Self Controlled Synchronous Motor Drive Employing a

Self Controlled Synchronous Motor Drive Employing a Cycloconverter: A typical rating of a synchronous motor for a ball mill in a cement plant is: 8750 hp, unity power factor, 14.5 rpm, 4.84 Hz, 1900 V and 40 poles. A cycloconverter is ideally suitable for such a low frequency supply. Earlier gears were employed to get low speed operation. Absence of gears in this drive reduces the cost and

Synchronous motor Wikipedia

Type. Synchronous motors fall under the more general category of synchronous machines which also includes the synchronous generator.Generator action will be observed if the field poles are "driven ahead of the resultant air-gap flux by the forward motion of the prime mover". Motor action will be observed if the field poles are "dragged behind the resultant air-gap flux by the retarding torque

When should you choose linear motors vs ball screws

While ball screws typically use a rotary encoder mounted to the motor for positioning feedback, linear motors use a magnetic or optical linear scale for position feedback. The linear scale measures position at the load, which gives a more accurate reading of the actual position. For very high-precision applications, this more accurate position feedback can mean the difference between a part

Gearless mill drives Grinding ABB

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor. The motor is fed by a fuse-less cycloconverter that is connected to the MV network through three special cycloconverter
