Greetings....I have a customer that had some significant mechanical damage to ice machine hut, specificaly a motor/gearbox ice rake chain assembly.
During a poco outage and single phase condition, the customer is claiming that the motor and a 1:100 !! gear reducer recoiled enough mechanical energy to back spin and actual run backwards on single phase power when it was ran manualy by the owner while trying to troubleshoot , thus overiding overload protection. While I see this as a possibility with the extreem leverage of a 1:100 reducer, I still question if enough torque would be present to do this much damage. It twisted a 1in 316 S.S. shaft like it was butter and the customer had to pay nearly $5k in parts not to mention loss of biz........now the customer is wanting me to defend him in his claim against poco. Im saying..Nah.....any comments? thanks....Mule
