Product Description:
The 103H5505-70EG2 is a Stepper Motor that is part of the StepSyn Stepping Motors series. The motor is a product of the Sanyo Denki company. The module is best used for industrial automation practices.
The 103H5505-70EG2 Stepping Motor rotor inertia is 0.03 × 10⁻⁴ kg·m² which means it can accelerate and decelerate quickly and is suitable for applications that need rapid and precise movements. The width of the motor face is 42 mm which places it in the NEMA 17 category. The electric current drawn by each phase of the module is 0.75 A/phase which suggests that it can provide at least 0.75 A per phase to operate the motor correctly. It comes in a weight of 0.23 kg which is important when calculating load for robotics arms, drones or moving platforms. It comes with a single shaft with a round type of flat edge which allows for a set screw to grip it securely (commonly seen in pulleys, gears or couplings) to prevent slippage. It is made to hold maximum torque of 0.127 N·m when powered but not rotating. The module body length is approximately 50 to 60 mm which implies high torque capacity.
The 103H5505-70EG2 stepping motor shaft rotates 0.036° with each step due to which it has extremely high resolution which makes it ideal for precision positioning. It is a standardized motor size with a 42 mm x 42 mm faceplate and standard mounting holes which ensures compatibility with mounts, brackets and mechanical designs that follow the NEMA spec. It is capable of providing maximum torque of 0.33 × 10⁻⁴ kg·m² while still maintaining step accuracy under acceleration. The recommended supply voltage of the motor is 24 volts DC which generally allows for faster response times and better performance.
Frequently Asked Questions about 103H5505-70EG2:
Q: How does the 0.036° step angle of the 103H5505-70EG2 motor benefit precision applications?
A: The 0.036° step angle enables extremely fine movements, ensuring highly accurate positioning. This makes the 103H5505-70EG2 ideal for applications requiring micrometer-level adjustments.
