AC adjustable speed motor drive systems are the preferred technology for new rolling mill installations and modernization projects. TMEIC designs and manufactures two types of AC solutions for this purpose. Salient pole synchronous motors that meet the high power and torque demands of a hot strip mill, as well as roughing and finishing stands.
The use of variable-frequency drives to run the motors employed in the cement manufacturing process significantly reduces energy consumption and allows each phase to be controlled precisely. Variable-speed drives give us separate, independent control over the flow rates of each motor, which increases their services life and saves on maintenance.

Sep 20, 2017· I conteplating purchasing an smv sensorless vector drive (ESV152N02YXB) and I am installing it on a 2 hp mill. The motor is a Marathon BlueMax (NVD145THTN8029ABP)(FLA 6, 230v, 5400RPM max, 1750 rpm @60hz). It is my understanding that this motor is designed specifically for vector drives. in the settings, do I set the P300 setting to? 4 or 5?
Drives for the Finish Mill Variable Frequency Drives in the Cement Industry Controlling fan fl ow by adjusting speed avoids wasting energy in adjustable dampers and louvers. When large fl ows are involved and the motor energy consumption is signifi cant, varying the speed is the answer. With large
With the Speed Change Handwheel, run the head down to its slowest speed. This action will open the Variable Speed Pulley on the motor to its maximum. DISCONNECT THE POWER Step 2. Directly under the motor is the Motor Pulley Cover which is held in place with three, 10/32 x ¾" socket head cap screws. Take all three screws out and remove the cover.
Mill HP is proportional to the 2.6 power* of the internal mill diameter (inside shell liners) provided the percentage of critical speed is the same. The table, right, gives the 2.6 power of most frequently' used mill diameters. For practical purposes, HP is proportional to speed. This applies to a specific mill, over small changes in speed.
The variable speed drives are electrically located at the motor, which acts as a power factor correction capacitor to the distribution system. The control strategies will be better for the motor drives as they are crucial and consume a significant portion of power in the cement manufacturing industry [ 1 ].
6 | ABB drives in cement Benefits of variable speed drives Controlling processes with variable speed drives has a direct impact on a company's operating costs. Fixed versus variable speed control The most common flow control method is by means of a fixed speed motor where the flow is adjusted by a mechanical device.
