Note that modern wrap-around gearless mill drives do a software correction to report mill motor output power which is the same as shell power.Therefore, new gearless mill drives do not require any correction when comparing dcs power measurements to model power draw predictions.Power predictions are only valid below motor rated speed.Get Price List
Wrap-around motor or ringmotor.The motor rotor is composed of individual poles mounted on the mill flange.The number of poles is based on the required speed of the mill.Thus, the sag mill motor has 72 poles and the ball mill motors have 56 poles.Excitation transformer and excitation converter with full wave control.

Alternative names wrap-around motor and ring motor see figure 1.Its purpose is to generate a magnetic field in the air gap turning exactly with the desired speed of rotation of the mill.The electrical three-phase winding of the stator is supported by the stator frame.Depending on the size of the mill, the stator can be of the.
Field in the air gap of the motor, eliminating the gear reducer, the ring-gear and the mechanical related issues faced by maintenance with ring-geared mills.In fact the rotor of the ring motor is the mill itself and the stator is built around the mill shell.This is also the reason why the ring motor is also known as wrap-around motor.9 12 6.
Mills.In fact the rotor of the ringmotor is the mill itself and the stator is built around the mill shell.This is also the reason why the ringmotor is also known as wrap-around motor.Drive technologies in the not too distant past, variable speed solutions were.
The motor air gap, distance between poles and stator frame, is defined together with the mill manufacturer and need to be ke pt in the range of 16 mm.The stator frame is designed as a.
Mark the platform just above where the motor arm ends and cut a long, narrow slit that is just wider than the width of the belt.The belt will be connected to the motor that will be mounted underneath the platform.It will be fed through the slit to wrap around the container and cause it to spin.
Fleet farm has been proudly serving the upper midwest since 1955 with high quality merchandise you wont find anywhere else.We are your full-service supplier for life, work, home, and recreation - combining wide-ranging products, convenient.
By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.The gearless motor - also called wrap-around motor or ring motor - is a very large synchronous machine which uses power electronics and a magnetic field to control the speed of the motor rotation.
