Hmmm What I get that you want to explore the affect of UHF on transformer in some way. If it is the case it means you are simulating some sort of antenna as winding of transformer will act as radiating coil depending on the frequency you are working with. Well if this is right then you can simulate it as antenna I am not sure if it will serve your
Hi, I was design a maxwell3d transient project with 2 coil a transmitter and a receiver. Transmitter fix and transmit signal and receiver have a motion and receive signal. transmitter is a coil with winding with sin current excision and 2000turn receiver is a coil with winding without excision because I (...)
Hi, your voltage calculations seem to be correct. But for safety reasons you have to consider the wire isolation, the coil winding technique (isolation layers), the winding core, clearance and creepage distances and so on.. Id say its about impossible for you to decide. But in my eyes the manufacturer should know you the answer. Maybe (...)
How to make 220-240VAC (50Hz) to 12VDC. Please tell me all the specifications i.e. no. of turns in primary and secondary, the dimensions of the core (if relevant!! current dimensions are given below), diameter of the winding coil etc.. it will be a center tapped transformer with 2 primary winding for switching purpose.. and 1 secondary (...)
How to make 220-240VAC (50Hz) to 12vdc transformer. Please tell me all the specifications i.e. no. of turns in primary and secondary, the dimensions of the core (if relevant!! current dimesions are given below), diameter of the winding coil etc.. it will be a center tapped transformer with 2 primary winding for switching purpose.. and 1 (...)
Your coil, 300mm length, 30 turns = 1 turn every 10mm. Area = width X length, you have 60 X 60 X 30, is this not a volume?. I can not make out what you are doing. Frank
Hello everyone. I intend to design a dipole coil having the specifications : 60 turns and 120 AT . I am specifying the no of conductors as 60 in the coil terminal excitation for Ansys Maxwell transient simulation. But while adding the winding, what is the magnitude of the current I should specify ? Will it be 2A or 120A. Any suggestion (...)
Hi expert! I recently built a coil with about 1500 winding of enameled wire copper, 0.2 mm of diameter. The coil was built using a DIY coil former and I use an ETD shaped core (N97 material). This is the coil (and a set of three magnets): 128477 I did some experiments by passing some magnets close to (...)
Headphones are basically small dynamic loudspeakers. I suppose you could make electrostatic ones but safety would be a serious issue. If you are planning to make the transducers yourself, start by finding a source of neodymium magnets, a good plastics molding company and a coil winding machine. Brian.
I presume you'll find the equation in your physics or electrical engineering text book. It's also derived here For 8 Hz sinusoidal flux density with Bpk = 0.5 T peak, you get Vpk = 2pi*8*0.5*n*A, n = number of turns, A = coil area
I heard people say ferrite bead is like an inductor (common mode choke) with inductance but it usually come is like discrete element(surface mount). I don't see any coil winding. No winding then how it could generate magnetic flux? Inductor is a coil winding that when electricity flow through it generate (...)
If you could find a video of how large scale multi unit coil winders work at high speed , you might understand why they don't want to reverse winding direction. Their request makes sense to me.
My motor rated current is 3a found in name plate it is rms current are peak current regards kalyan This is thermally rated for RMS, whereas Peak current will depend on load, acceleration and coil resistance, Rs. *Added 5x .. Depends on winding resistance Often this is 5x-8x steady rated current
111066 What I fail to understand is how to find if SHIELD is shorted to Point A or Point B Without Access to Secondary Transformer coil... We Have Access to Primary winding,Shield and are provided with Signal Generator
I think you connected in parallel.. 8-O Vout =32 (No load) will be higher than Vout =29 (full load ) using linear load due to internal winding loss. 230Vin/50Hz will give 29Vrms between Red-Red out at 70VA linear load or 2.41 Ohms. Nonlinear Diode/cap load causes more I?R coil losses thus you must derate 70VA load. Using PFC chip and buck re
there are 2 coils, the primary (white wires ) and secondery winding (red wires)
hi every body i wanted to know how can calculate the length of wire of coil. the copper wire winding on cylinder core (air) in N turns. the coil is not compress and there is a distance between turns. thanks and regard
There's no thing like an "allowed percentage". But a large air gap will involve increased leakage inductance and possibly additional eddy current losses in the winding. In some designs, the coil former zone around the air gap is kept free of windings to reduce this effects. Beyond "allowance", when I see a core design with unusual large (...)
Hello all, I am trying to design rod coil antenna like winding a coil to a rod, I have created a coil and tried to insert a rod in it but could not get it. Can any one help me how it can be done. Thank you in advance.
Hello guys, I have a bipolar two phase 1Ampere Stepper motor along with a driver IC. My application requires the motor to drive a load with its max power. The IC functions well but its limitation is that it would get burned if motor draws more than 0.3A per coil. KIndly suggest me what should I build to support the function of this IC without any
