About ECM-E3M-E21310RSE Delta Servo Motor 1000W M , Torque Nm - 4.77 , RPM - 2000
The Delta ECM-E3M-E21310RSE is a high-torque 1kW (1000W) Medium Inertia servo motor. It belongs to the E3 series, but unlike the previous models you asked about, this "E" class motor is optimized for higher torque at a lower rated speed.
1. Performance Specifications
- Rated Power: 1000 W (1.0 kW)
- Rated Torque: 4.77 N-m (42.22 lb-in)
- Max (Peak) Torque: 14.31 N-m (126.65 lb-in)
- Rated Speed: 2000 RPM
- Maximum Speed: 3000 RPM
- Inertia Type: Medium Inertia (8.58 10 kgm)
2. Physical Dimensions (Inches)
This motor uses a much larger 130mm frame, making it significantly bulkier than the 750W (80mm) model.

3. Key Functions
- Heavy-Duty Torque: With nearly 4.8 N-m of continuous torque, this motor is designed for heavy industrial machinery, such as large CNC axes, heavy-duty belt conveyors, and industrial mixers.
- Stability at Low Speed: Because its rated speed is 2000 RPM (instead of the usual 3000), it provides more stable torque delivery at lower speeds without needing high gear reductions.
- High Resolution: It maintains the 24-bit encoder (16.7 million pulses/rev), ensuring that even with its high power, its positioning is accurate to the micron.
4. Weight & Protection
- Net Weight: Approximately 5.3 kg (11.68 lbs).
- Protection Rating: IP67 (dust-tight and water-resistant).
Compatibility
This motor must be paired with the ASD-E3-1021-L/M/E (1kW) servo drive.
The Delta ECM-E3M-E21310RSE functions as a high-torque, industrial-grade actuator designed for heavy mechanical loads. Because it is a 1000W (1kW) Medium Inertia motor, it serves a specific role in large-scale automation.
Core Functions
- High-Force Delivery: Its primary function is providing 4.77 N-m of continuous torque. It is built to move heavy componentslike large milling heads, heavy-duty conveyor belts, or massive lead screwsthat smaller 400W or 750W motors cannot handle.
- Low-Speed Stability: Unlike your previous 3000 RPM motors, this model is rated at 2000 RPM. This makes it more functional for tasks requiring "muscle" at lower speeds, reducing the need for complex gearboxes.
- Load Smoothing (Medium Inertia): The heavier internal rotor acts as a stabilizer. Its function is to prevent vibrations and "jitter" when the motor is attached to a large, heavy mechanical system (high load-to-motor inertia ratio).
- Ultra-Precise Positioning: Even though it is powerful, it uses a 24-bit encoder (16.7 million pulses/rev). This allows it to function with sub-micron accuracy, ensuring that a 50kg load stops exactly where commanded.
Common Industrial Applications
- Heavy CNC Machining: Driving the X, Y, or Z axes on large-format milling or cutting machines.
- Material Handling: Operating high-capacity lifts or heavy-duty indexing tables.
- Industrial Packaging: Controlling the main drive of large palletizing robots or wrapping machines.
- Textile & Paper Mills: Managing tension in heavy winding and unwinding rolls.
