TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

2021-2-17  Slip ring motors are high speed fixed speed drives (typically 6 or 8 pole motors) that are usually used for smaller mills, but sometimes for larger mills as well. They offer a low capital expenditure solution compared with other drive systems. These motors are started with a starting resistor (oil starters with stepping resistors or liquid starters). Based on the resistor characteristics a relatively smooth start is possible. This drive system is rather robust against voltage dips. However, the power factor is typically not very high and gets even lower at part load conditions. Thus, often power factor compensation is installed individually for each slip ring motor.
