Pittman Motors offers slotless brushless DC motors for medical applications, such as high-speed surgical tools, dental tools, medical instruments, and other small medical devices. These miniature motors are capable of 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 the 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. The smallest 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.
