Product Description:

The 103G770-0121 stepping motor is a 2-phase synchronous motor engineered for precise and reliable operations especially through industrial automation; designed to operate directly on commercial AC power without needing a separate driving circuit, making it easy to integrate within diverse systems. This motor is notable for maintaining a constant rotation speed without slip over the load range to the motor torque, which is a crucial feature for any applications needing consistent performance that delivers high-performance output in dynamic environments. This model supports both 50 Hz and 60 Hz frequencies, offering flexibility for global use, and also demonstrates optimal ability enabling ultra-low speed rotation at exceedingly high torque. At a glance, its built-in specification features such as 2-Phase Synchronous Motor provides a straightforward integration with existing power grids and control infrastructures.

It is built particularly such that the operating voltage varies among models but they are rated roughly between 100–220 VAC, with common options available including 100 VAC, 120 VAC, and 220 VAC depending on regional infrastructure, further ensuring consistent operational capabilities through global variations. The current draw typically ranges from approximately 0.15 A up to 0.9 A, contingent upon the particular model selected, while the synchronous pull-out torque provides the muscle needed for a broad range of tasks, providing values from about 0.54 N·m to 5.5 N·m; it comes with the specifications for its capacitor, and some of its models will use values that could be around 3.75 µF at 60 Hz, along with the typical resistor values such as 180 Ω to 500 Ω, with examples citing 300 Ω. It's lead wire specifically is equipped with UL3266 AWG22 wiring.

Rated for operations inside of a broad spectrum, the ambient temperature conditions for best operation of this stepping motor extends from -10˚C to +50˚C, coupled with an ambient humidity scope stretching from 20% to 95% RH without condensation, providing reliable and consistent performance over time.
