Simulation conditions

  • The simulation conditions are examples. We perform individual simulations based on the customer's specifications.
    • Continuous rated torque is expressed (duty100%).
    • Heat radiation condition: Natural heat radiation
    • Environmental temperature: 40°C
    • Winding maximum temperature: Up to 85°C
  • Rotation detector is not considered.

Formula for calculating torque

√3/2 × torque constant between terminals Kt (N·m/A) × motor current lm [A]

  • Motor constant and torque constant on this brochure mean constants between terminals.
