Brake Stopping Energy Screen

WHAT THIS SCREEN ANSWERS

Stopping a moving system is an energy problem before it is a brake part-number problem. Rotating inertia stores kinetic energy, and a raised load can add potential energy that must be controlled. Stopping time then changes the average power that a brake, motor, resistor, or other mechanism must absorb. This screen exposes those terms in one preliminary view.

Enter reflected rotational inertia, speed, any relevant raised mass and vertical stop distance, plus the target stopping time. MechPlane calculates rotational kinetic energy, potential energy, their sum, and average braking power. The model intentionally separates energy from torque and deceleration profile because a brake can be constrained by heat even when a torque number appears adequate.

Real stopping events are rarely uniform. Deceleration shape, friction, gravity direction, compliance, gearbox efficiency, motor regeneration, repeated cycles, ambient temperature, brake adjustment, wear, and actuation delay can materially change outcomes. A vertical application also requires a separate load-holding and fail-safe review. No generic energy result can establish a safety function.

Use this output to identify the energy path and start a supplier conversation. Confirm brake torque, thermal capacity, duty, fade, emergency-stop behavior, control sequence, redundancy, holding needs, and applicable guarding or safety requirements. Treat any personnel-exposure, lifting, or emergency-stop application as a qualified review problem, not a calculator result.
