R88M-K3K020F-S2 Omron G5 Series High Power AC Servo Motor

Product Overview

The Omron R88M-K3K020F-S2 is a robust, high-performance AC servo motor belonging to the renowned G5 Series (OMNUC G5). Designed for demanding industrial automation, this 3 kW motor delivers a perfect balance of high torque, precision control, and durability. With a rated speed of 2000 rpm and a maximum torque of 14.3 Nm, it is engineered to drive heavy loads with exceptional accuracy.

Featuring an IP67 protection rating (with a 20-bit serial encoder), this motor is built to withstand harsh environments, including dust, water jets, and oil. The "K3K020F" model indicates a 3 kW power rating, 2000 rpm speed, and a keyed shaft configuration, while the "S2" suffix denotes a standard specification set suitable for general-purpose high-inertia applications. It is the ideal choice for applications requiring rigid positioning and smooth motion profiles.

Key Features & Benefits

• High Torque Density: Delivers a maximum torque of 14.3 Nm in a compact, lightweight frame (approx. 10.9 kg), allowing for high dynamic response and rapid acceleration/deceleration.
• Superior Environmental Resistance: Achieves IP67 protection (IEC standard) for the motor body and encoder, making it suitable for use in washing machines, food processing lines, and outdoor machinery without additional enclosures.
• High-Precision Feedback: Equipped with a standard 20-bit incremental encoder (1,048,576 pulses/rev), providing ultra-fine resolution for precise positioning and smooth low-speed operation (minimized torque ripple).
• Standardized Connectivity: Features a connector-type terminal box (Connector) for easy wiring and maintenance, compatible with the R88D-KT series G5 drives.
• Keyed Shaft (Model "K"): Comes with a standard keyway on the shaft for secure coupling transmission, ideal for high-load inertia applications.
• Global Compliance: Certified with CE, UL, CSA, and TUV marks, ensuring safe operation and easy integration into global machinery exports.

Technical Specifications

System Integration

The R88M-K3K020F-S2 is designed to be paired with the R88D-KT series servo drives. This combination forms a complete servo system supporting advanced control modes such as Position Control, Speed Control, and Torque Control. It is also compatible with Omron’s 1S servo configuration software for easy auto-tuning and parameter setup.

• Recommended Drive: R88D-KT08H / KT15H / KT30H (depending on control mode and power supply requirements).
• Cable Requirements: Requires specialized servo motor power cables (e.g., R88A-CA1A series) and encoder cables.

Typical Applications

• Heavy-Duty Packaging: Form-fill-seal machines, case packers, and palletizers requiring high torque at start-up.
• Machine Tools: CNC spindle drives (via belt/gear) or axis feed drives for milling and grinding machines.
• Material Handling: Conveyor systems, automated guided vehicles (AGVs), and hoisting mechanisms.
• Plastic & Rubber: Injection molding machines and extruders requiring precise pressure and speed control.
• General Machinery: Industrial robots (4-6 axis), printing presses, and textile machinery.
