Based on operation parameters of a three phase induction motor at dutytype S1, this paper deduces the thermal state of this motor with constant output at dutytype S7.
This paper introduces dutytype S4 of motor for crane and metallurgical applications and the test method to determine outputs of the motor at varied cyclic duration factor and starting times.
