The difference between low voltage and high voltage for the same size cable is that cable size affects current carrying wave winding is used for low current and high voltage motors. Breaking down the basics of electrical motors posted on april 16, 2018 by kurz industrial solutions you may not realize that electrical motors are part of daily life for nearly every person in the world. However, in the last 50 years most standards called for ratings of 115, 208, 230, 460 and 575v, representing a 5 percent drop from distribution. Prior to 1965, the national electrical manufacturers association (nema) recommended nominal motor nameplate voltages of 110, 208, 220, 440 and 550 volts (v), which are approximately 10 percent below standard distribution voltage. You would wire it high voltage if you were supplying 460v. This is not the case see graph below. This is not the case. 3 phase high and low voltages. Above 1000 hp it is difficult to find motors that are not wound for medium voltage. The supply voltage to the vfd) and the horsepower rating. It has a higher voltage battery. Bft automation products with 24v technology offer several advantages compared to high voltage motors (230v): As in if you have a 230460v motor the high voltage connection is for 460v incoming service.
The different connections for low and high voltages are made inside the junction box instead of the box on the side of the motor. Usually its speed is not very high, but high torque output. Motors rated 200 hp and above are often wound for medium voltage (2300vac or 4160 vac) instead of low voltage (480 vac to 600 vac). Voltage drop from the network to the motor terminals, motors are designed with a 10% tolerance for voltage above and below the rated nameplate value. Since the motor is a 230/460, and you have a 208v supply, you would wire it low voltage.
Wiring Motors High Or Low Voltage Electrician Talk from www.industrial-electronics.com The rule of thumb for motors is. This is when the motor leads are connected in low voltage configuration. High voltage motor wiring diagram to control high voltage or high power we will turn on a 12v motor using a relay. Difference between low voltage/ high voltage on a marathon motor / differences between earthed and unearthed cables : Motors rated 200 hp and above are often wound for medium voltage (2300vac or 4160 vac) instead of low voltage (480 vac to 600 vac). Since the motor is a 230/460, and you have a 208v supply, you would wire it low voltage. Voltage drop from the network to the motor terminals, motors are designed with a 10% tolerance for voltage above and below the rated nameplate value. Typically, the voltage level between the 220kv to 760 kv is called extra high voltages.
This is not the case.
The different connections for low and high voltages are made inside the junction box instead of the box on the side of the motor. Isolation procedures are more involved 5. So, let's say that electric mower a has a 48v (voltage) battery and a 1.7kw (power) motor. This is the pigtail that connects the motor to the power source. The power drawn by the load = p (mechanical) the power drawn by motor (electrical) = p / motor and the drive system efficiency so may be just a few percentage more than it.say 1.1p (ie 10% more) this electrical power = voltage x current x power factor. But rising demand for power due to heavy consumers on new ships require an efficient and surplus power supply. Now, if i connect the motor leads in high voltage configuration to 230v power, all is dandy. High voltage systems are more extensive with complex networks and connections, 2. Your motor is now wired for 120 volts. Low voltage vs high voltage motor scottyuk (electrical) 29 sep 17 17:30 400hp is really at the breakpoint between voltage levels, so as bill says you could choose either option and not be 'wrong' , but the decision may be made by other factors such as availability of an existing mv network. These devices make life easier. Here are a few assumptions to help simplify the discussion: The difference between low voltage and high voltage for the same size cable is that cable size affects current carrying wave winding is used for low current and high voltage motors.
Voltage drop from the network to the motor terminals, motors are designed with a 10% tolerance for voltage above and below the rated nameplate value. This is not the case. Motors are everywhere, from the car that you drive to work to the lawnmower in the garage. Improved movement control, better performance in. It has a higher voltage battery.

Above 1000 hp it is difficult to find motors that are not wound for medium voltage.
Effects of high voltage* one of the basic things that people assume is, that since low voltage increases the amperage draw on motors, then by the same reasoning, high voltage would tend to reduce the amperage draw of the motor. This high voltage or extra high voltage level is maintained to transmit the power to a long distant substation. Now, if you believe the bigger is better myth perpetuated by some manufacturers, electric mower b is the better choice. Prior to 1965, the national electrical manufacturers association (nema) recommended nominal motor nameplate voltages of 110, 208, 220, 440 and 550 volts (v), which are approximately 10 percent below standard distribution voltage. Electric mower b has a 72v (voltage) battery and a 1.7kw (power) motor. An assumption people often make is that since low voltage increases the amperage draw on motors, then high voltage must reduce the amperage draw and heating of the motor. Even with the small range of motor ratings, there are more than a few variables. This is the pigtail that connects the motor to the power source. Since the motor is a 230/460, and you have a 208v supply, you would wire it low voltage. The power drawn by the load = p (mechanical) the power drawn by motor (electrical) = p / motor and the drive system efficiency so may be just a few percentage more than it.say 1.1p (ie 10% more) this electrical power = voltage x current x power factor. The major differences between high voltage supply and low voltage supply on board ships are: The low voltage connection isn't quite so obvious. Sometimes you apparently need to rewire a 3 phase motor for low voltage 230v as opposed to 460v in order to connect the motor to a vfd.
