ELAU SM070-60-010-P0-45-S1-B0
Technical Specifications Brand: ELAU Model: SM070-60-010-P0-45-S1-B0 Motor Type: Permanent magnet synchronous AC servo motor Frame Size: 70 mm Rated Speed: 6000 rpm Rated Torque: 1.0 Nm Shaft Type: Smooth shaft, 45-degree mechanical feature specification Encoder Type: Built-in high resolution absolute encoder Winding: Standard P0 winding variant Brake: S1 holding brake equipped Protection Grade: IP64 for motor body Operating Temperature: -20°C to +40°C
Functional Features High torque density compact rotor structure reduces installation space occupation. Integrated absolute encoder provides rotor position information immediately upon power-up without homing operation. Built-in electromagnetic holding brake locks the motor shaft when power cuts off to prevent load drifting. Low cogging torque ensures ultra-smooth rotation at low speed. High dynamic response supports rapid acceleration and deceleration for high-speed automation cycles. Robust sealed motor housing protects internal windings and encoder from dust and liquid splashes.
Application Scenarios Packaging machine multi-axis synchronized motion, food processing automation, pharmaceutical packaging lines, printing machinery, automated material handling systems.
Performance Parameters Low cogging torque minimizes speed fluctuation during low-speed operation. High acceleration capability for fast cyclic motion tasks. Absolute encoder retains position data after power loss. Holding brake provides reliable shaft locking under static load conditions. Consistent torque output across the full operating speed range.
Material Composition Motor Housing: Aluminum alloy die casting. Rotor: Silicon steel lamination stack with rare-earth permanent magnets. Stator: Copper magnet wire wound inside silicon steel stator core. Shaft: High-strength alloy steel. Encoder Housing: Reinforced plastic with sealing gasket. Brake Assembly: Electromagnetic coil, friction disc and pressure spring components. Seals: Nitrile rubber sealing rings.
Structural Features Cylindrical compact motor body with 70mm square flange mounting structure. Front output shaft fitted with shaft sealing ring. Rear housing integrates absolute encoder and holding brake assembly. Two separate cable connectors for motor power cable and encoder feedback cable. Flange mounting holes for direct attachment to machine mechanical frame.
Working Principle The servo drive supplies three-phase alternating current to the motor stator windings. The generated rotating magnetic field interacts with permanent magnets mounted on the rotor to produce electromagnetic torque and drive shaft rotation. The built-in absolute encoder continuously measures rotor angle and rotational speed and sends feedback signals back to servo drive. When power supply is disconnected, the electromagnetic holding brake engages via spring force to clamp the motor shaft and fix load position.
Installation Requirements Mount the motor flange firmly to machine frame with specified torque for flange bolts. Align motor shaft and mechanical load coupling carefully to avoid excessive radial and axial load. Use dedicated shielded ELAU power cable and encoder cable. Install cable strain relief to prevent pulling force on motor connectors. Reserve air circulation space around motor housing for heat dissipation. Perform encoder direction and phase sequence verification after wiring completion.
Usage Notes Do not apply radial or axial load exceeding motor bearing rating. Keep motor connector area clean from dust, oil and liquid contamination. Release holding brake before manually rotating motor shaft. Check motor operating temperature under continuous operation. Avoid mechanical impact on motor shaft and encoder rear housing during installation.
