Product Description:
The 103H7123-1745 StepSyn Stepping Motor which is part of the StepSyn Stepping Motors series is developed by Sanyo Denki.
Its features such as excellent speed and torque capabilities along with its effective communication and incremental encoder feedback makes it an optimal choice for industrial automation applications.
This 103H7123-1745 StepSyn stepping motor comes with a holding torque of 0.39 to 1.27 Nm which represents the torque the motor can maintain while at a standstill without losing position. It draws continuously maximum current of 40 amps without overheating which determines how much torque the motor can sustain over time. The maximum allowable current for short bursts is 73A which enables the motor to handle brief overloads or sudden acceleration without damage. It is designed to dissipate heat passively which means it does not have an integrated fan or liquid cooling. For extended operation at high loads proper ventilation and heat sinking may be required. The communication interface which is used to make connection with the computer or PLC which is a simple point-to-point communication protocol and RS485 that supports multiple devices on a single bus which allows for networked motion control applications. The electrical resistance is 0.51 Ω of each winding phase which affects efficiency, heating, and how much current the motor draws for a given voltage.
The 103H7123-1745 StepSyn stepping motor acquired a basic protection against solid objects larger than 12.5mm but no protection against water which means this model is suitable for clean, dry environments but not for dusty or wet conditions. It is recommended to place this module in an environment with humidity between 5% and 95% without condensation forming, which could cause corrosion or electrical failures.
Frequently Asked Questions about 103H7123-1745:
Q: How does the RS485 interface in the 103H7123-1745 StepSyn Stepping Motor improve motion control?
A: The RS485 interface allows multiple motors to be connected on a single communication bus. This enables synchronized and efficient networked motion control in industrial applications.
Q: Why is natural convection cooling used in the 103H7123-1745 StepSyn Stepping Motor instead of an integrated cooling system?
A: Natural convection eliminates the need for fans or liquid cooling, reducing mechanical complexity. Proper ventilation or heat sinking is recommended for prolonged high-load operation.
Q: How does the 0.51 Ω/phase winding resistance affect the performance of the 103H7123-1745 StepSyn Stepping Motor?
A: Lower winding resistance allows for higher current flow, improving torque generation. However, it also increases power dissipation, requiring effective thermal management for continuous operation.
Q: What benefits does the incremental encoder provide in the 103H7123-1745 StepSyn Stepping Motor?
A: The incremental encoder ensures real-time position feedback, enhancing precision in motion control. However, it does not retain position data after power loss, requiring homing on restart.
Q: How does the 7500 rpm max mechanical speed of the 103H7123-1745 StepSyn Stepping Motor impact applications?
A: The high-speed capability enables rapid positioning and fast cycle times. This makes it ideal for demanding automation processes requiring quick acceleration and deceleration.
