Term Explanation
M
0
Standstill torque Thermal limit torque of the motor at standstill. The motor can
deliver this torque for an unlimited length of time.
I
0
Standstill current Effective value of the motor phase current required to generate
the standstill torque.
M
N
Nominal torque Thermal limit torque of the motor at nominal speed n
