DC Motor Torque–SpeedLive

where torque meets power

Stall torque (N·m)

No-load speed (rpm)

Load torque (N·m)

A DC motor trades torque for speed along a straight line: maximum torque at stall, maximum speed at no load. Mechanical power (torque × speed) peaks right in the middle, at half the no-load speed. Educational tool.

Operating speed300 rpm

Output power25.1 W

Peak power26.2 W @ 250 rpm

Governing equation

τ = 2 (1 - \frac{ω}{500}), ω_{o p} = 300 rpm

Reading this result: Light load: the motor spins up past half-speed toward no-load, trading available torque away for RPM.
