## Overview

The OpenGrab EPM V3 R5C is a cutting-edge electropermanent magnet that combines the power of a 475 V high-voltage pulse with ultra-low steady-state power consumption (under 50 mW). It reliably holds up to 20 kg without continuous electricity, supports multiple control protocols including UAVCAN and RC PWM, and is designed for UAV cargo lifting, robotic workholding, and educational demonstrations. Lightweight at 97 g and fully open-source, it’s engineered for professionals pushing the boundaries of magnetic tech.

## Description

NicaDrone OpenGrab EPM v3OverviewThe OpenGrab EPM v3 is an electropermanent magnet, combining the advantages of electro and permanent magnets. The device creates a very strong magnetic contact with a ferrous target. It supports UAVCAN, RC PWM and push button operation. ˃˃˃ Theory of operationThe NXP LPC11C24 MCU drives a mosfet connected to a transformer in a flyback configuration to charge the main PET capacitors up to 475 V.A thyristor bridge is used to discharge the capacitor in either direction through the winding inside the AlNiCo material. This results in a short, 20 us 300 A pulse creating a 100 kAm field in the AlNiCo material. This causes the magnetic domains in the AlNiCo magnets to align in a particular orientation to form a magnetic circuit with a ferrous target. More detailed explanation of the operating principle is available on Wikipedia.An ON command results in the charging and discharging the capacitors 3 times to achieve full magnetization.An OFF command results in charging and discharging the capacitors several times with changing direction and decreasing amplitude, effectively degaussing the AlNiCo material.˃˃˃ ApplicationsCargo lifting in UAV and robotic applications.Robot workholding.Education, demonstration of magnetic properties.FeaturesSteady state power under 50 mWShort cycle time˃˃˃ Documentaion / LinksSource repository (firmware sources, drawings, etc)https://github.com/Zubax/opengrab_epm_v3PCB layout and schematichttps://upverter.com/ctech4285/1dada3422c772add/OpenGrab-EPM-V3R3/Purchase from NicaDronehttp://nicadrone.com/index.php?id_product=66&controller=productDocumentation https://docs.zubax.com/opengrab_epm_v3#Mode_and%20status%20codes
