    Tips: Can a motor with frequency of 60 Hz be connected to a 50 Hz power supply?

    When the power supply voltage is constant, the power supply frequency is low, which is unfavorable for the operation of the motor. First, the increase in the magnetic flux density of the motor causes the core flux to saturate. At this time, the excitation current of the magnetic flux increases, so the increase of the total current of the stator of the motor increases, and the iron loss of the motor increases. The motor efficiency is reduced, the heat generation is increased, and the temperature rise is increased. According to the formula of the rotation speed n1=60f/p, n1 decreases, and the rotor rotation speed also decreases, so that the air volume is reduced, the heat dissipation is poor, and the motor temperature rises.

    In order to use a 60 Hz motor for a 50 Hz power supply and not to generate heat, a method of lowering the power supply voltage can be used. Take a 380 volt motor as an example. In order to make the motor not overcurrent, it is necessary to maintain the magnetic flux density unchanged. Under the 50 Hertz power supply, the voltage at which the magnetic flux density is constant is (50/60) X380 = 317 volts. That is to say, as long as the power supply voltage drops to 317 volts, 60 Hz, the 380v motor will not generate heat on the 50Hz, 380v power supply. But pay attention to the following two issues. First, the motor speed will be reduced by about 17%. Second, since the voltage is 83% of the rated voltage, the power used after the step-down is only 83% of the original motor power.

    In this case, ATO recommends using frequency converter as a standard power supply. AC power supply can step-up & step-down frequency and voltage, output pure sine wave, convert fixed frequency to the required frequency and voltage.

    3-Phase Frequency Converter
    We will be moving in a few weeks and want to make sure our current units will work in the new place. Our new building will have 240V 3-phase power. If the 3-phase frequency converter cannot run directly on 240V, what are some solutions we can explore?
    From: Gloria | Date: 07/05/2024
    Was this review helpful? Yes No (0/0)
    ATO Responded
    The normal input voltage range of our converter is 208VAC ±10%. If the voltage exceeds 240V, it falls outside the unit's voltage range, and we do not recommend using 240V directly. We suggest adding an autotransformer of the same capacity at the front end of the converter. Then, reduce the voltage from 240V to 208V through the autotransformer, which is a better solution.
    If you agree to add an autotransformer solution, you can tell us your available single-phase voltage and three-phase voltage respectively.
    A calibration procedure for frequency converter
    Would you be able to provide us with a calibration procedure for this product?
    The time has come for calibration and our end-user wants to ensure the unit is calibrated before using it for qualification tests.
    Thanks.

    If the actual output voltage of the converter is the same as the voltage displayed on the LCD panel without error, you do not need to calibrate the converter.
    I have some more questions about the converter
    I have some more questions about the converter.
    On page 12 there is a note stating that the input/output cable diameter should be doubled if over 20 meters. What is the reasoning behind this?
    Is it for voltage drop? Is that the total length from the source panel?
    Or does that get “reset” if there was a disconnect before the converter?
    Also, are there any torque specifications on the input/output terminals?
    From: kamran | Date: 15/06/2023
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. Yes, there is indeed a voltage drop over a distance of 20 meters, but the voltage drop is relatively small, about 0.3V. If you do not have high requirements on the accuracy of the output voltage, you do not need to amplify the cable specifications. Or you can make the actual output voltage of the converter 1-2V higher than the set voltage, which is also available.
    2. If the input power line is disconnected or there is a phase loss, the converter will be powered off for protection.
    Input/Output
    Hello
    we are manufacturing a machine compatible with European voltages (230/400VAC 50Hz).
    This machine must also be able to be powered from an airport (115/200VAC 400Hz) as well as with USA voltage (120/210VAC 60Hz).
    Can you confirm that it is possible to have 115/200VAC 400Hz three phase input and 230/400VAC 50Hz output?
    Is the input voltage/frequency adjustable to 120/210VAC 60Hz or do I need to order another one with these specifications?

    Thank you in advance for your reply.

    We can provide single-phase frequency converter with 115V 400Hz input and 120/240V 60Hz split-phase voltage output (L1, L2, N), with a capacity of about 10kVA. The three-phase input 400Hz version is not yet available. For more information, please contact our sales email sales@ato.com or technical team email support@ato.com.
    Frequency converter damaged in first try out
    I purchased a 10 kVA 3-phase 480V 60Hz / 380V 50 Hz frequency converter. Sadly in our first try-out it got damaged. Initial supply with 400V 50 Hz output was working, but the Infy BEG1K0110 requires some internal charging when changing the state from HALT to ON which seems to trip the current limit of the frequency converter as it always turned off with an error. In our second attempt we made use of another "start-mode" of Infy BEG1K0110, where the internal circuit get's charged via it's DC output. This way we were able to turn on, and apply a load of about 5 kW but soon tripped our laboratories 16A AC circuit breaker (supply for frequency converter).

    The current suggestion is that regarding the tripping of the 16A AC circuit breaker (powering the drive), is this circuit breaker used with leakage protection? If yes, please replace the circuit breaker with a type without leakage protection, and test again. Check if the circuit breaker still trips.
    If the problem persists, pls open converter side covers, and power on the converter, then take a video showing us the internal main circuit boards, especially the ones with red led indicators and beeping sound, and show us the converter display as well while the converter is running. Also, send us the nameplate of the converter for confirmation so we can proceed to the next step.

    Complicated programming is not required! As you said, it's just to adjust the converter outputs for required frequency and voltage, no more.
    According to my requirements, which frequency converter do you recommend to me?
    We need to test a unit that powers on at 115V ±5% at 400 Hz. We are supposed to verify that its output voltage and it has an output current of 1A. We are looking to connect the frequency converter to a standard 120 v at 50Hz outlet. What do you recommend?

    I need a product that can convert voltage
    Hi, is there something that can change a European machine that runs on 230 V 50/60 hz 700 watts to 110 volts?
    From: Josieh | Date: 18/10/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, we provide such a converter. But the European standard frequency is 50Hz, and you mention below that the machine is 50/60Hz! May you confirm your machine frequency?
    Also, what is this kind of machine? Is it a motor, electronics, heater, etc?

    Connection of 10kVA frequency converter
    Doing a wiring diagram for a customer that purchased your unit a HZ-50-3310. Is the output ground connected to the input side ground internally? Are they both connected to the case? Thanks.

    Yes, both input and output groundings are connected to each other internally.
    Maximum output current capability of frequency output converter
    We need a frequency converter that can convert:
    Input 1 phase, 240 VAC, 50 hz
    To output: 1 phase, 240 VAC, 60 hz
    This is for a pilot plant that was built in the US but is using Isreali power. Pumps and other motors for the unit are on VFDs. Our Inrush current is 70A. Looks like we need a HZ-50-1120? Is that correct?

    Was this review helpful? Yes No (0/0)
    ATO Responded
    Yes, HZ-50-1120 will be okay, as long as your inrush current is 70A. Because converter max output current capability is 83.2A.
    Just the frequency converter I need
    I am seeking on a converter that will accept standard US 110/120 V 60 Hz power and output 230 V 50 Hz power for use with a 200-W instrument with a Singapore (Type G) power plug. This is all I would need the converter to be capable of. Thank you.
