How the Modern SER Drive boosts grinding performance

CSE Uniserve’s Modern SER Drive offers robust mill control, lower energy use and higher power ratings than other mill drive technologies. It is the only mill controller with the ability to offer 100 per cent motor torque at hyper-synchronous speeds for single or dual motor mills up to 22MW, an exclusive benefit no other technology can match.

TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

2021-2-17  Motor The GMD is a drive system without any gear where the transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor. The concept to drive the mill this way is relatively simple using the mill body as motor rotor and mounting the poles there.
