Also, the load would have to be adjusted accordingly to not exceed the motor nameplate current rating. The frequency of the source and the number of the motor poles sets the basic speed of the induction motor so motors can operate at 50 or 60 Hz line frequencies but obviously the speed will change and the voltage needs to be provided accordingly to keep the Volts/Hz ratio constant, when not using a VFD. You can check the condition of the motor by performing a megger, Hipot, and surge comparison test to determine if it has been damaged. Phase Converter, Single Phase to 3 Phase Converter, MY-PS-20-F Model, Suitable for Forklift Charger, more than 2.0 tons 200-240V, Input/Output 200V-240V. Also, the motor should be protected with a thermal overload device, not just an upstream circuit breaker. If you ran a 480V / 60 Hz motor at 380V / 50 Hz the volts/hertz ratio would be maintained but with it being 380V / 60 Hz you have not maintained the volts/hertz ratio. Discover VEVOR Variable Frequency Drive, AC 220V Input 4KW Variable Frequency CNC Drive Inverter Converter, VFD 5.5HP 1 or 3 Phase Input, 3 Phase Output, CNC Motor Inverter Converter for Motor Speed Control, Unique Control Method and High-Quality Material at lowest price, 2days delivery, 30days returns. Tips: If I run a 3-phase motor rated 460V 60Hz on a 380V 60Hz power supply what will happen?įor motors not driven by a variable frequency source the volts/hertz ratio should stay constant to keep the magnetic fields compliant with the motor design. In this video I show my setup that I use to take 220VAC single phase household power and create both 230VAC 3 phase and 460VAC 3 phase power using a rotary phase converter and a 3. Instantaneous power failure protection and alarm device

With overload, short circuit, over temperature You can just adjust converter output frequency in the range (40-400Hz) for 400Hz option.Ĥ digit, digital frequency meter, resolution 0.1Hz/StepĤ digit, digital voltage meter, resolution 0.1VĤ digit, digital ammeter, resolution 0.1AĤ digit, digital Watt meter, resolution 0.1W When the output is ≤120Hz, the load capacity can reach 100% of the rated value. When the output is 400Hz, the load capacity can only reach 50% of the rated capacity.
