Product Description:
The 103H6704-0440 stepping motor is produced by Sanyo Denki within the StepSyn Stepping Motors series. It uses a 50 mm square flange to fit compact indexers and positioning stages, while a single round output shaft transmits torque directly to couplings or pulleys. The motor is supplied with lead wires, and its unipolar wiring is routed through AWG22 conductors for direct connection to a suitable driver. In automated machinery, the device converts command pulses into repeatable angular increments, allowing precise feed control without requiring a feedback sensor. This operating method is suitable for indexing tables, compact conveyors, and positioning mechanisms that move through predetermined distances.
Each revolution is divided according to the motor’s 1.8° basic step angle, allowing a controller to command 200 discrete positions per turn without microstepping. When energized at standstill, the rotor provides 0.52 N·m of holding torque for light-load clamping and start-stop operation. The windings draw 2 A per phase and have a resistance of 1.7 Ω per phase, producing manageable resistive losses for a motor of this size. An inductance of 3.8 mH per phase influences how quickly winding current rises during acceleration and helps limit high-frequency current ripple. The rotor inertia is 0.14 × 10⁻⁴ kg·m², supporting rapid indexing when the connected load is matched appropriately. An external driver should regulate phase current according to the winding requirements to prevent excessive heat during repeated motion cycles.
The shaft end supports a radial force of up to 74 N and a thrust force of up to 15 N within the motor’s bearing load limits. The assembly weighs 0.55 kg, which helps reduce the moving mass of linear stages and other mobile mechanisms. Its body depth is 55.8 mm, allowing installation in compact multi-axis layouts where space behind the mounting plate is limited. The aluminum housing transfers heat away from the windings during operation, although adequate clearance should be maintained around the motor for heat dissipation. A properly matched coupling also helps prevent excessive shaft loading and reduces vibration during repeated acceleration and deceleration cycles.
