Full-load torque is 49.39 N·m.

  • At 7.5 kW and 1450 RPM, the shaft delivers 49.39 N·m of turning force.
  • This torque level suits general-purpose industrial drives, compressors and machine tools.

Next stepDivide torque by the arm length to find the equivalent linear force, or multiply by the gear ratio for a gearbox output.
