Advantages of SER drives for SAG mills | GoHzDec 19, 2014 . The SER drive via a feedback transformer feeds energy back into the power supply. This returned energy is proportional to the speed difference from synchronous speed. So at say 85% speed, 15% of the motor rated power is returned from the rotor to the supply. At a hyper-synchronous speed, the SER.synchronous motor for mill drive advantages,Advantages of low speed drive solutions - PACEDec 10, 2012 . As a result, installation of variable speed motors tends to be easier. Low speed synchronous motors with frequency converter control can generate sufficient torque to start a mill turning without needing an air clutch. This is a major advantage of variable over fixed speed drives, because eliminating the clutch.John Frank
TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS MILL DRIVES FOR GRINDING APPLICATIONS. M. Ahrens, ABB . Picture of a typical GMD system for a SAG mill. Figure 2 presents the power circuit of a cycloconverter fed synchronous motor. The synchronous motor has one 3-phase winding in the stator.
Mar 17, 2017 . Motors considered are the squirrel cage motor, wound rotor motor, and synchronous motor. One important advantage of the synchronous motor is the possible correcting of power factor within your operation, through its use. When using a synchronous motor we recommend having 200% starting torque,.
Abstract -- Synchronous motors continue to be a viable alternative to induction motors because of efficiency advantages. Long used for providing leading kVARs for PF improvement and helping with the device switching in Load. Commutated Inverter (LCI) drives, these machines are efficient prime movers for large Mill.
As we know synchronous machine is a constant speed machine ,the various advantage of synchronous motor is (i)It is used to run the load which need constant speed(like synchronous motor used in . (iv)It is preferred for driving the loads requiring high powers at low speed e.g ball mills ,crushers etc.
Induction motor. Size of indicates quantity of motors. Introduction. AC adjustable-speed motor drive systems have been established as the preferred technology for new rolling mill installations and extensive modernization projects. The AC adjustable-speed motor drive system provides metals mills with many advantages.
