Can I run 460VAC 60hz60Hz 3 phase rated motors on 380V 50hz50Hz mains?

I have an upcoming project that is going to China which will be using 380Volt 50hz380Vl volt 50Hz. My question is willWill motors that I've used before which are rated for 460V 60hz60Hz, be able to operate @ 380Volt 50hzat 380V 50Hz?

I've read online that as long as the Voltagevoltage to Frequencyfrequency ratio is the same ( closeclose to the same  ) that the motors should be able to operate but just at a slower rate (20% less speed.) Is this claim true?

If so, should I spec my 460V 60Hz motors to be 20% larger than what I normally use in order to account for this 20% drop in speed?
