Product Description:
The 103H89223-0941 is a stepping motor produced by Sanyo Denki for the StepSyn Stepping Motors series. It is intended for indexers and positioning axes where open-loop motion is adequate, translating pulse trains into incremental rotation without external feedback. By combining a hybrid rotor with a two-phase stator, the motor provides high holding torque for mid-frame automation equipment while maintaining simple wiring for distributed drive panels.
The motor can sustain a holding torque of 15.5 N·m, allowing fixtures to remain fixed against process forces when pulses stop. Each control pulse advances the shaft by 1.8°, providing 200 discrete steps per revolution for repeatable angular placement. The phase windings draw 4 A per phase, so the selected drive must supply this current in unipolar mode. Electrical response is influenced by a winding inductance of 9.7 mH per phase and a resistance of 1.4 Ω per phase. A lead-wire harness provides access to the two-phase coil set and supports the motor’s unipolar connection. The rotor inertia is 22 × 10⁻⁴ kg·m², balancing acceleration capability against overshoot during rapid start-stop operation. Mechanical attachment uses a flange with a diameter of 106 mm. The single output shaft includes a key so couplings or pulleys can transmit torque without slipping.
For radial loading, the bearings tolerate up to 340 N, while axial thrust along the shaft is limited to 100 N. These load limits should be considered when setting belt tension or installing the motor in a vertical orientation. The body has an overall length of 221.3 mm, which must be accommodated by the mounting plate and surrounding equipment. Its mass of 10.5 kg should also be considered when the motor is installed on a moving gantry. A single-shaft layout leaves the rear of the housing unobstructed, and unipolar wiring supports motion controllers that use phase-common drive circuits.
