Say Goodbye to Overheating and Stuttering — Coolmay SD Series EtherCAT Low‑Voltage Servos

Coolmay launches the SD series high-performance bus-type low-voltage servos to address common pain points in long-running servo applications—overheating, stuttering, complex tuning, and overload damage—providing stable, efficient drive solutions for a wide range of automation equipment.

• Wide DC input: Supports DC 24–60 V, compatible with most low-voltage systems without extra transformers, simplifying integration and lowering wiring and procurement costs.
• Bus models: SD-115-EA and SD-130-EA with EtherCAT for high-speed real-time communication, fast multi-axis data exchange, and low multi-axis synchronization error.

1. Automatic parameter identification: Driver auto-detects motor parameters (torque, encoder, pole pairs, etc.) after wiring, reducing commissioning time and avoiding manual errors.
2. Intelligent anti-stall algorithm: Real-time load and current monitoring limits output torque on jamming or stall events, preventing sustained overload, overheating, and coil damage.
3. High-precision control: Optimized position and speed dual-loop algorithms provide smooth low-speed motion, accurate high-speed start/stop, and stable repeatability for assembly, dispensing, engraving, and precision sorting.

4. Multiple operating modes: Built-in position, velocity, and torque modes let a single servo meet conveying, gripping, indexing, and light stamping needs, reducing drive variants and spare-part inventory.

   Optimized thermal design: Improved power-component layout, enhanced cooling structure, and intelligent temperature control enable 24/7 continuous operation with controlled temperature rise and no performance stutters.

   Applications SD series servos balance performance and cost for small- and mid-size automation: AGVs, small lithium-battery machining, desktop robots, compact sorting lines, and portable automation devices—streamlining development and delivering reliable motion control.
