Description

The ECM-B3M-E21315SS1 is a high-precision AC Servo Motor from the Delta ECM-B3 series, engineered for high-performance motion control. This motor is classified as a medium inertia unit, making it ideal for applications that require a balance between responsiveness and load stability. It features a rated power output of 1.5 kW and operates at a rated speed of 2000 rpm on a 220V supply.

A standout feature of this model is its 24-bit incremental optical encoder, which provides exceptional resolution for ultra-precise positioning and smooth motion control at low speeds. The physical design includes a 130mm frame size, a keyed shaft with an integrated oil seal, and an electromagnetic brake, ensuring safety and position holding when the motor is de-energized.

Installation Guidelines

• Mounting: Use high-strength bolts to secure the 130mm frame to the machine structure. Ensure the surface is flat to avoid mechanical stress on the motor housing.
• Brake Connection: Ensure the brake power supply (typically 24V DC) is correctly wired and sequenced with the servo drive to prevent premature wear of the brake pads.
• Shaft Alignment: Use flexible couplings when connecting to the load to prevent radial forces that could compromise the oil seal or bearing life.
• Thermal Management: While the motor is rated for industrial duty, ensure adequate airflow to prevent overheating, especially during high-cycle-rate applications.
