Delta Electronics ECMA-E11315SS ASDA-A2 Series AC Servo Motor

Description

Precision motion control applications utilize the ECMA-E11315SS AC servo motor from Delta Electronics to deliver stable torque and precise speed regulation. Operating on a 220V supply, this 1.5 kW electrical commutation motor is engineered for high-performance automation tasks demanding rigorous closed-loop control. The unit belongs to the high-dynamic ASDA-A2 series, featuring a high-resolution 20-bit incremental encoder to ensure accurate position feedback to the drive controller.

Designed for industrial reliability, this model integrates a holding brake to maintain axis position during power loss or system disable states, alongside a durable oil seal to safeguard internal components against ingress from lubricants and coolants. Its physical configuration features a 130mm motor frame size and a standardized shaft with a keyway and screw hole for secure mechanical coupling.

Features

• 20-bit high-resolution incremental encoder for reliable positioning accuracy.
• Integrated electromagnetic holding brake for vertical axis safety and static positioning.
• Built-in heavy-duty oil seal protecting internal components from industrial fluid ingress.
• Standard 130mm frame size configuration enabling straightforward drop-in integration.
• Keyway with screw hole design ensuring secure shaft connection under dynamic loading.

Applications

• Multi-axis CNC milling, routing, and machining centers.
• Vertical axis actuators and z-axis lifters requiring safety holding brakes.
• Automated packaging machinery and high-speed sorting systems.
• Industrial robotics, gantry systems, and automated material handling equipment.

Installation Guidelines

• Flange Mounting: Ensure the 130mm mounting surface is flat and clean. Torque mounting bolts evenly to prevent stress concentration on the motor housing.
• Shaft Coupling: Use a flexible coupling designed for high-speed servo applications to accommodate minor radial or axial misalignments. Do not strike the shaft during installation as it may damage the internal encoder.
• Brake Control: Wire the integrated electromagnetic brake to a dedicated relay controlled by the servo drive. Do not use the holding brake for dynamic deceleration or stopping.
• Cabling: Route the power and encoder cables separately. Maintain minimum bending radiuses and ensure shield connections are grounded to minimize electromagnetic interference (EMI).
