CALCULATORS / ELECTROMECHANICAL

Motors and actuators

Motor and load parameters with explicit operating limits.

two of torque, power and speed, efficiency → remaining quantity, input power

voltage, resistance, torque constant, load → speed, current, mechanical power

load torque-speed envelope, duty, bus voltage → current demand, power, candidate motor constraints

load, inertia, acceleration, torque-speed data → required torque, increment, speed limits

load motion, inertia, gearing, duty → peak and RMS torque, speed demand

load inertia, ratio, motor inertia → reflected inertia, ratio tradeoff

motor envelope, desired output torque and speed, efficiency → feasible reduction ratios

winding resistance, bus voltage, driver limit → unlimited stall estimate, limited startup current

wire dimensions, length, temperature, current → resistance, copper loss

speed, flux or voltage constant, resistance, current → back EMF, bus-voltage requirement

loss profile, thermal resistance/capacitance, ambient → temperature estimate, transient response

turns, current, gap, pole area, magnetic assumptions → idealized force, saturation and leakage caveats

load, stroke, speed, duty, efficiency → force, power, screw or cylinder requirements

free stroke, blocked force, load stiffness → loaded stroke, force, stiffness tradeoff

force constant, current, resistance, motion → force, heat, acceleration demand
