Brush DC Servos Minimize Magnetic Cogging

The Pittman Series 14000 brush-commutated dc servomotors employ 11-slot skewed armatures to minimize magnetic cogging, a.k.a. reluctance torque. The components suit a range of power applications for computer peripherals, medical and imaging equipment, and automation systems. Other standard features include two-pole stators, sintered bronze bearings, ceramic magnets, copper graphite brushes, silicon steel laminations, diamond-turned commutators, and heavy-gauge steel housings. The motors are available in seven lengths and achieve peak torques up to 420 oz.-in. and maximum continuous torques up to 50 oz.-in. at speeds up to 3,930 rpm depending on model. Speed, voltage, current, and torque characteristics are variable to meet application requirements. AMETEK TECHNICAL & INDUSTRIAL PRODUCTS, Kent, OH. (877) 748-8626.
