T22NRHJ-LDN-NS-00 Image 1


The T22NRHJ-LDN-NS-00 is a high torque stepper motor in the T Motor Series by Pacific Scientific. Optimized with magnetic components to achieve a compact footprint, it produces more torque than three-phase and five-phase motors while operating at nominal speed. It has a standard leadwire hookup construction style and can function more economically than servo motors. The motor's key features include better torque linearity beyond rated current, smooth microstepping performance, and negligible detent harmonic torque. Despite its power, this two-phase stepper motor uses less input power compared to its counterparts and can be mounted in NEMA 23 style. It is encased in a rugged, 2.25-inch frame making it suitable for challenging environments. It includes a removable cover for easy access to the leadwires when necessary. A laminated rotor and a smooth shaft with a rear shaft extension make up this motor's internals. Its connections consist of four parallel-connected leads. The motor has specifications of 1.98Nm holding torque, 0.0424Nm detent torque, 3.69C/Watt thermal resistance, and 0.0408kgm2 x 10-3 rotor inertia. Its compact size is just 3.06 inches, weighing a mere 2.3kg. The T22NRHJ-LDN-NS-00 also includes a 0.25-inch double shaft and #22 AWG length with a minimum length of 12 inches and 0.05 inches in diameter. To ensure stable mounting, it has four holes with diameters of 0.205 inches and four #4-40 ground screws.

T22NRHJ-LDN-NS-00 by Pacific Scientific is a Servomotor in the T Series. The T22NRHJ-LDN-NS-00 features a NEMA 23 (2.25 square) Motor Frame Size and a Mounting Configuration type of NEMA 23. This servomotor also has a Windings / Leads of 4 leads (Parallel connected) and J feedback. Additional specifications include a Rotor Stack Length of 2 and a Shaft Configuration/Modification of Rear shaft extension/Smooth.
