SLOTLESS BRUSHLESS DC MOTORSWhat is an Elinco slotlessbrushless DC (SBLDC) motor?An Elinco slotless brushless DC (SBLDC) motorconsists of a stator winding positioned inside alaminated stator ring (without conventional teeth)and a permanent magnet motor. This providesmore peripheral space for the stator winding.This also allows more magnet surface area andux. Powerful rare earth magnetsprovide high torque to motor weight ratios. Theabsence of stator teeth enables more copperwinding and power density which can developmore torque. It also eliminates torque coggingand minimizes audible noise.When others say they can't, wesay we can... and do!Whether the issue is speed, power, weight, size,ciency, noise, torque ripple, heat rise, etc.,each or all are optimized to achieve customperformance with relatively short design andresponse time.Tooling charges for custom prototypes arenominal. Elinco has produced a wide range of sizesfrom 1” to over 10” in diameter, and basic toolingof many sizes is already available.Elinco ed OEMdesigns. Bearings, housings and alignmentproblems are eliminated, thus providing cost-We are experts in the designand fabrication of custom SBLDCmotors and rotor/stator sets.Elinco exibility,responsiveness, and expertise in the design andfabrication of custom SBLDC motors. There arefew restrictions on physical dimension choicessince stator laminations are simple annularrings, economical to produce, and high energymagnets are readily available in arcs and slabsof all sizes. There is freedom to choose magneticand mechanical air gaps, number of poles, polespans, back-iron thickness, magnetic densities, andc application.ShaftsHardened Stainless Steel or otherSpecialty Alloys, Precision Gorund,Custom Designed Extensions.BalancingBalancing Washers for PrecisionBalancing to Quality Grade ANSI G-0.4or better.As the energy product of magnets increases andcosts decrease, and the manufacture of the statorective,the slotless motor technology will be the logicalchoice for many brushless DC motor applications.StatorsSlotless with Low Inductance and Lowciencies, andCogless, Jitter Free Operation at both Highand Low Speeds.Housingsgurations and Mounting Means to Suit thec Application.
