    Tips: Can a 50Hz motor run on 60Hz power source?

    The frequency is increased from 50 Hz to 60 Hz and the motor will not work properly. The main effects to the motor are:
    First, the current and output torque are reduced. The motor is an inductive load, the frequency increases, the impedance of the motor increases, and the current decreases. The output torque is also reduced.
    Second, the speed increases. The synchronous speed of the motor is proportional to the frequency of the power supply. Taking a two-pole motor as an example, the synchronous speed is 3000 rpm at 50Hz and the synchronous speed is 3600 rpm at 60Hz.
    Third, the iron loss increases. The iron loss is mainly eddy current. The eddy current is proportional to the frequency, and the eddy current increases to increase the temperature rise of the motor.

    Frequency converter recommended by ATO
    I’m trying to locate a transformer / converter that will allow US made equipment to operate in Spain. So it must meet EU specifications. Output is 200A of 460VAC – 3 PH, 60Hz.

    ATO Responded
    Yes, based on your specs, recommended frequency converter model: HZ-50-33200, 200kVA power capacity, input: 3ph, Wye (L1,L2,L3 + N,G), 380V (+/- 10%), 50/ 60Hz and output: 3ph, Wye/Delta (L1,L2,L3 + N,G), adjustable (0-520V), adjustable (40-120Hz), 277A.
    Use of frequency converter
    Do you see any issues using your frequency converter on an inverter system? Do you have data on the power efficiency of the system?
    From: Sandy | Date: 26/08/2021
    Was this review helpful? Yes No (0/0)
    ATO Responded
    1. No, no issues with using the frequency converter on an inverter system.
    2. The power efficiency of the converter is varied with loading, not fixed. But generally, its approx 80%.
    Protection of frequency converter
    I see that your converters are short circuit, and overload protected. Our country it is mandatory to also have residual current control to break the power supply. (30 mA Phase/N to ground).
    Are the N on the output internally connected to ground, or is it insulated/floating? Should it be connected to the ground externally?
    I have a residual current breaker upstream of the converter, but do I have to install a residual current breaker downstream from the converter as well?

    ATO Responded
    1. The N on the output does not internally connect to ground, it just comes from the internal transformer of the converter, and it is semi-floating.
    So normally the output N and the external ground are not connected together, but if you want to connect the external ground G to the output N at your load side, then it's okay, and no problem.
    2. If you have a residual current breaker upstream of the converter, then there is no need to install a residual current breaker downstream the converter.
    I want to buy a frequency converter
    I have a piece of kit from America (a pelaton treadmill). The treadmill requires 120v, 60hz, 12amp. We are based in the UK and run on 230v 50Hz. Could you advise of a piece of equipment that would be suitable for this please and include a price including shipping to the UK.

    I am interested in your frequency converter.
    I am interested in the frequency converter to supply historic US Jukeboxes. Could you inform me about the acoustic noise of the built in cooler?
    From: Obed | Date: 17/01/2022
    Was this review helpful? Yes No (0/0)
    ATO Responded
    It is silent, max noise generated by fan is approx 40-50 db. Also, you can place the converter 30-40m away or so and use extended wires, then no noise at all.
