The importance of the Speed-Torque Gradient in DC Motor Sizing

Often overlooked when sizing DC motors is the Speed-Torque Gradient. The Speed-Torque Gradeint is defined as  Δn / ΔM  [rpm/mNm] . The speed / torque gradient is an indicator of a motor's performance.  The smaller the value, the more powerful the motor and consequently the less motor speed varies with load variations.  It is based on the … Continue reading The importance of the Speed-Torque Gradient in DC Motor Sizing
