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.
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 .
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 .
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.
Explained that in the past, grinding mills operating between 18mw and 28mw required a large electrical wrap-around motor, known as a gearless mill drive gmd the qdx4 mill drive system is an alternative option to the gmd until now, the gear-driven solution for large sag and ball mills was limited to 18mw.

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.
The first gearless mill drive gmd with a power of 6.5 mw was installed 1969 in a cement milling process in the cement plant le havre in france. in the first few years, the gmd was only used in the cement industry. the gmd is also known as wrap-around motor or ringmotor. almost 25 years later, the first gmd with 12.0 mw power.
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.

Large synchronous motors are often used in the mining industry to run mills. these applications tend to span from about 400hp 300kw to twin 7,000hp 5.2mw x 2. as someone else noted, by over-exciting the field windings of these motors, they can.
Having fabricated the table and the pulleys, i disassembled the original setup. i installed the lathe onto the new table with the four steel stand-off pillars and affixed the motor onto the motor mounting board. the clearance provided allows me to clean out chips very easily, and a lot of room to wrap my fingers around the cross slide dial handles.

Gearless motors up to 22 mw are in service in many of these ore processing plants gearless motor drives are also known as ring motors or wrap around motors the motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill this is similar to the rotor of a conventional motor.
Sag mill wrap around motor wraparound sag mill failure - , matching real world results all of the ore processed wraparound sag mill failure by the mine passes through the primary sag mill performance of the latest generation wrap-around motor-driven, large grinding mills that it .
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.
