Its been a while since ive brushed up on my electricity knowledge, but im fairly certain that breaker capacities are based on amps. I think you would have to know the amperage of the motor before you were able to conclude what size you need.
I have used several hundred ABB drives. The term "VFD" is just another name for a "drive". It stands for Variable Frequency Drive. A "VFD System" is an electrical power control system, for example running a pump, in which the drive varies the speed of the pump motor. The drive does this electronically using pulse-width modulation to vary the average motor power frequency. When the motor sees 30 Hz instead of 60Hz, the motor runs 50% speed.
The one with the output of 5v 800ma as this will charge devices quicker and overheat less.
An electronic component of floor lamps sold by Home Depot that have a two-bulb 120v fixture on the top and a single bulb 12v fixture on a flexible arm. These may not be very reliable as the circuit board failed on mine in less than two years of light-duty service.
Typically computers are connected to a UPS. Rarely they are connected to direct power supply. The UPS may provide 110V or 220V supply oscillating at 50Hz and 60Hz. These values depend on the particular country's power supply standards. The electricity supply then goes to SMPS in case of desktops. SMPS is a control circuit that switches the load current rapidly on and off in order to stabilise the output voltage. Typically different components get different levels of voltages. It may range from 1.5V to 12V. Note that computer components run on DC supply not AC supply so it is converted by SMPS. In case of laptops the AC supply is converted to DC and then given to battery which further supplies the laptop components.
If you are epileptic try taking a break every 10 -15mins because of the rate computers flash per second. You can check how many time it flashes by the mod code. There are 'screens' that show less of how many times computers flash a second. Older CRT monitors with low refresh rates (lower than 60Hz) can be prone to flickering. You may be able to increase the refresh rate of your monitor by changing the settings on your operating system. If your CRT monitor does not support a refresh rate higher than 59Hz, you may want to consider switching to a LCD monitor which are much less prone to flickering. For a LCD monitor, some people may notice flicker on certain monitors while most other people would not. This can be hit and miss. If you experience this problem, try going to a store and testing out display LCD monitors for flicker.
25 amps and it should be run through a contactor and motor over load set,you should set the over load to 5% above the motors full load current.And not your breaker should be a d curve type with 6ka rating.
Not really because motors are designed to run at either 50 or 60 Hz and the wrong frequency might cause them to malfunction or overheat.
You don't.
I'm looking for a replacement motor for Emerson k55hxjbr-8989 1/8
The power supply for the Sunpentown WA-1340DH Portable Air Conditioner/Heater Combo is 115V / 60Hz.
One way would be to hook it up to a supply (by itself, with no load) and measure the speed with a contact tachometer. If your supply is 60Hz, and the motor speed corresponded to one of the standard motor speeds, it would be a pretty safe bet you had a 60Hz motor. If the speed was about 20% faster than a standard speed, the motor is probably a 50Hz motor. Or 20% slower if you were running a 60Hz motor on 50Hz For instance, a 1750 RPM 50Hz motor would spin at about 2100 RPM if you ran it on 60Hz.
What effect will be there on the motor (Induction) output power when a 100kW 50hz motor is connected to a 60hz power supply.
The the supply stays within +/- 5% of what the motor is rated for, you can do this.
The motor will run, probably at nearly the same speed, but it cannot supply the same mechanical load. If it can be run on a lighter load, proportional to the voltage, it should be OK.
Yes, most VFDs can run faster than the input power frequency so you can run a motor to 60Hz with a 50Hz power source. Just be aware that as speed increases, so will the current. Also be aware that a motor is rated to run a specific rpm and running faster may cause motor bearing failure after a short time.
Yes. It will make your motor a little faster though, so it depends on what you are powering with this motor. IE Can the piece of eguipment be ran faster?
It will not work at all.
