Good speed (ratio) stability Good ratio and following controlCrammer/5-30 FeederA device used to cram material into theextruder throat, rather than use a gravityfeed. TENV enclosure required because of the dusty environment Good low speed torque Needs torque control (torque limited, speed controlled), PVC manufacturingPullers2-15A set of friction rollers used to pull material out of anextruder die at a precise rate, to assure constant cross-sectional dimension.

3 The wall thickness can becontrolled or changed by pulling at precise rates. TENV enclosure Accurate ratio controlFilm with a film die, either circular (blown film) orflat (cast film) and appropriate downstream equipment. TENV enclosure Accurate ratio controlBlow Molding 20-250 Blow molding takes an extruded hollow piece of plasticmaterial, called a parison, then closes a mold around itand injects air into it to blow the material into theshape of the mold. Used to produce hollow shapes. High torque Continuous operation High efficiencyInjection 2-100 MoldingInjection molding injects the plastic materialdirectly into a mold under high pressure, without blowing it.

4 Used to produce solid shapes. The extruder on an injection molding press istypically hydraulic, due to the pressures used, butother drives need to have the position control and fastresponse and cycle times of a servo-type auger that also accomplishes shear heating andmixing of thermo-plastic material.

9 Performance characteristics can be customized forspecific CURVES Figure 1 shows a TYPICAL torque/speed curve, along with itsrated torque, speed, and current parameters, from the"Performance Curves" section of this selection guide. Thecurves represent TYPICAL motor performance when driven by abrushless motor drive with a 640V dc bus, a sinusoidal currentoutput, and continuous and peak current capabilities to matchthe motor ratings in the table. Note that the curve shows bothcontinuous and intermittent duty areas of 1: E184E1 DPBV performance curve and tableFigure 1 CONTINUOUS DUTY AREAThe motor may be operated at any speed and torque withinthe continuous duty area for any length of time.

10 The area isbordered by the continuous torque output line and themaximum speed continuous torque line represents the maximum torquethe motor can produce continuously at different speedswithout exceeding the rated winding temperature of 140 C in a40 C ambient (See "Ambient Temperature Derating", page70). It is a function of the motor s maximum speed line represents the maximum speedthe motor can reach at different loads. It is a function of thebus voltage of the drive (640V dc for these curves) and themotor winding. Different windings may produce highermaximum speeds, but at the expense of higher currentrequired to produce a given DUTY AREAThe motor may be operated at any speed and torque withinthe intermittent duty area for shorter lengths of time.
