Slotless Brushless DC Motor features 0.5 in. dia package.

Press Release Summary:




Capable of no-load speeds up to 60,000 rpm and rated for continuous output torque up to 0.9 oz-in., BI-05 Series has slotless design that eliminates magnetic cogging issues. Stator teeth are completely eliminated by forming and encapsulating entire stator winding along inside surface of back iron, resulting in zero detent torque. Overall motor construction is of 17-4, 300, and 400 series stainless steels, and 4-pole rotor is built using high-energy neodymium magnets.

PITTMAN® Introduces BI-05 Series Slotless Brushless DC Motor – High Performance in a 0.5” Diameter Package



HARLEYSVILLE, PA - PITTMAN® Motors, a business unit of AMETEK Precision Motion Control, has introduced its latest offering in a broad range of DC brush and brushless motors.  The BI-05 Series slotless brushless DC motor is designed for maximum precision and performance in a package size perfectly suited for precision equipment such as surgical and dental tools, medical instruments and other health care devices in which small component size is crucial.



As medical procedures trend away from the use of pneumatic devices and move toward DC motor platforms, motor design and manufacturing requires an elevated level of technology to meet the demands of these applications.  The BI-05 was developed with stringent design criteria as the focal point. Its slotless motor design eliminates the magnetic cogging typically found in conventionally wound “slotted” brushless DC motors. The stator teeth are completely eliminated by forming and encapsulating the entire stator winding along the inside surface of the back iron.  The result is zero detent torque, low inductance and extremely fast response rates.



The BI-05 motor body measures a compact 0.5-in (12.7mm) in diameter and is capable of no-load speeds of up to 60,000 RPM. The miniature motor is rated for a continuous output torque rating of up to 0.9 oz-in (0.0064Nm). The overall motor construction is a combination of 17-4, 300, and 400 series stainless steels, the 4-pole rotor is built using high-energy neodymium magnets, and an internal circuit board supports hall sensor feedback spaced at 120 electrical degrees.



Other standard features include shielded ball bearings and a tight rotor balancing spec for smooth and quiet operation at high speeds.  An autoclavable version of the BI-05 also is available.  For more information, visit www.Pittman-Motors.com or contact an application engineer at 267-933-2105.
