Product Description:

The 55NM81-100-2 is a steel servomotor coupling with a jaw coupling type and a torque rating of 100 Nm (Hundred). Manufactured by Pacific Scientific as part of their Low Inertia PMDC Servomotors series, it features a bore diameter of 55 mm (millimeters) and weighs 2.3 kg (kilograms). The coupling operates within -20° C to 80° C (4° F to 176° F or 253.15 K to 353.15 K) and complies with RoHS standards. The 55NM81-100-2 produced by Pacific Scientific is a versatile motor from the popular 55NM lineup. The 55NM81-100-2 was engineered to provide instant positioning. Furthermore, this motor was designed to provide accurate management of incremental movement. This module has a torque-constant (medium) winding. This medium winding gives this rotor a rated power of 19.2 Amperes. This steel servo comes with a voltage rating of 42 Volts. Because of these capabilities, the motor may be used in tough situations where quick and precise motions are necessary. The rotor comes with an air design that lets air come inside and flow outside smoothly without baffles that helps cool it down by letting air flow freely and letting heat escape while it is running. This type uses Alnico V as the magnet material. This is a good option for keeping the motor's core magnetic fields strong and steady. This motor does not come with any analogue tachometer. Moreover, users will also find an optical encoder absent from this steel servo. This gives the users a great sense of flexibility as they can choose a suitable feedback devices that caters to their special needs. The NM product line includes the 55NM81-100-2. This series is noted for its strong construction and ability to handle high-speed, high-precision motion control demands in industrial automation settings.
