WebThe AKD2G Safe Dynamic Braking calculator is a tool that will assist you in determining the Stopping Time for the motor when using the AKD2G’s Safe Dynamic Brake ( SDB) function. In some applications, it will be beneficial to short the motor wires via “Safe” relays rather than using an electromechanical holding brake. WebSep 21, 2024 · 1 2. P = t * w, where 'P' is power (in Watts), 't' is torque (in Nm) and 'w' is rotational speed (in rad/sec). So start by figuring out how much power the brake resistor will be dissipating. Then you can use P = V^2/R. For 'V' use the back emf of the motor at the fastest speed you need to brake at. You can calculate the back emf using the KV of ...
