The nomenclature "radio motors" is acceptable. It refers to roller shutter drives with a built-in controller and radio receiver.

I will disagree with you...
Perhaps roller shutters are not Ark's your strongest point. .
The issue is quite simple. If there are radio controllers for BFT roller shutters installed somewhere in the boxes , the motors are ordinary (without receiver, with mechanical or electronic limit switches) from any manufacturer. If there are no such modules, the motors are BFT roller shutter drives of the REEL RUA Axx 230V R45 series. (The xx after the letter A stands for the magnitude of the force torque in Newton metres and the value is selected according to the size and therefore the weight of the roller shutter. In BFT, the values are 10Nm up to a maximum of 18kg, 20Nm up to 35kg, 30Nm up to 55kg and 50Nm up to a maximum of 88kg). R45 is R=radius, 45 is the diameter of the motor in mm (i.e. for a shaft from 60mm- mostly octagonal).
