Pittman Size 8 high-performance slotless brushless DC motors
have been introduced in autoclavable versions to power medical instruments,
dental drills, and other small medical devices. These motors deliver high-speed
capabilities, extended 1,000+ autoclave cycle count, and high efficiency with
low temperature rise to suit handheld operation. Their patented Parallex
winding geometry uniquely enables the motors to develop more power using less
energy.
The DC motors provide compact solutions for tight design
envelopes. They are offered in two standard lengths—2.1 in./53 mm and 2.9 in./74
mm—with diameters of 0.8 in./20 mm. They can realize speeds up to 19,400 RPM
under varying loads, depending on model, and can achieve continuous torque
ratings approaching 4.0 oz-in.
Standard features include precision shielded and replaceable
ABEC ball bearings, high-energy rare earth magnets for enhanced performance,
robust construction with stainless steel housings for durability and
corrosion-resistance, balanced 4-pole rotors for smooth and quiet operation, 3-phase
stator, and Hall sensors.
