Pittman slotless brushless Ametek Technical & Industrial Products . These motors are said to fit data storage, medical/biotech, semiconductor processing, and automation industries, among other applications.
The company lists additional benefits as precise control due to low inductance and high current bandwidth, especially during rapid acceleration in demanding incremental motion applications; efficient operation at high speeds resulting from a large magnetic air gap that minimizes viscous torque losses; and high thermal efficiency and transient load capacity consistent with excellent winding heat transfer.
The motors (Series 3400, 4400, and 5400) are available in three frame sizes (NEMA 14, 17, and 23) and incorporate 3-phase slotless stators, 4-pole rotors, and neodymium magnets. Depending on model, they are said to achieve maximum continuous torque of 43 oz-in and speeds in excess of 5,600 rpm.
Other features listed include shielded ball bearings, precision-ground hardened stainless steel shafts, and rugged construction. Modular design accommodates customization with components to meet particular application requirements. Options include planetary gearboxes, optical encoders, and brakes.
