About ECM-E3M-E21315SSE Delta Servo Motor + B 1500W M , Torque Nm - 7.16 , RPM - 2000
The ECM-E3M-E21315SSE is the 1500W (1.5kW) Medium Inertia version of the Delta E3 series, featuring a built-in electromagnetic holding brake ("S" suffix). It is designed for heavy-duty lifting and high-torque automation.
1. Physical Dimensions (Inches)
This motor uses the heavy-duty 130mm frame. The brake mechanism adds significant length compared to the standard model.

2. Weight
- Net Weight: Approximately 9.7 kg (21.38 lbs).
- Note: This is nearly 5 lbs heavier than the non-brake version due to the large heavy-duty brake assembly.
3. Key Functions
- Heavy Holding Power: The internal brake provides 12.0 N-m of holding torque. This is intentionally higher than the motors rated torque (7.16 N-m) to ensure a heavy vertical axis stays locked in place even during a complete power failure.
- High-Torque Performance: It delivers a constant 7.16 N-m of force, specifically optimized for a rated speed of 2000 RPM, making it a "muscle" motor for heavy machinery.
- Vibration Dampening: The medium-inertia rotor acts as a stabilizer, making it much easier to tune when the motor is moving heavy mechanical loads like large ball screws or industrial conveyors.
4. Technical Specifications
