Calculadora de Torque de Motor Gratis
Calcula el torque de un motor eléctrico a partir de potencia y velocidad. Resultado en N·m o lb·ft.
Full-Load Torque
98.45 N-m
Full-Load Torque vs Motor Rated Power
Fórmula
## Motor Full-Load Torque Torque is calculated from the motor nameplate power and rated speed. ### Formula **T = P x 60 / (2 pi N) = 9549 P / N** where P is power in watts, N is speed in RPM, and T is torque in N-m. The constant 9549 comes from 60/(2 pi) x 1000 for kW input.
Ejemplo Resuelto
A 15 kW motor running at 1455 RPM.
- 01T = 15,000 x 60 / (2 x pi x 1455)
- 02T = 900,000 / 9,142 = 98.44 N-m
- 03T = 98.44 x 0.7376 = 72.61 lb-ft
Preguntas Frecuentes
What is the difference between full-load and starting torque?
Full-load torque is the continuous rated torque. Starting (locked rotor) torque is the torque at zero speed during startup, typically 150-300% of full-load torque for standard induction motors.
Does motor efficiency affect torque?
The nameplate kW is the mechanical output power. Electrical input power is higher (input = output / efficiency). The torque formula using output kW gives the shaft torque directly.
How do I select a motor for a given torque requirement?
Determine the required torque at operating speed, add a service factor (typically 1.15-1.25), then select a motor whose full-load torque exceeds this. Also check starting torque, breakdown torque, and duty cycle.
