the rotor shall be rotated at low speed by the turning device and heated to more than 40°C for the rotor. (the rotor temperature is estimated by measuring thermal expansion of it.)
after the temperature of th rotor reaches to more than 40°C, the rotor speed can be increased.

用转子的温度来估计转子的热膨胀
after the temperature of th rotor reaches to more than 40°C, the rotor speed can be increased.
当转子的温度达到40℃以上时可以增速了
