Locked rotor time tE for increased safety motor
Locked rotor time tE for increased safety motor
(OP)
For the increased safety motor (type "EExe"), the temperaturse rise of both the stator and the rotor shall be measured during a locked rotor test. Shall I consider the temperatures reached when the power is shut down (after tE seconds) or shall I take into consideration the termal inertia and wait for the temperatures to reach their maximum values, several seconds after the end of the test?
