The maximum of instaneeous torque line: the motor starting the maximum torque of motor , instantaneous impact load; beyond the torque value, over-current protection will lead to stop.
Short-term running area: when the motor at different speed, it can operate in a short time during this torque range. but after a long time it can cause heating of the motor, resulting motor break or drive overheat protection start, cause stopping working.
Rated torque Rated torque of the motor line: at different speeds, the motor can run for a long time in this moment.
In Continuous operation area: at different speed, the motor can operate continuous.
