Detailed content

Technical Specifications:

  • Motor Type: Brushless DC (BLDC), 3-phase
  • Rated Power: 170W continuous / 340W peak (30-second overload)
  • Rated Voltage: 24V DC (nominal) / 18–36V operating range
  • Rated Speed: 3000–8000 RPM (variable via PWM control)
  • Rated Torque: 0.54 Nm (continuous) / 0.85 Nm (peak)
  • Efficiency: ≥ 85% at rated operating point
  • Communication Interface: Hall sensor feedback (3-wire) + PWM speed input
  • Protection Rating: IP44 (motor housing) / IP20 (driver section)
  • Operating Temperature: -10°C to +60°C
  • Dimensions (Motor): Ø72mm × 120mm (approximate)
  • Weight: 1.8 kg

Material Composition:

  • Stator Laminations: Silicon steel, 0.35mm thickness, laser-cut
  • Rotor: NdFeB permanent magnets (N42SH grade), epoxy-encapsulated
  • Windings: Copper wire, Class F insulation (155°C rating)
  • Housing: Die-cast aluminum alloy (ADC12), powder-coated
  • Shaft: Stainless steel AISI 420, hardened to 55 HRC
  • Bearings: Sealed ball bearings (608ZZ), grease-lubricated lifetime

Structural Features:

  • Integrated driver PCB mounted on motor rear end
  • Hall sensor PCB with 120° spacing for commutation
  • PWM input connector (5V logic compatible)
  • Tachometer output (open-collector, 2 pulses/revolution)
  • Over-temperature protection: thermal switch embedded in stator winding
  • Over-current protection: electronic current limit at 8A

Working Principle: The integrated driver receives PWM speed command signal, reads Hall sensor positions to determine rotor angle, and sequentially energizes the three stator windings to produce rotating magnetic field. The permanent magnet rotor follows this field, producing continuous rotation. Speed is controlled by varying PWM duty cycle, which adjusts the average voltage applied to the windings.

Advantages:

  • Brushless design eliminates brush wear — lifetime exceeds 20,000 hours
  • Integrated driver reduces wiring complexity and installation time
  • High efficiency at partial loads — ideal for variable-speed applications
  • Compact form factor fits within confined appliance chassis spaces

Applicable Industries: AEG washing machines (drum drive), AEG dishwashers (circulation pump), AEG tumble dryers (drum motor), industrial automation

Installation Requirements:

  • Mount using provided 4-bolt flange pattern (M4 holes, 60mm spacing)
  • Connect PWM input to appliance main board (5V logic, 1kHz–20kHz frequency)
  • Ensure adequate airflow around motor housing for cooling
  • Ground connection mandatory — motor housing must be bonded to chassis

Usage Precautions:

  • Do not exceed 36V input voltage — risks driver IC damage
  • Do not block ventilation slots on motor housing
  • Verify Hall sensor wiring polarity before first power-on (reverse polarity destroys driver)
