Custom Direct Drive Brushless DC Frameless Torque Motors

Moog has a variety of custom design options for frameless (pancake) motors. For example, winding designs to modify torque sensitivity, back EMF, DC resistance and inductance in the event a power source (voltage or current) is limited. Stack lengths can be varied (from 0.10 to 20.0 inches depending on the model) for tailored performance.  For ease of installation, mounting flanges, hubs, mounting holes and connectors can be added.
