General Description Bi–directional DC linear motor consisting of a moving wound bobbin assembly and a
stationary magnet assembly. (Refer to catalog BR1800 for motor specifications, if your
motor is custom; refer to documentation included with shipment or contact Baldor).

Your motor may or may not be supplied with a mounting flange or other mounting
provisions refer to catalog BR1800 for standard motor specifications or refer to
