What is angular acceleration?

Angular acceleration (α) is the rate of change of angular velocity. SI unit is rad/s². It is related to torque by Newton's second law for rotation: τ = I × α.

How do I convert RPM/s to rad/s²?

Multiply RPM/s by 2π/60 ≈ 0.10472. For example, 100 RPM/s = 10.472 rad/s².

What are typical angular accelerations for motors?

Stepper motors: 10–100 rad/s². Servo motors: 100–10 000 rad/s². Large industrial motors have lower values limited by torque and inertia.

Convert between all common angular acceleration units in three groups: Radians (rad/s², mrad/s², rad/min·s, rad/min²), Degrees (°/s², °/min·s, °/min²), and Revolutions (rev/s², RPM/s, RPM/min). Includes rotational dynamics reference values for electric motors, servo motors, CNC spindles, and Newton's second law for rotation (τ = I × α). Adjustable precision, scientific notation, swap units, copy any row.
