Pittman Elcom SL slotless brushless DC servomotors and gearmotors feature a slotless stator design to eliminate magnetic cogging for smooth and quiet motion, high performance, and long life.
Applications include imaging and medical diagnostic devices, computer peripherals, semiconductor equipment, and many others.
The slotless construction and unique design of Elcom SL three-phase, four-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 minimises 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 speeds up to 8000rev/min.
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 customisation with components to satisfy particular application requirements.
