Function & Performance Features

1. High torque density compact structure, small volume but stable output torque at low speed
2. Z37 multi-turn absolute encoder, no zero return required after power failure, save equipment reset time
3. Ultra-low torque ripple, suitable for high-precision constant speed conveying and positioning
4. Built-in temperature sensor, real-time overheat protection feedback to servo driver
5. Wide speed regulation range 0–3000 rpm, stable operation under micro-low speed working condition
6. Strong anti-vibration mechanical structure, adapt to high-frequency reciprocating motion equipment

Working Principle

1. Permanent magnet rotor generates fixed magnetic field inside motor stator
2. Servo driver outputs three-phase alternating current to stator winding to form rotating magnetic field
3. Rotor magnetic field interacts with stator rotating magnetic field to output precise torque and rotation speed
4. Z37 absolute encoder collects real-time rotor position data and feeds back to driver for closed-loop correction
5. Built-in thermal resistance monitors winding temperature, trigger driver overheat protection when temperature exceeds limit

Material Composition & Structural Characteristics

• Motor Housing: Die-cast aluminum alloy with black oxidation anti-corrosion coating
• Rotor: High-performance rare earth neodymium iron boron permanent magnet
• Stator Winding: High-temperature resistant enameled copper wire, Class 155 insulation
• Shaft: High-strength 45# steel quenched and tempered, wear-resistant surface treatment
• Encoder Shell: Sealed plastic dust-proof housing, waterproof silicone sealing ring

Installation Requirements

1. Standard flange surface mounting, use 4 M4 fixing bolts evenly tightened to avoid flange deformation
2. Flexible coupling must be installed between motor shaft and load shaft to avoid rigid connection radial force damage bearing
3. Cable wiring must reserve bending radius ≥10 times cable outer diameter, do not pull cable hard during installation
4. Install heat dissipation gap around motor housing, do not wrap motor with heat insulation materials

Application Scenarios

• PCB dispensing automatic equipment
• Small SMT chip mounter feeding axis
• Precision packaging labeling machine positioning axis
• Mini CNC engraving machine feed drive
• Electronic product testing equipment motion platform

Usage Precautions

1. Do not overload peak torque for more than 3 seconds continuously, permanent magnet may demagnetize
2. Avoid water splashing on shaft output end; install waterproof protective cover in humid workshop
3. Regularly check coupling fastening state every 3 months to prevent loose positioning deviation
4. Do not disassemble encoder rear cover without professional tools, will lose absolute zero position data
