EADmotors digital linear actuators arebased on modified hybrid stepping motorsthat incorporate an integral nut assemblyand precision lead screw design. They areextremely reliable devices that provide asimple and efficient method of creating alinear positioning system. EADmotorslinear actuators are available in a varietyof sizes from 17 through 42 frame. Theseprecision devices are capable of producinga linear force of up to 700 pounds and res-olution up to 0.000125” per 1.8° step.
Conventional designs feature internal ro-tating nuts made from SAE 660 bearingbronze. The DuraPlus series, available inboth the L1 and L2 frames, features a pre-cision stainless steel shaft with low fric-tion internal nuts made of a variety ofengineered polymers. The DuraPlus se-ries is the latest advance in integrated lin-ear motion yielding both long life andsmooth, quiet operation.
Stepping Motors
For over 25 years, EADmotors has de-signed stepping motors for a wide range ofapplications. EAD stepping motors havebeen used on a variety of products in di-verse applications such as packaging,semiconductor handling and testing, an-tenna positioning, laboratory equipment,and even electric braking systems for rail-way cars. EAD stepping motors areknown throughout the industry for highquality, long life, and unparalleled consis-tency.
Centrifugal Blowers
EADmotors centrifugal blowers areknown for quiet, reliable operation. Madein single, double, and inverted styles, theydeliver up to 600 CFM airflow. The ACblowers have near-constant speed perma-nent split capacitor motors. Brushless DCmodels operate at fixed or variable speed.
Axial Fans
EADmotors manufactures a broad line ofvane axial, tube axial, and axial fans. Theyencompass a wide range of air volumes atlow to relatively high pressures. Designedfor maximum efficiency at minimum in-put, these high-performance fans offer ex-ceptionally long life and reliability. Quiet,smooth-running ball bearings eliminatethe need for maintenance and lubrication.
Synchronous motors run at an exact speed.The speed will not vary with load or volt-age. We make hysteresis and reluctancetypes in a wide range of frame sizes. EADhysteresis-synchronous motors developsmooth, constant starting and acceleratingtorques. They synchronize any load withintheir torque rating—regardless of inertia.
EAD reluctance-synchronous motorsfunction at constant speeds—and costvery little more than standard inductionmotors.
Induction Motors
In single and 3-phase models, EAD induc-tion motors are designed for a wide rangeof commercial and military applications.For low starting torque applications, per-manent-split capacitor types offer higherefficiency and a higher power factor thanother designs. Capacitor start and splitphase motors are used when a high start-ing torque is required. EADmotors manu-factures both high and low slip permanentsplit capacitor motors to meet a widerange of application requirements.
Torque Motors
Torque motors are com-monly used where prolongedstalled operation or specialrunning-torque characteris-tics are required. They mayinvolve either static or dy-namic forces.
Applications may requiresmooth, moderate accelerat-ing torque and low speedwith speed ranges from nearsynchronous to zero.
Stator/Rotor Sets
EADmotors provides frameless versionsof all of our designs. Stator/rotor sets offerthe advantage of eliminating componentparts in a system such as redundant bear-ings and couplings. They also allow sys-tems to be smaller and more reliable aspossible failure modes are eliminated atthe design stage. Contact us for more in-formation about how stator/rotor sets canmake your products more competitive.
EADmotors offers a line of small, custom designed brushless DC motors for demandingapplications. EADmotors has built a reputation for supplying the highest quality minia-ture brushless DC motors available. These motors are custom designed on an applicationspecific basis to meet the most demanding application requirements.
Lightweight aluminum housings and high energy rare earth magnets make these motorsideal for aircraft applications. Modified designs with stainless steel housings are idealfor medical, laboratory, and surgical applications.
