Good day Noble Minds,
I need a fast switching SPDT relay(not less than 1Khz) to implement the circuit below.
Both S1 switches will close to terminal 1, when both S2 switches close to terminal 2 and vice versa.
Your recommendation of any available module in the market will be highly...
Does anyone know where I can get any of these inverter power supplies for use in Electrical/Electronic laboratory?
1. Power :1KVA
Wave Type: pure sine wave or modified sine wave:
Voltage Output:220V
Frequency range: 5Khz to 1Mhz
2. Power :2KVA
Wave Type: pure sine wave or modified sine wave...
Hello Great Minds!
1. I need a quality AC power supply with a phase angle control. I bought an SCR power supply but the output is not good enough at all for my project.
I get as much as 40V output when the SCR is not fired while applying a voltage of about 240V at the input. I need output of...
Hello Everyone,
I need information on how to design a PM generator and have the rotor turn freely, without too much cogging from the forces due to the strong neodymium magnet.
I have several diverging information from my research and need to be sure of what I am doing. Generally, there seems...
What is the inductance of the coil?
I need to determine the current I, flowing through the coil. I=V/Z. Z is impedance of the coil.
Assuming the resistance of the coil is negligible compared to its reactance. Then I=V/X. X=2*pi*f*L where pi=3.142, f=50Hz. thus I=V/(2*pi*f*L)
Now, how do I...
We have several number of UPS systems in my large facility. The UPS systems are of SAFT and use Ni-Cd alkaline batteries which are all arranged in standard insulated racks.
We have experienced a common problem across these UPS systems, and that is earth fault. This was traced to the battery...
I have about 60A of current flowing in a 300 turn coil. I need the magnetic flux from this coil totally trapped in a soft iron or Mumetal or Metglas or any other soft magnetic material that is affordable.
So I would wrap the coil toroidally around the soft magnetic material. Now I designed with...
Hello Everyone,
Please I need recommendations for the affordable commercial motors to be used, given below specifications and required functionalities.
First Case
1. Torque of inertia weight to be driven(load) and all opposing torque will vary from 1Nm to 4Nm.
2. Constant speed of revolution...
Hello good people!
I would appreciate if anyone could help me with a circuit available in the market that can help me realise the drawing attached.
The purpose of circuit is to keep the electric motor speed constant as the mechanical load on the motor keeps varying.
What electrical circuit...
