There are many situations where astandard three-phase motor is notsuitable for modern drive applica-tions, with requirements such asspeed control and positioning.Where exceptional characteristicsare demanded for arduous applica-tions e.g.; high efficiency, low noiseand maintenance-free drives thenew V motor range from FLENDERATB-Loher has the answers.These motors are specificallydesigned for variable speed opera-tion with maximised thermal andmechanical reserves, all within amodular construction in order tomatch specific drive applications. V range motors are ideal for:֖ Optimizing existing...

Modern and highly sophisticatedmachine tools, such as milling-machines, lathes and CNC work-centres have to operate preciselyand reliably. The ability to controlthe position of the main spindle istaken for granted. There is also agrowing demand for drives with awide speed range and highabsolute speeds in other branches,such as the paper industry, textile in-dustry, transport, storage and test-bench technology, as well as incompanies which are involved in producing complete machinery.Now is the time to replace thedisadvantages of brush-equippedDC drives with the advantages ofmodern...

Enclos-ure Scope of protectionProtection against accidental contact andpenetration of impurities Protection against water Motor design Explanation IP 54Complete protection against contact with partscarrying voltage or internal moving parts. Pro-tection against dust deposits which could causedamage. Penetration of dust is not completelyprevented, but the amount of dust entering themachine will have no effect on the ability of nor-mal motor operation Water sprayed against the ma-chine from any direction hasno detrimental effects Standard de-sign for force-ventilated motors The motors can be...

Output and frequency erally, sensors with PTC characteris-tics will be used. Output, torque and speed range atinverter operation In principle, the speed / output curveand speed / torque curve of a three-phase induction motor atinverter operation can be dividedinto three ranges. The outputs indicated for V and KUVrange motors in the data tables referto continuous operation, duty cycleS1, at rated voltage of 400 V and rat-ed frequency of 50 Hz. Insulation / thermal class The motors of V and KUV range areequipped with an improved insula-tion, comprising reinforced slotliners and double...

Of the three available alternatives forchanging the speed of a three-phase asynchronous motor, the besttechnical method is to change supplyfrequency as opposed to polechanging or slip control. U/f speed control > tional rate of the frequency value, de-pending on actual load condition ofmotor operation, stalling can beavoided (I x R-compensation). Therated motor voltage is reached at rat-ed frequency. If the frequency is in-creased beyond the value of ratedfrequency level, the voltage cannotbe increased proportionately, as itcannot exceed the constant ratedlevel. The magnetic flux then...
