103H5331-03CEE5 by Sanyo Denki

The 103H5331-03CEE5 stepping motor from Sanyo Denki is a high-performance actuator within the StepSyn Stepping Motors series, designed for demanding industrial automation tasks. This flange-mounted stepping motor offers a frame size of 103, matching standard 103 frame dimensions for streamlined integration. It delivers a precise step angle of 1.8° and a reliable holding torque of approximately 0.4 Nm under typical operating conditions. The motor operates on a rated voltage of approximately 5 V and draws a rated current of around 1.2 A, balancing power consumption with torque output. The robust 2-phase drive architecture ensures smooth motion and consistent performance across a wide range of speeds. With a lightweight construction of just 0.7 kg, it maintains high power-to-weight efficiency for compact machine designs.

Performance is optimized through compatibility with both full-step and micro-stepping control modes, enabling microstepping resolution for refined positioning and vibration reduction. A standard 5-wire connector configuration simplifies wiring and enhances electrical interfacing in complex control cabinets. The motor’s shaft diameter of approximately 5 mm supports precise coupling to gears, pulleys, or direct-drive shafts. Rated for operation in ambient temperatures from –20 °C to 60 °C, it maintains stable performance in varied environmental conditions. Its flange-mounted mounting style ensures rigid installation and minimal backlash during high-precision tasks. The inherent design of the stepping motor type delivers excellent torque retention at standstill, eliminating the need for brakes in most applications.

Built for long-term reliability, the 103H5331-03CEE5 features robust construction and tight manufacturing tolerances that minimize wear and extend service life. The broad operating temperature range and sealed windings guard against thermal degradation in harsh factory environments. Easy integration is supported through standardized mounting and electrical connections, reducing system assembly time. This module excels in industrial automation applications such as pick-and-place robots, CNC indexing tables, packaging machinery, and conveyor control systems. With its blend of precision, durability, and versatility, the 103H5331-03CEE5 stepping motor is an ideal choice for engineers seeking dependable motion control in demanding industrial settings.
