Function & Feature Highlights

1. Medium inertia rotor balances rapid acceleration and stable low-speed operation, effectively suppresses mechanical oscillation of ball screw and belt transmission structures
2. 23-bit multi-turn absolute encoder eliminates homing operation after equipment power restart, saves production preparation time and avoids positioning safety risks
3. Integrated 24V power-off holding brake locks output shaft tightly when power is cut, prevents workpiece displacement on vertical axis equipment
4. Class F high-temperature winding insulation allows long-time continuous heavy-load operation without winding thermal degradation
5. Low cogging torque design (<1% rated torque) realizes ultra-smooth rotation at ultra-low speed, no jitter for precision cutting and printing equipment
6. Magnetic encoder design avoids glass code disc breakage risk under strong vibration, higher mechanical reliability than optical encoders
7. IP65 front housing resists coolant splash, cutting oil mist and dust in machining workshop environments
8. Wide voltage brake coil supports industrial standard 24VDC control power supply, compatible with all mainstream PLC relay output modules

Material & Structural Characteristics

• Motor Housing: Die-cast aluminum alloy with black oxidation anti-corrosion coating, internal cooling fin structure for passive heat dissipation
• Stator Winding: High-purity copper enameled wire with Class F high-temperature insulation coating, vacuum impregnated epoxy resin to eliminate winding vibration noise
• Rotor Core: Laminated silicon steel sheet embedded with high-performance neodymium iron boron permanent magnet, high magnetic energy density for large torque output
• Output Shaft: Medium carbon alloy steel, quenched and tempered heat treatment, anti-wear and anti-deformation under frequent impact load
• Encoder Housing: Reinforced plastic sealed shell with rubber waterproof gasket, isolated from motor winding heat source to protect encoder chip
• Brake Assembly: Spring pressure friction disc brake structure, copper coil winding with high temperature resistance insulation
• Connectors: Metal threaded locking aviation plugs, integrated rubber sealing rings to prevent liquid and dust ingress

Working Principle

1. Servo drive outputs three-phase variable frequency alternating current to motor stator winding, generating rotating magnetic field
2. Permanent magnet rotor interacts with stator rotating magnetic field to produce continuous electromagnetic torque, driving output shaft to rotate
3. Built-in 23-bit absolute magnetic encoder real-time captures rotor angle, rotation speed and multi-turn position data, transmits digital feedback signal back to servo drive
4. Drive internal DSP compares command position and encoder feedback position to execute closed-loop position/speed/torque control
5. When equipment power is cut off, electromagnetic brake coil loses excitation; internal spring pushes friction disc to lock motor shaft, maintaining mechanical position
6. Stator winding temperature resistance wire feeds temperature alarm signal to drive; drive automatically reduces output torque when winding overheating occurs to avoid burnout

Installation Requirements

1. Horizontal or vertical mounting both supported; vertical upward shaft installation requires additional dust baffle to prevent coolant accumulation on shaft seal
2. Mounting flange contact surface must be flat and clean without metal debris; evenly tighten four flange mounting bolts with torque 2.0–2.5 N·m
3. Power cable and encoder cable must use original factory shielded cables; separate routing from high-current welding cables with minimum 20cm spacing
4. 24VDC brake power supply must be independent power loop; do not share power with sensor signal circuits to avoid brake release delay
5. Install flexible coupling between motor shaft and mechanical load; rigid direct connection transmits vibration and damages encoder internal components
6. Maintain unobstructed natural convection space around motor housing; multiple motors installed densely need auxiliary cabinet exhaust fans

Application Scenarios

• Vertical injection molding machine clamping and ejection servo axes
• Precision CNC engraving, milling machine feed drive motors
• Automated vertical lifting warehouse material handling axes
• Textile high-speed winding, warping machine tension control
• Electronic assembly equipment vertical Z-axis pick-and-place positioning
• Metal cutting machine tool feeding spindle auxiliary drive

Operation & Maintenance Notes

1. Do not frequently switch brake power on and off in short cycles; repeated friction disc wear reduces brake holding torque service life
2. Encoder aviation plug must be fully threaded and locked; loose connector causes position loss and sudden equipment collision
3. Wipe motor housing cooling fins with dry compressed air every 4 months in machining workshops to remove cutting dust accumulation
4. Avoid motor continuous operation at 0 RPM stall state for more than 1 minute; static winding current generates excessive heat and damages insulation
5. Absolute encoder battery-free design does not require regular battery replacement, but avoid disassembling rear encoder housing randomly
6. If shaft oil seal leaks cutting fluid, replace oil seal immediately; liquid penetration will corrode internal bearing and encoder assembly
