Dc servomotors

The 8540 Series dc servomotors feature improved power density through the use of bonded neodymium magnets. The units have approximately twice the continuous torque rating of previous motors. The motors measure 1.18 in. (30 mm) in diameter and come in three lengths — 2.114 in. (53.69 mm), 2.585 in. (65.66 mm), and 3.057 in. (77.65 mm). Depending on the model, continuous torque ratings range from 2.5 to 8.3 oz-in. (0.018 to 0.059 Nm) without the use of a heat sink.

The motors are available with eight standard windings ranging from 9.55 to 48 V and have standard preloaded ball bearings that allow for high speeds, radial and axial-shaft loading, and higher temperatures.
