ELCOM SL® Brushless DC Motors And Gearmotors Feature Slotless Design to Eliminate Magnetic Cogging



HARLEYSVILLE, PA, July 11, 2003 - ELCOM SL® slotless brushless DC servo motors and gearmotors available from Pittman feature a slotless stator design to eliminate magnetic cogging for smooth and quiet motion, high performance, and long life. They are ideal for applications in a wide range of industries, including data storage, medical/biotech, semiconductor, automation, commercial aviation, hobby, and others requiring high performance and reliability.

The slotless construction and unique design of ELCOM SL 3-phase, 4-pole brushless motors and gearmotors yield several other advantages over conventional slotted brushless motor products. Low inductance and high current bandwidth promote precise control, especially during rapid acceleration in demanding incremental motion applications; a large magnetic air gap minimizes viscous torque losses for efficient operation at high speeds; excellent winding heat transfer is provided for high thermal efficiency and transient load capacity; and robust rotor construction allows rotational standard speeds up to 8000 RPM. (Higher speeds available upon request.)

ELCOM SL slotless brushless DC motors and gearmotors are available in three frame sizes (motor Series 3400, 4400, and 5400 and gearmotor Series GM3400, GM4400, and GM5400) with several length and performance options available. All feature a modular design that promotes customization with components to satisfy particular application requirements.

Every Pittman motor is subjected to performance testing prior to shipment.
