motor regulation factor

The motor regulation factor, measured by R/k2 where R is the coil resistance and k is the torque constant, is a critical measure of motor’s power density over its performance lifetime. The lower the motor regulation factor the lower will be the heat loss at higher loads, thus enabling the motor to retain high power density with sustained endurance.

Rはコイル抵抗、kはトルク定数。k2はk2。motor regulation factorが小さいほど、高負荷時の熱損失が少なく、そのぶん長い時間にわたってモーターは高い出力密度が保てる。
