Electric Motor Torque Table: Torque (Nm) by kW and Speed

Published: 10.10.2026 Updated: 22.10.2026 492 views

The torque values below are the catalogue values of HEM Motor’s own three-phase motors. Alongside the rated torque, we also give the starting and breakdown torque in Nm, calculated from the catalogue ratios, so you can compare them directly with what your machine needs.

Same power, different speed: how does torque change?

At constant power, torque rises as speed falls. For the 7.5 kW motors in our catalogue, rated torque at 3000 rpm is 24.4 Nm, at 1500 rpm 49.1 Nm, at 1000 rpm 73.8 Nm. This is why 1500 or 1000 rpm motors are usually preferred for machines with a high starting load, such as conveyors, mixers and crushers.

Electric motor torque – speed chart: torque of 4, 7.5, 11 and 22 kW motors — At the same power, a 1000 rpm motor has about three times the torque of a 3000 rpm motor.

What do the columns mean?

Rated torque (Mn): The torque the motor delivers continuously at full load.
Starting torque: The torque the motor can deliver when starting from standstill (Mn × Ts/Tn).
Breakdown torque: The highest short-term torque the motor can carry without stalling (Mn × Tmax/Tn).

Choosing the right motor for your machine

If the torque (Nm) and speed your machine needs are known, choose a motor whose rated torque is above that value and whose starting torque covers the machine’s break-away load. For applications with a gearbox, the gear ratio must also be taken into account. If you are not sure, call us on +90 532 345 49 86.
