
Confirm load, tube, accessory and control configuration before order.
OEM projects that need AC wiring and manual backup
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 is the main advantage of YYGL45M?
It adds manual override to a 45mm AC mechanical limit motor, so the system can be operated by crank when power is unavailable.
Can YYGL45M operate during power failure?
Yes, when the correct crank system, bracket and motor head configuration are selected.
What is the difference between YYGL45M and YYGL45S?
YYGL45S is the standard mechanical limit motor. YYGL45M adds manual override for emergency hand operation.
Is YYGL45M suitable for awnings?
It can be used for awnings when torque, bracket, crank access and duty cycle are confirmed.
Does YYGL45M support remote control?
The YYGL45M page data identifies a mechanical limit manual override motor. For receiver control, compare YYGL45R or ask Walter Motor to confirm a matching configuration.
How do I choose the correct torque?
Share shutter size, weight, tube diameter and application. Walter Motor can check the torque and safety margin before sample order.
What information is needed to confirm manual override installation?
Crank access position, motor head direction, bracket style, tube drawing, installation width and emergency operation requirement are needed.
