Kollmorgen (www.kollmorgen.com) unveiled a new family of frameless motors developed from the extensive and proven portfolio of Kollmorgen designs, the new KBM™ Series Frameless Brushless Motors. The new series is available in 14 sizes for high- or low-voltage operations. The series delivers the speed, torque and power within a compact footprint and cost-effective package that provides system designer flexibility in specifying a motor, which fits the dimensional requirements and specific performance of the application.
“Kollmorgen engineers are adept at leveraging existing design successes to develop new motors with superior value, enabling our customers to gain a competitive advantage through faster time to market and minimized investment. KBM motors were born of those efforts,” said Kollmorgen, North America Product Manager Bryan Bird. “OEMs tasked with designing a highly optimized and tightly integrated machine or device will find KBM motors to be an excellent choice due to their unique design which inherently improves mechanical compliance, reduces parts count, and improves performance through the use of powerful direct-coupled electro-magnetics with a light weight and compact form factor.”
The new KBM frameless brushless motors have standard frame sizes between 60mm and 825mm in diameter, and for 480 VAC or 240 VAC operations. The series has additional motor windings to allow optimized performance at lower voltages (“12 or 24 V DC”). Each frame size is available with three or four stack lengths. They feature encapsulated stator windings for environmental and thermal performance. Its internal windings are well rated for continuous duty operation up to 311°F (“155°C”), enabling reliable performance even under extreme temperature and duty conditions. The rare-earth neodymium Iron Boron magnets give continuous torque ranging from 1.07 lb-ft (1.45 N-m) up to 2540 lb-ft (3445 N-m), and peak torque ranging from 3.62 lb-ft (4.91 N-m) up to 9450 lb-ft (12,812 N-m), for maximum power ranging from 1.22 HP (550 W) up to 24.8 HP (18.5 KW) within the smallest motor package.
