11 dc brushless motors (P/N 5A503-1)

The NASA/NSSC is seeking 11 dc brushless motors (P/N 5A503-1) for the Wallops Arc-Second Pointing System to be built in CY 2027 and CY 2028. The motors must meet specific requirements, including a maximum torque of at least 25 ozin continuous when powered at +24VDC, a stall current of no more than 3.5 Amps, and specific shaft and flange dimensions. • The motors must be capable of a maximum torque of at least 25 ozin continuous when powered at +24VDC. • The stall current shall be no more than 3.5 Amps. • The shaft shall be 0.313” with an eared flange. • Maximum length will be less than 3” long. • Maximum diameter will be less than 1.5” in diameter. • The eared flange will be no larger than 1.75” on the diagonal.
