Technical details and manufacturing context for Vibration Motor/Exciter

Definition
In a Product Screening System, the vibration motor/exciter is the core component that produces oscillatory motion to vibrate screening surfaces, enabling efficient separation, sorting, and classification of materials based on size, shape, or other physical properties.
Working Principle
Converts electrical energy into mechanical vibration through an unbalanced rotating mass (eccentric weight) or electromagnetic force, creating centrifugal force that induces controlled oscillations in the screening equipment.
Common Materials
Electrical steel, Copper windings, High-strength alloy steel
Technical Parameters
  • Eccentric weight diameter and offset distance determining vibration amplitude (mm) Standard Spec
Components / BOM
  • Eccentric Weight
    Creates unbalanced rotational force to generate vibration
    Material: High-density steel alloy
  • Stator Windings
    Converts electrical energy to magnetic field for motor operation
    Material: Copper with insulation
  • Rotor Assembly
    Rotating component that drives the eccentric weight
    Material: Electrical steel laminations
  • Bearing Housing
    Supports rotating shaft and withstands vibration loads
    Material: Cast iron or steel
Engineering Reasoning
0.5-5.0 mm amplitude at 50-3000 Hz frequency, 0.1-15.0 kN force output
Coil insulation breakdown at 180°C, bearing seizure at 0.02 mm radial play, shaft fracture at 450 MPa stress
Design Rationale: Electromagnetic hysteresis heating exceeding Class H insulation limits, fatigue crack propagation from alternating torsional loads exceeding 10^7 cycles at 300 MPa stress amplitude
Risk Mitigation (FMEA)
Trigger Unbalanced mass eccentricity exceeding 0.5 mm from geometric center
Mode: Resonant vibration amplification at 1.5x natural frequency causing structural fatigue
Strategy: Dynamic balancing to ISO 1940 G6.3 standard with 0.1 g·mm/kg residual unbalance
Trigger Permanent magnet demagnetization at 150°C Curie temperature threshold
Mode: 40% torque reduction and phase current increase to 125% rated value
Strategy: Samarium-cobalt magnets with 750°C Curie point and active cooling maintaining 80°C maximum
