Designed to be pressed into a machine’s housing, the SDP/SI NH1-D series Frameless Brushless Motors provide a compact, lightweight, and powerful motor solution. Available in standard sizes 35 mm, 52 mm, 64 mm, 77 mm, and 100 mm, the frameless motors are machine wound with bondable magnet wire for superior dependability. Each motor features a large inner diameter rotor permitting easy cable management.

“Rated for continuous operation the frameless brushless DC motors are an ideal solution for many applications including the replacement of heavier, traditional motors by eliminating components, reducing torsional losses, decreasing weight, system inertia, and size envelope while providing maximum speed control,” said Jacques Lemire, Business Unit Director, Motors & Motion Control. 

“Offering an assortment of motion control solutions that ensure accuracy and dependability the frameless motors provide an additional option to those in the robotics, industrial automation, and medical industries.”
