BEI Kimco Magnetics
Motion Control Products for Aerospace & Defense
is a pioneer in the development of direct-drive, or "Frameless", torque motors (torquers). These compact, high performance motor part-sets use high slot-to-pole ratios and couple the motor's rotor directly to the load, without the need for gearing. This approach eliminates errors due to mechanical friction/backlash and is ideally suited for applications where rapid starts/stops, high acceleration and low speed precision motion are required. The brushless versions of this technology are being used... (read more)

Waterproof Step Motors Make Waves in Industry
Because of the preponderance of water and solvents, motion control components are often exposed to the risk of corrosion and failure. Waterproof motors are a key part of the solution to water-induced motor failure problems. Today's waterproof motors are specifically designed to survive a minimum
Reasons for Turning to Slotless DC Motor Technology
and slotted designs is the rotor diameter. Slotless. motors have a larger rotor diameter than slotted construction for the same outside motor diameter and. will generate a higher inertia, as well as accommodating more magnet material for greater torque. For. applications with high-inertia loads
Limited-Angle Torque Motors
A special type of brushless motor is called a limited-angle torquer (LAT). LATs are constrained to produce torque through a rotation angle of less than 180 . But they are widely used to operate servovalves, direct laser mirrors, position missile-guidance radar antennas, open shutters
The Rate Integrating Gyroscope (RIG), Part 1
is a turn about the input axis (IA). The output is a turn about the output axis (OA). The precession of the gimbal takes place only when the rotor is spinning, of course. Conversely, a rotation imparted to the gimbal in its freedom axis (the OA), will cause a torque about the input axis (IA). Gyroscopes
New ways to measure torque

The motor has a hole through its center which accommodates the RF rotary joint, and its rotor directly supports the load of the antenna , so no additional space is required for gears.
Feedback and Control for Everyone
This means that accurate positioning of the rotor of the drive motor implies accurate positioning of the antenna dish provided of course that the structural resonances are not excited.
