A new family of frameless brushless motors, the KBM Series, comes in 14 sizes for low or high-voltage operation. Frame sizes range from 60 to 825 mm in diameter, and for 240 to 480-Vac operation. Each frame size is available with up to three or four stack lengths and feature fully encapsulated stator windings. Internal windings are rated for continuous-duty operation up to 155°C. Rare-earth neodymium-iron-boron magnets provide high continuous torque ranging from 1.07 to 2,540 lb-ft, and peak torque ranging from 3.62 to 9,450 lb-ft, for maximum power ranging from 1.22 to 24.8 hp. Maximum available speeds are 105 to 18,600 rpm.
