SANMOTION New stepper drivers have advantages of low temperature rise

A Stepper Driver Solution for Extended Life and Quieter Operations

As an equipment manufacturer, you understand the challenges—balancing optimal performance, reliability, and cost-effectiveness. This article unveils a pivotal solution to enhance your machinery’s lifespan, mitigate maintenance costs, and elevate user satisfaction. Dive into the additional benefits of our new stepper drivers, specifically engineered for extended equipment life, reduced downtime, and a quieter, more efficient workplace.

We conducted tests comparing the temperature rise and sound levels of two of our prominent stepper driver models—BS1D and the latest F2BFD. The results are not just numbers; they represent a leap forward in performance, ensuring a superior experience for equipment makers and end-users alike.

Temperature Rise Comparison:

Our temperature rise comparison between the previous model, BS1D, and the new model, F2BFD, reveals a striking difference. The F2BFD showcases exceptional thermal performance, maintaining a steady 30°C during operation. In contrast, the BS1D exhibits a temperature rise nearing 44°C. That is 47% lower in comparison. This data underscores the superior temperature performance of the F2BFD, translating to enhanced reliability and prolonged equipment life. Next, I will explain each benefit more closely.

1. Extended Equipment Life and Reliability:

  • Prolonged Operation: The low temperature rise in our stepper driver ensures that electronic components operate within a safe range, promoting an extended lifespan for your equipment.
  • Enhanced Reliability: Lower operating temperatures minimize stress and wear, reducing the risk of overheating-related failures and enhancing the overall reliability of your machinery.

2. Cost-Efficiency and Productivity:

  • Reduced Maintenance Costs: Stepper drivers with lower temperature rise require less maintenance, resulting in substantial cost savings throughout the lifespan of your equipment.
  • Minimized Downtime: Equip your machinery with low temperature rise stepper drivers to experience fewer unexpected failures, reducing downtime and contributing to increased productivity.

3. Optimal Performance and Energy Efficiency:

  • Consistent Performance: Stepper drivers operating at lower temperatures provide a stable and consistent performance, ensuring optimal functionality in precision-demanding applications.
  • Energy Efficiency: Lower temperature rise correlates with better energy efficiency, reducing the energy needed for cooling systems and contributing to overall energy savings.

The Sound Level Comparison:

Beyond temperature, we delved into sound level performance, a crucial factor in noise-sensitive environments. The F2BFD demonstrated a smooth and steady sound level curve, devoid of spikes, even at higher speeds. The previous model, BS1D, exhibited a spike around 80 RPM, while the F2BFD showed a mild increase until around 270 RPM, it then started to decrease. This nuanced comparison highlights the F2BFD’s ability to provide a quieter and more consistent user experience, especially in applications where noise levels matter.

4. Silent Operation for Enhanced User Experience:

  • Enhanced Workplace Comfort: Our stepper drivers boast low noise levels, creating a quieter working environment.
  • Adaptability to Noise-Sensitive Environments: In applications like medical equipment or office automation, low noise levels ensure a seamless and unintrusive user experience.


In precision-driven industries, our F2BFD stepper driver extends equipment life and enhances workplace comfort with its low-temperature rise and noise levels. Offering a practical and effective solution, it ensures cost-effective operation, marked by reduced maintenance, minimized downtime, and improved energy efficiency—an advancement in motion control technology.
