The Arcflash Labs EMG-01 is a hand-held automatic 8-stage coilgun designed and manufactured by Arcflash Labs in Los Angeles, California.{{Cite web|title=Arcflash Labs|url=https://arcflashlabs.com/|access-date=2022-02-11|language=en-US}}{{Cite web|last=McCollum|first=Ian|date=2022-03-26|title=Arcflash Labs' EMG-01B Handheld Gauss Pistol|url=https://www.forgottenweapons.com/arcflash-labs-emg-01b-handheld-gauss-pistol/|access-date=2022-08-09|website=Forgotten Weapons|language=en-US}} It was the first handheld coilgun commercialized and sold as a fully assembled system.{{Cite web|last=M|first=Pete|date=2018-07-18|title=SPACE FORCE: An Electromagnetic Coilgun C/O ARCFLASH LABS|url=https://www.thefirearmblog.com/blog/2018/07/18/arcflash-electromagnetic-coilgun/|access-date=2022-08-09|website=The Firearm Blog|language=en-US}}
Operating mechanism
File:The Arcflash Labs EMG-01A.jpg
The EMG-01 uses a six-cell 25.2 volt lithium-ion polymer battery to supply up to 2000 watts of power to ten electrolytic capacitors. Unlike many coilguns, the EMG-01 operates at low voltage and does not use an inverter or capacitor charging system, which allows the system to charge in under 1/10th of a second. The ten aforementioned capacitors are used to power eight electromagnetic coils in the configuration of a linear motor to accelerate a ferromagnetic or conducting projectile to 45 m/s. Rather than fully discharging each capacitor into a single respective coil, the system uses a series of IGBTs to discharge a small portion of the total bank's energy into each coil. This system design is in contrast to many hobbyist coilguns which require several seconds or even minutes to charge a single shot, and enables the EMG-01 to fire at rates of up to 480 rounds/min.
Alpha Model
Beta Model
The EMG-01B (Beta model) was developed as a more manufacturable iteration of the base EMG-01 design. It was offered for sale in 2020 and discontinued in 2023.
EMG-02
In 2022, Arcflash Labs released a more powerful iteration with a larger bore (0.313") and 2 additional coils, with 4x the muzzle energy of the EMG-01B (up to 20J). It operates at a higher voltage than the EMG-01B; accepting 63V "flexvolt" drill batteries and featuring a single large capacitor at the rear. The EMG-02 is still being offered for sale as of 2024.
