My dept has acquired a Vac pump/blower unit, both of which are driven by European standard motors(380-415V, 50Hz, 3kW and 7.5 kW,2880 rpm and 1440 rpm). I have not been able to find a vendor for a suitable 10 hp ,460V, 1800 rpm replacement motor with D flange mounting.
Other than the 20% speed increase and 20% torque decrease, what effects can I expect if I run the 50Hz motors on our 480V service?
