This seems like a question from an electrical course, and is probably best answered by referring to your course materials. It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
Incomplete data: To have an accurate result - please provide the following; 1. Voltage Rating - Low Votage or Medium Voltage Applications? 2. Efficiency 3. Power Factor 4. Distance - One way distance from source 5. Location and method and arrangement of Installation 6. Allowable or acceptable voltage drop 7. Type of cable - PVC or XLPE cable with same size has different ampacity
To calculate voltage drop to size the wire, a voltage must be stated.
Cable size is determined by current. You did not provide the current, nor did you include the voltage so that we could calculate the current. Please restate the question, and include either the current or the voltage.
The correct size of cable depends on the length of the cable run, as well as the voltage and current. Another consideration is what voltage loss is acceptable ? Safest answer would be to use a cable sizing table or online tool: http://www.solar-wind.co.uk/cable-sizing-DC-cables.html Hope that helps. G.
Need to know what the voltage of the motor is.
First of all find out what voltage the motor is designed to work on.
For a 37 kW induction motor, a cable size of approximately 10 AWG (American Wire Gauge) would be suitable for typical installations. However, the specific cable size required would depend on factors such as the length of the cable run, ambient temperature, and voltage drop considerations. It is recommended to consult with a qualified electrician to determine the appropriate cable size for your specific application.
For a 3KW motor with a 350-meter run and 240V supply voltage, you would typically need a cable size of around 16mm² for proper voltage drop considerations and to prevent overheating. It's recommended to consult with a qualified electrician or use a voltage drop calculator to determine the exact cable size needed for your specific installation.
The cable size depends on a few factors, such as the supply voltage, the method of starting the motor, (direct-on-line, or star delta) and the length of cable required to compensate for voltage drop. Also, if the cable is copper or aluminum.110 kW motor has a rated current of 200 amps at 415 volts, so the correct copper cable size would have a cross-sectional area of 75 square mm., if the motor is started direct-on-line.At 660 volts, the rated current would be 118 volts and the cable size would be 35 square mm.
Sir, what is the cable size for 1.5kw 3phase induction motor 400v?
It depends on the voltage that the motor needs, because a higher voltage requires less current for a given amount of power. Also a higher voltage can tolerate a higher voltage drop. So there are two things that lead to a thinner wire when the voltage is higher.
To answer this question the voltage is needed.

just apply the formula :-p=v*i*cos(angle);now you have the power rating,load so in turn power factor so you can easily calculate the value of current.with the help of current you can chose the cable available in the market either the aluminum or copper wiresatendra.svnit@gmail.com
