ELAU SR-05860005P021S1B0T
Technical Specifications Brand: ELAU Model: SR-05860005P021S1B0T Motor Type: Permanent magnet synchronous AC servo motor Frame Size: 58 mm Encoder Type: Built-in absolute position encoder Brake Configuration: Integrated spring-actuated holding brake Protection Class: IP64 Operating Temperature Range: -20°C to +40°C Shaft Specification: Standard smooth output shaft Winding Variant: P021 winding option
Functional Features High torque density compact rotor structure reduces overall machine footprint. Absolute encoder retains rotor position data upon power loss, eliminating mandatory homing operation after power restart. Built-in holding brake locks motor shaft when power supply cuts off and prevents load displacement during power interruption. Low cogging torque ensures smooth rotation at ultra-low operating speed. High acceleration capability supports fast cyclic motion sequences in continuous automation production. Sealed motor housing blocks dust and splash contamination to protect internal windings and encoder assembly. Optimized winding design matches ELAU PacDrive drive control algorithm.
Application Scenarios High-speed packaging machinery, food and beverage automated production lines, pharmaceutical blister packaging equipment, printing converting machines, multi-axis pick and place automation systems.
Performance Parameters Consistent torque output across full rated speed range. Minimal torque ripple during low speed operation. Fast dynamic response for rapid acceleration and deceleration cycles. Holding brake provides full static load locking capacity. Stable encoder signal transmission under continuous mechanical vibration.
Material Composition Motor Housing: Die-cast aluminum alloy. Rotor: Laminated silicon steel stack embedded with rare-earth permanent magnets. Stator: Copper magnet wire wound on silicon steel stator core. Output Shaft: High-strength hardened alloy steel. Encoder Housing: Reinforced engineering plastic fitted with nitrile rubber sealing gasket. Brake Assembly: Electromagnetic coil, friction disc and pressure spring components. Shaft Seals: Nitrile rubber sealing rings.
Structural Features Compact cylindrical body with 58mm square flange mounting interface. Front output shaft equipped with rotary shaft seal. Rear housing encapsulates absolute encoder and holding brake unit. Two separate electrical connectors dedicated for motor power cable and encoder feedback cable. Flange mounting holes for direct attachment to machine mechanical frame. Internal physical isolation between power winding chamber and encoder compartment.
Working Principle The paired ELAU servo drive supplies three-phase variable frequency alternating current to stator windings. The generated rotating magnetic field interacts with permanent magnets mounted on rotor and creates electromagnetic torque to rotate motor shaft. The integrated absolute encoder continuously measures rotor angular position and rotational speed, sending real-time feedback signals back to servo drive. When system power supply disconnects, spring force engages holding brake friction disc to clamp motor shaft and fix mechanical load position.
Installation Requirements Secure motor flange firmly to machine frame with bolts tightened to specified torque value. Align motor shaft and mechanical coupling accurately to avoid excessive radial and axial bearing load. Use ELAU dedicated shielded power cable and shielded encoder feedback cable. Install cable strain relief fixtures to prevent tensile force acting directly on motor connectors. Reserve air circulation clearance around motor housing for heat dissipation. Complete wiring connection then verify encoder phase definition and motor rotation direction before formal commissioning.
Usage Notes Do not apply radial or axial load exceeding motor bearing rated capacity. Maintain motor connector region free of oil, dust and liquid contamination. Release holding brake before manually rotating motor shaft. Monitor motor housing temperature during continuous cyclic operation. Avoid mechanical impact to output shaft and rear encoder housing during installation and maintenance.
