Selecting Inching Drives for Mill and Kiln Applications

The standard inching drive motor is a NEMA or IEC frame typically foot mounted to a motor scoop or base plate. Typical motor speeds are either 4 or 6 pole, i.e. 1750 rpm or 1170 rpm for 60 Hz applications and 1450 rpm or 970 rpm for 50 Hz applications. The advantage of using a four pole motor allows for a smaller footprint and a smaller brake if
