Introduced in autoclavable versions, Pittman’s “Size 8” slotless brushless DC motors power medical instruments, dental drills, and other small medical devices. They deliver high-speed capabilities, extended 1000+ autoclave cycle count, and high efficiency with low temperature rise to suit handheld operation. Their patented “Parallex” winding geometry enables the motors to develop more power using less energy. The motors are offered in two standard lengths of 53 and 74 mm with diameters of 20 mm. They can realize speeds up to 19,400 rpm under varying loads, depending on model, and can achieve continuous torque ratings approaching 2.8 Ncm. 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. These autoclavable motors additionally can be customized with gearboxes, optical encoders, and drives, among other options, to tailor motor to application.

3D Printing, or Additive Manufacturing, is becoming a game changer in the manufacturing industry. With new hardware, software and materials, one is now able to print complex parts in a huge variety of dimensions. In our focus on 3D Printing, we present an interesting application on the printing of a Turbine Wheel for a clinic in Ethiopia. Another case study describes the printing of Bronchial Grippers . News on the most recent products include a Large Parts Printer , as well as a new material called Unfilled Nylon . This and lots more in the Jan/Feb issue. Enjoy the first IEN Europe in 2014!
