Technical Features | Precision Control Meets High Efficiency

1. Core Performance Parameters

Power & Torque:

• SB145/30/08/05/24/S/3B/64/EAKN Rated power: Estimated 1.5kW–2.2kW (refer to selection manual).
• Rated torque: 2.7 Nm (example; actual value based on code “270”).
• Peak torque: Exceeds 3× rated torque for short-term overload demands.

Speed Range:

• Rated speed: 3000 rpm (supports high-speed light-load or low-speed heavy-load modes).
• Speed ratio: 1:5000 (stepless regulation for multi-condition switching).

Encoder Resolution:

• Standard configuration: 20-bit absolute encoder (1,048,576 pulses/rev) for micrometer-level accuracy.

2. Electrical & Mechanical Design

Voltage Compatibility:

• Three-phase AC 200V/400V (global industrial grid compatibility).

Protection Rating:

• IP65 (dustproof and waterproof, ideal for humid/dusty environments).

Structural Optimization:

• Low-inertia design: Reduces acceleration time for packaging machinery, robot joints.
• High-inertia design: Enhances low-speed stability for CNC feed axes.

3. Communication & Extension Functions

Bus Protocols:

• Supports EtherCAT, CANopen, Modbus TCP for seamless PLC/HMI integration.

Additional Options:

• Brake: Built-in or external module for vertical-axis anti-fall.
• Oil seal: Special design to prevent lubricant leakage in food processing equipment.
