http://dynamicbrake.com/dynamic-brake-calculator/ WebBraking Resistor Calculator from KWK allows you to calculate Continuous & Braking Power from Known Motor Power. To calculate the right size of the resistor you need the data of the load cycle: brake time or duty cycle …
Web2) Total Resistor Power; is decided by the energy to be returned from the load and the motor size. Rule of thumb is - a typical horizontal conveyer or similar load required to stop occasionally and can stop in less than 2.5 seconds at full braking, will need a resistor continuous power just less than 10% of motor power.
