Maximum shaft speed is 3000 RPM under no-load conditions. The motor weighs approximately 4.2 pounds.

‌Functional Features‌
The double-ended shaft allows mounting of loads on both sides of the motor for bidirectional drive configurations. The motor provides smooth low-speed operation with minimal resonance when paired with a compatible microstepping drive. It offers high torque-to-inertia ratio for rapid acceleration and deceleration. The motor includes 8 lead wires for series, parallel or unipolar wiring configurations. The precision-ground shaft ensures minimal runout for coupling alignment.

‌Application Scenarios‌
This motor is used in CNC milling and routing machines, laser cutting and engraving equipment, automated packaging and labeling systems, semiconductor wafer handling platforms, medical imaging device positioning stages, textile machinery and 3D printing gantry systems where repeatable accuracy is essential.

‌Performance Parameters‌
The motor maintains positional accuracy within 0.05 degrees per full step under rated load. Detent torque is 450 ounce-inches. The thermal time constant is 35 minutes from cold to rated temperature. The motor is rated for continuous operation at rated current with adequate heatsinking. Ambient operating temperature range is -20 degrees Celsius to +50 degrees Celsius. The unit meets NEMA 23 dimensional standards with a 2.3 inch square mounting flange.

‌Material Composition‌
The stator is constructed from stacked high-silicon electrical steel laminations to minimize eddy current losses. The rotor uses rare earth neodymium permanent magnets bonded to a laminated steel core. The shaft is hardened stainless steel with precision ground surfaces. The housing is die-cast aluminum alloy with a clear anodized finish. Bearings are sealed precision ABEC 5 ball bearings pre-lubricated with high-temperature grease.

‌Structural Features‌
The motor features a NEMA 23 square flange with four mounting holes on a 1.378 inch bolt circle. The double shaft extends through both front and rear endshields with flat machined surfaces for coupling attachment. Terminal connections are via a 6-inch flying lead cable with color-coded wires. The housing includes mounting holes for face or bracket installation. The design provides IP50 protection against dust ingress.

‌Working Principle‌
The stator contains two windings displaced by 90 electrical degrees. When pulsed current is applied sequentially to each phase by the drive, the rotor magnetically locks to the energized stator poles and advances by one step angle per pulse. Microstepping drives subdivide each full step into finer increments by proportioning current between phases, achieving smooth motion and sub-micron positioning resolution.

‌Installation Requirements‌
Mount the motor on a rigid machined surface using the four mounting holes with specified torque. Align the motor shaft precisely with the driven load using a flexible coupling to compensate for minor misalignment. Do not apply axial or radial thrust loads exceeding 5 pounds on the shaft. Ensure the drive provides adequate current limiting and cooling. Route motor cables away from high-voltage conductors and use shielded cable if running longer than 6 feet.

‌Usage Precautions‌
Never exceed the rated current of 6 amperes per phase as this will cause overheating and demagnetization of the rotor. Avoid operating the motor at its natural resonant frequency range of 150 to 250 Hz without microstepping to prevent excessive vibration. Do not drop or impact the motor as the permanent magnets are brittle. Do not disassemble the motor as it is not user-serviceable. Store in a dry environment to prevent corrosion of the shaft and bearings.
