wherein the output shaft further includes a second connector, separate from the first connector, configured to engage with a rolling shaft of a non-roller blind.
2. The motor assembly according to claim 1 , wherein the second connector is arranged at an end of the output shaft, opposite to the rotary electric motor.
3. The motor assembly according to claim 1 , wherein the second connector comprises a cavity for receiving an end of the rolling shaft of the non-roller blind.
4. The motor assembly according to claim 3 , wherein an axis of the cavity is superimposed on a rotation axis of the output shaft.
5. The motor assembly according to claim 3 , wherein the cavity is a first segment of a hole, the hole comprising, from an outside of the cavity toward an inside of the cavity, said first segment followed by a second segment, the second segment being narrower than the first segment.
6. The motor assembly according to claim 5 , wherein the second segment is frustoconical.
7. The motor assembly of claim 3 , wherein the cavity has a polygonal section.
8. The motor assembly of claim 7 , wherein the cavity has a rectangular section.
9. The motor assembly according to claim 1 , wherein the first connector comprises plural axial edges on which the driving wheel can be supported and immobilized in an axial direction.
10. The motor assembly according to claim 1 , further comprising:
a transmission, configured to react and adapt the torque supplied by the rotary electric motor, said transmission being connected at a first end to said rotary electric motor and at an opposite second end to said output shaft.
11. The motor assembly according to claim 10 , further comprising:
a mechanical connector that couples the rotary electric motor to the transmission a manner that ensures a take-up torque between the rotary electric motor and the transmission.
12. The motor assembly according to claim 11 , wherein the mechanical connector includes at least one indentation that receives a positioning element for a casing that accommodates the motor assembly.
13. The motor assembly according to claim 11 , wherein the mechanical connector includes a first ring on a motor side of the mechanical connector and a second ring on a transmission side of the mechanical connector that are axially offset relative to one another.
14. The motor assembly according to claim 13 ,
wherein the mechanical connector includes at least one indentation that receives a positioning element for a casing that accommodates the motor assembly, and
wherein the first and second rings delimit the at least one indentation between them.
15. The motor assembly according to claim 13 , wherein the second ring is provided with at least one stud for fastening the mechanical connector to the transmission.
16. The motor assembly according to claim 9 , wherein the first connector comprises four axial edges.
