Structural Characteristics

1. Fully seamless mirror polished stainless steel body, sloped top surface to eliminate water pooling after washing
2. Integrated circular hygienic connector, no exposed terminal wiring susceptible to liquid ingress
3. Rear integrated holding brake module, compact coaxial layout without extra extension length
4. Smooth non-keyway output shaft eliminates food residue retention gaps at key grooves
5. Internal fully sealed stator assembly, secondary double-layer labyrinth waterproof structure

Working Principle

1. Three-phase sine wave alternating current input generates rotating magnetic field in stator winding
2. Permanent magnet rotor synchronously rotates with stator magnetic field to output precise mechanical torque and speed
3. Rear-end Hiperface DSL absolute encoder continuously collects real-time rotor absolute position data and transmits to AKD servo drive
4. Built-in PTC temperature sensor feeds winding thermal data to drive for overheat protection logic execution
5. 24V DC brake coil energization releases brake friction plate; power loss triggers spring mechanical locking of output shaft

Advantage Highlights

1. IP69K full washdown rating eliminates requirement for separate motor protective enclosures
2. AISI 316L stainless steel construction resists corrosion from sanitizing chemicals
3. Single-cable Hiperface DSL reduces on-site wiring material and installation labor cost
4. FDA food-safe materials allow direct contact with food production environments
5. Ultra-low torque ripple ensures smooth conveying, filling, cutting motion without product damage
6. Integrated holding brake eliminates separate external brake assembly for vertical axes

Applicable Industries

Installation Requirements

1. Flange front mounting only, stainless steel flange sealing surface must attach flat to machine mounting plate
2. Mounting surface surface roughness Ra ≤1.6μm to maintain IP69K sealing performance
3. M8 stainless steel flange bolts, tightening torque 12Nm evenly cross-tightening sequence
4. Cable connector oriented downward to prevent liquid accumulation inside connector housing
5. Maximum allowed shaft misalignment ≤0.02mm concentricity with driven load

Usage Precautions

1. All cleaning spray nozzles maintain ≥300mm distance from motor housing to avoid seal damage
2. Do not use abrasive metal brush for motor surface cleaning; only soft plastic brush and food-grade detergent
3. Brake coil power supply must maintain DC 24V ±5% voltage range to avoid incomplete brake release
4. Avoid long-term motor operation at continuous stall torque to prevent winding overheat
5. Conduct bearing grease replenishment maintenance every 8000 operating hours in high-wash environments
