#Electrical #Power #Engineering #Back #emf #magnetic Q/ Why back emf used for a dc motor? highlight its significance. Ans/ The induced emf developed when the rotating conductors of the armature between the poles of magnet, in a DC motor, cut the magnetic flux, opposes the current flowing through the conductor, when the armature rotates, is called back emf. Its value depends upon the speed of rotation of the armature conductors. In starting, the value of back emf is zero

Attend Samtec's gEEk spEEk webinar series on Thursday, April 18th @ 2:15 EST with Principal Signal & Power Integrity Engineer, at Samtec Inc. and 2020 Engineer of the Year at DesignCon, Istvan Novak, discussing how to measure low PDN impedance, a favorite choice is to use a VNA with two-port shunt-through connection scheme. This solution works well with fixtures, but when we need cables to reach the DUT, the cable braid resistance creates errors that can be orders of magnitudes higher compared to the DUT impedance. This gEEk? spEEk will explain three possible ways to suppress this error. ??

People are hyper-focused on RF and DE. Magnetic fields are the more silent killer as the focus of this field is a carcinogen like the more glamorous fields of thought whether 5g, 4g, DE, or RF. This trench was dug to run a new subpanel for powering the AC compressors, small pool equipment, and a future small subpanel to the far side of the house to minimize voltage drop. Upon completion of the panel install, the inrush current for motor startup was so fast that the visual part of the meter showed nothing compared to the previous panel having a 17 vac droop that took approximately 30 seconds to balance.?The new panel dropped 2 vac for a fraction of a second. For a sensitive person living in a structure greater than 800 sq ft, with a single panel not centrally located, voltage droop will cause elevated magnetic fields with no wiring errors causing continuous magnetic flux in the environment. Wire separation is no joke! PAY ATTENTION TO MAGNETIC FIELDS!!! #MyQuietHome #EMFMitigation #EMF #EMFConsulting #EMFSolutions #EMFSleepSolutions #EMFSafeSleep #DirtyElectricity #RF #DE

What do we really mean when we say... “Cygnus 1 Ex is Ex certified”? Read the article ?? https://lnkd.in/eJSbRCBz A vital comparison of Ex Certified equipment vs. other testing methods, e.g. MIL-STD-810G Ex certified - Equipment must be safe by design MIL-STD-810G - This is a simple test in an explosive atmosphere Ex certified - An EPL is stated, to clarify which zones it can be used in Cygnus 1 Ex is specified to Zone 0 MIL-STD-810G - The equipment is NOT Ex certified and CANNOT be taken into an Ex zone Ex certified - Multiple fault conditions are applied and considered. It requires the use of redundant safety circuits MIL-STD-810G - NO consideration for fault conditions, battery sparks, drop testing or static electric build up #excertificed #intrincicallysafe #oilandgas #inspection #exequipment #explosion #exzone #MILSTD810G Simon Moulding Steve Warner Ribu Samuel K.

Microchip has launched its second-generation Low-Noise Chip-Scale Atomic Clock (LN-CSAC), the SA65-LN, and it's a great step forward for anyone working in aerospace, defense, or systems where precision timing is key. This small but powerful device offers atomic-level accuracy and low-phase noise, all packed into a compact ? inch profile. What makes it even more impressive is its ability to operate in extreme temperatures (from ?40°C to +80°C) while consuming less than 295 mW of power. This makes it ideal for battery powered systems like mobile radar, dismounted radios, and unmanned vehicles. The integration of a crystal oscillator and an atomic clock into a single device is a game-changer. It not only ensures ultra-precise timing but also saves valuable space and power, which are two critical factors for systems that need to perform reliably in harsh environments. This could definitely simplify designs and enhance performance in projects where size, weight, and power (SWaP) are crucial.
