Product Description:

The P21NSXA-LDN-NS-02 Motor from Pacific Scientific is a well-designed motor that was designed to meet the precise requirements of motion control. The NEMA 23 frame size and 2.25-inch planar dimension of this P21 motor provide it with a significant amount of power. Its single-stack design and standardized manufacturing ensure dependability and durability for specialized industrial automation applications.

The P21NSXA-LDN-NS-02 motor features a double-shaft design with shaft adjustments. When turned on in both phases, the motor provides consistent and stable motion control with a holding torque of 77 oz-in. Power efficiency is improved by the rated current per phase of 0.67 A (DC). With an average phase inductance of 23 millihertz and a tolerance of ±10%, the motor's phase resistance of 5.22 Ohms guarantees consistent electrical performance. The heat resistance of the motor, when mounted, is 5.5 °C/Watt that ensures its operational efficiency. In order to ensure the safety and dependability of electrical connections, the receptacle-based connection type delivers. The motor has efficient performance specifications due to its Type A winding and standard rotor type. For applications needing mechanical pliability, the twin shaft extension is a suitable option.

The P21NSXA-LDN-NS-02 motor features a unique configuration that includes non-standard parts and the possibility of a no-feedback encoder. In order to guarantee compatibility with a wide range of system designs, the motor's mounting configuration and type of manufacture fulfill NEMA standards. Electrical and thermal performance is guaranteed to be constant over a wide variety of operating situations by the phase inductance and thermal resistance. This P21 motor is well-suited for incorporation into intricate systems due to its dependable motion control. Reliability in performance and efficiency in operation are guaranteed by its design and technical standards.
