RATTMMOTOR YPMC-750W 110V Servo Motor Kit
The 750W 110V servo motor kit from RATTMMOTOR integrates a high-torque A2M110-80SV02430 motor with a compact driver (S2SVD15-110). It delivers up to 2.4 N.m rated torque and up to 7.2 N.m peak torque, with a rated speed of 2500 r/min and peak speed of 3000 r/min. The motor employs a 17-bit encoder and IP65 protection, supporting robust operation in demanding environments. A built-in disturbance torque observer helps resist external disturbances, ensuring stable motion. The kit is suitable for CNC engravers, milling machines, and robotics projects that require precise, reliable servo control. Note that CN-port based controllers may require separate customization for PC/PLC connections.
RATTMMOTOR YPMC-750W 220V Servo Motor Kit
This variant switches to 220V operation, providing similar torque characteristics with a higher potential performance envelope. The A2M80SV02430 motor maintains 2.4 N.m rated torque and 7.2 N.m peak torque, with a top speed around 3,000 r/min. The driver (S2SVD15) supports 220V input and up to 15A, enabling stable control under heavier loads. The kit shares IP65 protection and 17-bit encoding for precise positioning. It suits CNC routers, engraving machines, and automation projects that require reliable high-torque servo performance at 220V mains.

Rated at 220V with a 17-bit encoder, the M864S driver supports SVPWM control and broad input/output flexibility. The IP65 protection rating and substantial current range (up to 16.5A) make it a robust option for CNC arcs, milling heads, and robotic actuators in tougher environments. It combines high power with a flexible control interface, suitable for larger hobbyist or light industrial setups
Buying Guide: How To Choose The Right Servo Motor And Driver
- Voltage compatibility: Match motor voltage with your power supply (110V vs 220V) and verify driver ratings to prevent overheating and ensure clean commutation.
- Torque and speed needs: Identify required rated torque and peak torque for your load, plus the desired operating speed. Higher torque helps with heavier tools, while speed matters for rapid cycles.
- Encoder resolution: Higher encoder bit depth (e.g., 17-bit) improves positioning accuracy and repeatability, especially in CNC milling and precise robotics.
- Protection and durability: IP ratings (IP65 vs IP54) indicate resistance to dust and water exposure. Consider environmental conditions in your workshop.
- Control interface: Controllers with CN ports, RS-232/RS-485, or Modbus enable PC or PLC integration. Ensure compatibility with your host system.
- Noise, heat, and efficiency: Look for low-noise operation and efficient cooling (air cooling is common). This affects comfort and long-term reliability in busy workshops.
- System integration: For multi-axis setups, plan connectors, cabling, and mounting hardware. Some kits include everything you need, while others require sourcing components separately.
- Budget and scalability: Higher-power kits offer more headroom for future upgrades, but ensure the chosen components fit your current project scope.
