Product Description:

For applications requiring exceptional performance, Pacific Scientific offers the M22NRFA-LNN-NS-00 motor. Reliability in operation is guaranteed by its durable structure and advanced manufacturing. Because of its standard rotor type and ability to consistently provide a single smooth shaft configuration, this motor is ideal for incorporation into a wide range of motion control systems.

The M22NRFA-LNN-NS-00 motor has a standard design with eight flying lead connectors that allow for a variety of wiring options. Efficient current management is enhanced by its 6.08 phase resistance and type A winding. Operating with a consistent magnetic field response is guaranteed by the 0.7 mH phase inductance. An efficient dissipation of heat is supported by the 4.5-watt thermal resistance. The rotor inertia is 0.0036 oz-in, in size that allows for precise control of the speed. Applications requiring simple mechanical integration are ideal for this shaft layout that consists of a single shaft with smooth changes. The motor's 2.5-pound weight provides a solid balance between long-term durability and convenience to operate during setup. Reliable mechanical stability is ensured by the shaft's loading capability, that includes axial loads of 13 lb (58 N) and radial loads of 20 lb (89 N).

The M22NRFA-LNN-NS-00 motor boasts rotor inertia and phase inductance that work together to improve performance in dynamic settings. Rotor inertia of 0.0036 oz-in allows for smooth rotational movements, while electrical noise is minimized by the 0.7 mH phase inductance. These specifications are essential for dependable and precise industrial automation. Motor performance remains unaffected by mechanical stresses thanks to shaft loading capabilities. With its reliable functioning and strong mechanical construction, the M22 motor is designed to fulfill rigorous performance standards. It is a reliable option for applications that require precision due to its technological requirements.
