• Frame Size: 90L
• Mounting: B3 (foot-mounted with flange)
• Ambient Temperature: -15°C to +40°C
• Weight: Approximately 11.5 kg

Material Composition:

• Frame: Aluminum alloy die-cast (ADC12)
• Stator Core: Silicon steel laminations (M400-50A grade, 0.5 mm thickness)
• Rotor: Aluminum die-cast squirrel cage
• Shaft: Carbon steel C45, keyed
• Bearings: Deep groove ball bearing (6205-2RS, sealed)
• Terminal Box: Glass-fiber reinforced polyester (GRP), IP55

Structural Features:

• Foot-mounted with flange (B3 configuration) — allows direct coupling to driven equipment
• Terminal box rotatable in 4×90° positions for flexible cable entry
• Lifting eye bolt on top frame for safe handling
• External fan cover for forced air cooling (IC411 cooling method)

Working Principle:
Three-phase AC current applied to stator windings creates a rotating magnetic field at synchronous speed (1500 RPM for 4-pole, 50 Hz). The rotating field induces current in the aluminum rotor cage, producing torque. The rotor speed (1390 RPM) is approximately 7.3% below synchronous speed — this slip is necessary for torque production. The external fan mounted on the shaft forces air over the frame ribs for cooling.

Key Advantages:

• IE2 efficiency reduces energy consumption by up to 15% versus IE1 motors
• IP55 protection allows use in dusty and wet industrial environments
• B3 mounting enables direct mechanical coupling without additional brackets
• Aluminum frame provides excellent heat dissipation and corrosion resistance
• Low-noise operation at 68 dB(A) at rated load

Applicable Industries:

• Conveyor belt drives
• Centrifugal fans and blowers
• Small pump systems
• Packaging machinery
• HVAC auxiliary equipment

Installation Requirements:

• Mount on a rigid, level base using M10 anchor bolts
• Align motor shaft with driven equipment shaft within 0.05 mm TIR
• Connect power cables to terminal box — L1/L2/L3 and PE
• Verify rotation direction before connecting load

Usage Precautions:

• Do not operate above rated voltage — insulation stress will accelerate aging
• Ensure adequate ventilation clearance: minimum 300 mm on all sides
• Check bearing temperature regularly — should not exceed 90°C
• Lubrication-free sealed bearings — do not attempt to re-grease
• Perform insulation resistance test (≥100 MΩ at 500V DC) quarterly
