BOF16 Outside Rotor Brushless DC Motors

FRACTIONAL HORSEPOWER MOTORS

Outside Brushless DC Motors

Quiet, Brushless Motors

BOF16 outside rotor brushless DC motors provide smooth, efficient operation at high speeds. The brushless design ensures low audible noise and long life. Utilizing bonded ferrite magnets, these brushless motors provide excellent performance and value demonstrated by their low cost to high torque ratio. They are available in two lengths with a variety of options, including custom windings to achieve different speed / torque operating points, electronic drives, encoders and Hall effect or sensorless feedback.

In some applications, motors with an outside rotor enjoy several advantages over their counterparts with inside rotors. Motors with outside rotors perform especially well in applications with significant torque oscillation. Also, BOF outside rotor motors have relatively low profile dimensions for height so they can easily fit in an envelope that is wider than it is tall - such as medical equipment or industrial machines.

We’ve designed thousands of DC motors, so if our BOF series doesn’t meet your needs,  contact us to talk about your specifications. One of our other designs may meet your needs, or our engineering department can design a motor to meet your specific requirement.
