Product Description:
Compact and short, the Pacific Scientific S21HNNA-HFVM-00 is a brushless servo motor from the S series that is designed to react accurately and swiftly in confined spaces.
Using standard mounting techniques is possible because it is constructed on a NEMA 23 frame size. It weighs only 1.4 kg, making it suitable for applications requiring mobility or limited space. It is given without lowering torque delivery since it is deemed permissible. The motor stalls at 0.5 Nm in steady conditions, guaranteeing consistent effort performance under continuous load. Its 1.36 Nm maximum working torque gives it the additional capacity to satisfy demands for rapid or fluid movement. This motor's torque constant of 0.2 Nm/ARMS allows it to deliver a consistent torque at different current levels. It operates consistently across a very broad speed range owing to its relatively low voltage constant of 0.13 VRMS/rad/sec. Motors with an internal line inductance of 3.7 mH are used to control dynamic response.
It has a line-to-line resistance of 3.0 ohms to help sustain operational thermal efficiency. Because the motor (in single-stack length form) can accelerate quickly without overshooting and has a rotor inertia of 0.042 x 10⁻³ kg·m², it can be used in systems that need rapid response but precisely defined positioning. A typical commutation Hall sensor plus a secondary 1000-pulse-per-revolution (ppr) encoder with line driver feedback capabilities make up the two-part feedback system. It features an MS-style connector installed on the motor to facilitate simple connection with an electrical system, as well as a Viton shaft seal that protects against impurities. It can be purchased at Wake Industrial with a one-year warranty.
