Webdynamic braking resistor current rating is known, the required rating and number of dynamic braking resistors can be determined. If a ... resistance value of the dynamic braking resistor. The following calculations are demonstrated in SI units. 2.1 Gather the Following Information 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 ...
