SP2566-5200

SP2566-5200 is a Sanyo Denki motor in the F SANMOTION Stepping Motors series. Its basic step angle is 1.8°, which determines the angular movement produced by each full step, while its static angle error is ±0.054° for positioning accuracy. The motor produces 1.7 N·m of holding torque to maintain shaft position when energized. Its rated current is 3 A per phase, and the rotor inertia is 0.36 × 10⁻⁴ kg·m², indicating the rotor’s resistance to changes in rotational speed.

The winding resistance is 1 Ω per phase, which affects current flow and heat generation, while the winding inductance is 4.4 mH per phase and influences current response during stepping. The insulation withstands 1500 VAC, and the Class F thermal rating permits operation of the insulation system up to +155ºC. An IP65 protection grade provides enclosure protection against dust and water jets.

The shaft has a diameter of 6.35 mm and supports an allowable radial load of 23 N and an allowable thrust load of 15 N. These ratings indicate the permitted forces perpendicular and parallel to the shaft, respectively. The mounting pilot has a diameter of 38.1 ±0.025 mm for alignment during installation. The motor is 102 mm long and has a mass of 1.2 kg.
