CCVs are used for driving mine hoists, rolling mill main motors, ball mills for ore processing, cement kilns, ship propulsion systems, slip power recovery woundrotor induction motors (, Scherbius drives) and aircraft 400 Hz power generation. The variablefrequency output of a cycloconverter can be reduced essentially to zero.
Synchronous Motors for Driving Steel Rolling Mills Abstract: It is the purpose of this paper briefly to discuss, from a practical standpoint, the application and design of synchronous motors for steelmill mainroll drives, in an effort to show what their advantages and disadvantages are; where they should, ...
It is thus suited to large lowspeed drives, where motors can be made with high polenumber and thus low synchronous speed. The complexity of the drive means that only high power systems (>>1 MW), or specialized applications ( conveyor drives for use in hazardous environments) are economic. They are used on large ball mills, mine winders, etc.

dc motor drive for rolling mill apliion. A DC motor is any of a class of rotary electrical machines that converts direct current electrical The DC motor was the mainstay of electric traction drives on both electric and as toys and disk drives, or in large sizes to operate steel rolling mills and paper This has restricted the practical appliion of this type of motor.
Jul 24, 2017· A synchronous electric motor is an AC motor distinguished by a rotor spinning with coils passing magnets at the same rate as the alternating current and resulting magnetic field which drives it. Another way of saying this is that it has zero slip under usual operating conditions. Contrast this with an induction motor, which must slip in order to produce torque.

The highest vibration is 30mm/sec RMS axial on the motor non drive end bearing.(White metal Bearing) The gear mesh frequency is 4200 CPM. The dominant frequency is 2400 CPM. We can not relate this to anything on the Mill or drive train but with the high energy vibration the number 1 suspect is the 5500 Kw motor but need something to confirm this

Mills and GMDs Maarten van de Vijfeijken* looks at large, larger and the largest units in grinding ore T he gearless motor (also called wraparound motor or ring motor) is a very large synchronous motor. The poles of the motor are directly installed on a pole flange on the mill shell: this means the mill body becomes the rotor. The stator of the
Sep 29, 2008· Ball mills are a good candidate for synchronous motors. They may be over sized and over excited to correct the power factor of acres of small motors on the flotation cells. I worked in one mill that used two 3000hp motors per mill. Direct gear drive with two motors is not a good application for synchronous motors. We used wound rotor induction ...
