- the processing unit and the drive can be arranged inside a cabinet located near the rewinder.
- An advantage of such a motor or set of direct drive motors is that it makes it possible to avoid the use of any transmission element, such as a reduction gear, and therefore overcomes all the problems generated by such a reducer, such as in particular possible failures and operating clearances of the reducer, as well as the losses that it causes by its efficiency.
- such a motor or set of motors makes it possible to generate shorter torques that are greater than current asynchronous motor technologies, which proves to be important in making it possible to reduce the braking time of the reel when stopped. emergency (at constant engine power) or to pass more quickly above the feed point of the reel, this requiring a strong overtorque, compared to the torque generated in current use, over a short period (typically less at 5 seconds).
- the winder according to the invention benefits from the large dimension of the coil to allow an arrangement of a large number of permanent magnets, and to place said magnets at a significant distance from the X axis, in order to provide the desired torque.
- the spool rotational speed is typically around 30 rpm, but more generally can range from almost zero to 100 rpm.
- the torque produced by the motor can reach 8000 Nm.
