Product Description:
The Sanyo Denki engineered the component number 103H7121-0411 and is incorporated in the StepSyn Stepping Motor product line. It has almost 0.45 N·m holding torque at the rated current guarantees exact load retention. Its phase resistance of around 3.6Ω per phase controls current flow rather well. The product’s phase inductance of 3.8 mH per phase encourages fast magnetic field response. These key specifications provide consistent performance in controlled motion uses.
Standard connection compatibility for the motor has a shaft diameter of around 6mm, which enables perfect integration with current mechanical systems. The module roughly -20C to +50C working temperature range assures thermal stability and consistent performance in a range of environments. It is categorized as a Stepping Motor to assist in precise incremental motions, therefore improving delicate positioning jobs. It gives great resolution in motion control with a step angle of around 1.8 every full step. With the rated voltage of around 4.1 V, low-power DC operation is effectively supported. Its rated current of around 1.1 A per phase guarantees strong performance of electrical driving.
The motor's 200 steps per revolution help to provide consistent and smooth spinning. Further, it runs with a bipolar drive that increases control accuracy and torque production. Its DC voltage type also makes the design of the power supply easier. With around 0.00002 kg·m² specification of rotor inertia, the mechanical load during acceleration is minimized. The benefits for noise-sensitive installations come from another independent statistic showing the noise level at around 45 dB at rated speed. The 103H7121-0411 further combines these thorough technical standards to provide consistent and precise stepping action.
