High-speed brushless/slotless DC micromotors for medical devicesMclennan Servo Supplies is offering complete sales support for the PITMANN range of specialist high-speed brushless/slotless DC micromotors. With speeds up to 70,000rpm, motor diameters from less than 10mm and excellent torque-to-size performance, the range is aimed at demanding medical device applications and other miniature power transmission systems where very high rotary speeds and compact size characteristics need to be combined with smooth velocity control, low audible noise, long life and high reliability.

The 12 and 24V DC motors are being used increasingly as the medical industry moves away from pneumatically driven devices towards miniature electromechanical systems that require more precise control for the next generation of surgical, dentistry and microsurgery tools. The PITTMAN high-speed slottless/brushless motor construction effectively eliminates the stator teeth by forming and encapsulating the entire stator winding along the inside surface of the back iron. The design entirely removes magnetic cogging, resulting in zero detent torque, low inductance and fast response rates that ensure very rapid acceleration/deceleration and excellent speed regulation.

Motor diameters are from 9.5mm to 28mm and torque ratings from 0.2Ncm to 10.5Ncm, with a choice of stack lengths in five frames sizes for application sizing flexibility. Standard features 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.

The PITTMAN high-speed brushless/slotless DC micromotor range complements McLennan’s product range which includes brushed and brushless DC and AC servo motors, stepper motors, spur and planetary gearboxes, drives and motion controls as well as precision motion control based mechatronics assemblies that are custom designed.
