What happens if ice gets between stator and rotor?

Ice is electromagnetically transparent and therefor will not affect IncOder’s inductive measurement technique. A light surface frost will have no effect but a heavy frost which might mechanically bind the stator and rotor together may cause damage when the rotor begins to move. If there is a possibility of heavy ice between Rotor and Stator then select Extended Range Product Option ‘C’. More generally, it would be good practice to provide mechanical protection against such heavy ice.
