DC Motor Speed & RPM Calculator

Calculate RPM, angular velocity (rad/s), linear velocity, gear ratio reductions, and motor voltage relationships.

DC Motor Speed & Angular Velocity Calculator
Formulas & Physics

Output RPM: Nout = N / G
Angular Velocity: ω = (2π · Nout) / 60 rad/s
Linear Velocity: v = ω · r m/s

Example: 6000 RPM with 30:1 gearbox gives 200 RPM (20.94 rad/s).
