How do you measure the air gap? Electric motors

Jul 31, 2010If rotor iron runout is small for example 0.002, then probably the stationary test is good enough. If rotor iron runout is 0.005 (as is common for our very large motors), then you see the rotor TIR is on the same order as the 10% airgap acceptance criteria tough to ignore it imo. At any rate, it was a good clarification.
