Product Description:

The 55NM82-200-2 servomotor has a frame size of 55 mm (millimeters) and a stroke length of 200 mm (millimeters). It has adjustable pneumatic end-of-stroke cushioning and works in temperatures between -20° C and +80° C. It comes from the Low Inertia PMDC Servomotors series made by Pacific Scientific and has strong aluminum alloy or steel end caps for long-lasting use. The 55NM82-200-2 from Pacific Scientific acts as a highly-efficient motor from the renowned 55NM class.

It is intended for tough industrial tasks that require very fast positioning & accurate incremental motion control. The torque-constant, which is medium in nature, winding available on this module comes with a rated power of 23.2 A and an assessed voltage rating of 48 V. The rotor comes with an air intake and outtake system with baffles that help cool it down by making sure that air flows freely and heat is released even when the motor is running all the time.

The Alnico V-7 magnet material employed gives the motor robust and steady magnetic performance, which helps it work reliably and consistently over time. The 55NM82-200-2 does not come with any analogue tachometer. Furthermore, it does not include any optical encoder built in. The shaft measurement of the diameter at the drive-end attached bearing journal sits between 0.469 to 0.531 inches. This means that it can work with a lot of different couplings and mechanical assemblies. The Pacific Scientific 55NM82-200-2 servomotor is a great option for sophisticated motion control applications where speed, precision, and durability are important since it is well-built, works reliably, and can be adapted to different situations.
