PITTMAN® Offers a Full Range of DC Micromotors Specially Designed for Medical Applications

HARLEYSVILLE, PA - PITTMAN® Motors, a division of AMETEK/Precision Motion Control, offers high-performance slotless brushless DC motors for medical applications, such as high-speed surgical tools, dental tools, medical instruments, and other small medical devices.

As the medical industry trends away from pneumatic devices and moves toward DC motor platforms, motor design and manufacturing requires a new level of technology to meet demanding medical applications.

In addition to their small size, PITTMAN high-performance slottless brushless motor designs offer many benefits that are well suited for medical applications. These miniature motors are capable of very high speeds, produce little or no EMI emission (electromagnetic interference), provide long life, and have low audible noise.
In addition, the slotless design eliminates magnetic cogging. In PITTMAN slottless brushless 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 fast response rates.

PITTMAN's smallest high-performance motor is 0.375" (9.53mm) with a maximum speed of up to 70,000 RPM and a torque rating of up to 0.3 oz-in (0.002Nm). Overall length is 2.00" (50.8mm). The motor has a 2 pole permanent magnet rotor, a 3 phase stator and sensorless commutation.

Larger diameters in the high-performance line include 0.5" (12.7mm), 0.8" (20mm), and 1.1" (28mm). Maximum speeds are available up to 60,000 RPM and torque ratings from 0.9 oz-in (0.006Nm) to 14.9 oz-in (0.105Nm). Each diameter has 2 available stack lengths.

The motors are constructed using 4 pole rotors, 3 phase stators, and integral hall sensor feedback spaced for 120 electrical degrees.

Standard features for the high-performance DC motor offering include shielded ball bearings, stainless steel construction and high-energy neodymium rotor magnets. Permanent magnet rotors are balanced for smooth and quiet operation at high speeds. Autoclavable versions are available in all motor sizes.
