About ECM-E3M-C20602RSE Delta Servo Motor 200W M , Torque Nm - 0.64 , RPM - 3000
The Delta ECM-E3M-C20602RSE is a high-performance
200W brushless AC servo motor from the
ASDA-E3 series. This specific "M" model indicates it has
medium inertia, which provides more stable control for applications with varying loads compared to low-inertia models. [

Physical Dimensions (Inches)
The 200W motor uses a larger
60mm frame than the 100W model you were looking at previously. [

Core Specifications
- Rated Power Output: 200W
- Rated Torque: 0.64 N-m (Peak torque up to 1.92 N-m)
- Rated Speed: 3000 RPM (Max speed 6000 RPM)
- Inertia Type: Medium Inertia (better for belt-driven or high-load-ratio systems)
- Encoder: 24-bit high-resolution optical encoder
- Weight: Approximately 1.1 kg (2.43 lbs) [1, 2, 3, 4, 5]
Key Functions
- Stability: The medium inertia design helps prevent "hunting" or vibration when moving mechanical loads that are significantly heavier than the motor itself.
- Precision: Like other E3 motors, it offers ultra-fine positioning accuracy thanks to the 16.7 million pulses per revolution encoder.
- Environmental Protection: Rated IP67, meaning it is fully protected against dust and can withstand temporary immersion in water.
The primary function of the ECM-E3M-C20602RSE is to provide stable, high-torque rotary motion for industrial automation. While similar to the 100W models you asked about, this 200W Medium Inertia motor serves a specific role in larger mechanical systems.
Core Functions
- High-Torque Performance: It delivers a constant 0.64 N-m of torque, which is double the power of the 100W model. This allows it to push heavier mechanical loads or overcome higher friction.
- Medium Inertia Stability: The "M" in the model name means it has a heavier internal rotor. This functions as a "mechanical buffer," making it much easier to control when attached to heavy pulleys, long lead screws, or belt-driven slides. It prevents the "jitter" or vibration often seen in low-inertia motors.
- Closed-Loop Precision: Using its 24-bit encoder, the motor functions with the driver to ensure the shaft reaches its exact commanded position (down to 0.00002 degrees) and stays there, even under load.
- Dynamic Speed Control: It maintains consistent performance from a slow crawl up to 3000 RPM (and can burst up to 6000 RPM), allowing for fast cycle times in production lines.
Where it is typically used
Because of the increased torque and stability, this motor is the "workhorse" for:
- Small CNC Milling/Lathes: Driving the X and Y axes where tool pressure is present.
- Conveyor Systems: Handling consistent movement of goods where weight varies.
- Material Feeding: Precision unwinding or feeding of paper, plastic, or metal coils.
- Automated Gates/Valves: Where high starting torque is needed to move a static load.
Key Technical Advantage
The main functional advantage of this specific model is its Torque-to-Inertia Ratio. It can handle a load inertia up to 10-15 times its own, whereas lower inertia motors usually struggle beyond a 5:1 ratio.
The ECM-E3M-C20602RSE is a 200W medium inertia motor. Because it is part of the larger 60mm frame series, its dimensions and weight are notably higher than the 100W models.

Key Comparison: 100W vs. 200W
Unlike the 100W motor which uses a 40mm (1.57") frame, this 200W motor steps up to a 60mm (2.36") frame. This larger size allows it to provide double the torque (0.64 N-m) and handle more demanding mechanical loads without losing precision.
Pro Tip: If you ever switch to the brake version of this 200W motor (SSE model), the length will increase to 5.45 inches (138.5 mm) and the weight will go up to 1.6 kg (3.53 lbs).
