Pittman® Brushless DC servomotors from PennEngineering® Motion Technologies (Harleysville, PA) feature a slotless stator design for applications in data storage, medical, semiconductor, and automation. Features include low inductance and high current bandwidth for control during rapid acceleration in incremental motion applications, and a large magnetic air gap that minimizes viscous torque losses.
The motors are available in three frame sizes with 3-phase slotless stators and 4-pole rotors with neodymium magnets. Speeds to 8,000 RPM are possible. Peak torques range from 13.3 oz-in to 195 oz-in, depending on model.
