About ECMA-C20401RS Delta Servo Motor 100W L , Torque Nm - 0.32 , RPM - 3000

The ECMA-C20401RS is a 100W low-inertia AC servo motor from the Delta Electronics ASDA-B2 Series. It is designed for high-speed, high-precision applications like electronics assembly and packaging. [1, 2, 3, 4]

Key Specifications

Rated Power Output: 100W (0.1 kW).
Rated Torque: 0.32 N-m, with a peak torque of approximately 0.96 N-m.
Rated Speed: 3000 RPM, with a maximum speed capable of reaching 5000 RPM.
Encoder: 17-bit incremental rotary optical encoder (160,000 ppr).
Frame Size: Compact 40mm x 40mm square flange.
Shaft Details: 8mm diameter shaft with a keyway and oil seal, but no internal brake (indicated by the "R" in the suffix). [1, 2, 3, 4, 5, 6, 7, 9]

Compatibility and Use

Servo Drive: Specifically designed to pair with the ASD-B2-0121-B drive for standard industrial applications.
Environment: Rated IP65 (excluding the connector), making it resistant to dust and water splashes.
Control Modes: Supports position, speed, and torque control via the compatible drive. [, 2, 3, 4, 5]

The primary function of the ECMA-C20401RS servo motor is to provide precise, high-speed mechanical motion within a closed-loop control system. It converts electrical energy from a servo drive into exact rotational displacement, speed, or torque. [1, 2, 3]

Operational Roles

Precision Positioning: Using its built-in 17-bit incremental encoder, the motor tracks its exact position (160,000 pulses per revolution) to ensure it reaches a specific target angle set by a controller like a PLC.
Closed-Loop Feedback: The motor constantly sends "eye" data (position and speed) back to the drive. This allow the system to make instant micro-corrections, preventing errors that occur in standard motors.
High Dynamics: As a low-inertia motor, its main function is to handle rapid start-and-stop cycles. It can accelerate from -3000 RPM to 3000 RPM in as little as 10ms without a load. [1, 2, 3, 4]

Key Control Modes

When paired with an ASDA-B2 drive, the motor functions in three primary modes: [1, 2]

Position Mode: Moves to a specific coordinate (e.g., for CNC or indexing).
Speed Mode: Maintains a constant rotational velocity (e.g., for conveyors).
Torque Mode: Applies a constant force (e.g., for tension control in winding or capping).

Application Examples

Electronics Assembly: High-speed pick-and-place movements.
Packaging Machinery: Precise bottle-capping or labeling where torque and position must be exact.
Textile Machines: Maintaining constant tension on threads. [1, 2, 3]

The ECMA-C20401RS is a compact motor. Below are the physical specifications converted into inches and pounds: [1]

Physical Dimensions

Frame Size (Width x Height): 1.575" x 1.575" (40 mm x 40 mm).
Total Length: Approximately 3.97" to 5.38" (101 mm to 136.8 mm), depending on whether you measure the motor body alone or include the shaft extension.
Shaft Length: 0.984" (25 mm).
Shaft Diameter: 0.315" (8 mm). [1, 2, 3, 5]
