A series of frameless motors has been launched by Stock Drive Products/Sterling Instrument (SDP/SI) as a drop-in solution for robotics applications.

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 of 35 mm, 52 mm, 64 mm, 77 mm and 100 mm, the frameless motors are machine wound with bondable magnet wire for superior Source: SDP/SIdependability. Each motor features a large inner diameter rotor permitting easy cable management.

With their compact size the NH1-D series frameless motors fit easily into smaller machines requiring precision, high efficiency, low inertia and high torque density.

“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.”
