Term Explanation
M
0
Static torque Thermal limit torque of motor when stationary. This torque can be provided by the motor for
any length of time.
I
0
Static current Effective value of motor winding current which is required to generate the rated torque.

Limit curve Motors can only be loaded with 5 times the rated current
Field weakening area The maximum peak torque output in the field weakening area depends on the voltage reserve.
Typical torque characteristics are proportional to the function 1/f or 1/n.
