Product Description:
The P2HNRXB-LDN-M1-00 is a two-phase hybrid stepper motor manufactured by Pacific Scientific for the POWERMAX II P Motors series. Intended for positioning and incremental feed duties in machine tools, pick-and-place heads, and small conveyors, the unit converts digital pulse trains from a drive into precise angular movement. Its compact form allows it to serve as a motion element inside automated assemblies. The motor can support applications that use encoders, gears, or lead screws to control mechanical movement.
In parallel wiring, the motor draws 2.6 A per phase from the drive, and each phase presents 0.76 Ω of DC resistance and 1.9 mH of inductance. These electrical values affect current rise time and available torque across the operating speed range. With a half-stack magnetic assembly, the motor delivers 59 oz-in of static holding torque, while its detent torque is limited to 2.5 oz-in to help keep mid-band resonance low. The 1.812-inch encoder bolt circle and rear 0.75-inch extension accommodate feedback devices when an application requires tighter accuracy than the stated ±1.5% step error. Each commanded step advances the rotor by 1.8 degrees through the B-type winding and standard rotor tooth geometry.
The motor completes a full revolution in 200 discrete steps, and it is compatible with microstepping drives that can produce smoother motion. Its frame follows the NEMA 23 standard and has a 2.625-inch mounting bolt circle with 0.200-inch holes for installation on common brackets. The double smooth shaft measures 0.250 inch in diameter and provides connection points at both ends of the motor. The windings are protected by a Class B, 130 °C insulation system rated for 340 VDC and an insulation resistance of 100 MΩ. Standard lead wires exit through a mating receptacle for straightforward cable routing. The motor supports operation at ambient temperatures from -20 °C to +40 °C without derating.
