A family of brushless servo motors (from AMETEK) purportedly extends the service life of applications ranging from medical and industrial equipment to instrumentation and automation machinery, among others. These motors (AB23000, AB34000, and AB48000) in NEMA sizes 23 (2.25 in.), 34 (3.54 in.), and 56 (4.75 in.) can provide continuous stall torque from 0.42 Nm to 12.88 Nm (3.75 lb-in to 114 lb-in) and peak torque from 1.28 Nm to 38.3 Nm (11.3 lb-in to 339 lb-in). Rated speeds range from 2800 RPM to 5200 RPM and voltage ratings up to 325 VDC for offline drives can be achieved.
