motors) are also covered by this instruction book. These motors have two opposed-mounted angular contact ball thrust bearings at the top end of the motor so they can carry either up or down thrust. The lower guide bearing is a radial-ball type and also carries any radial load imposed by the pump.
Poles = number of poles of your motor. So, for example, if you have a 4 pole motor on 60 Hz then RPM=60*(2/4)*60=1800 rpm. 60Hz is the most common frequency in the US. 50Hz is the most common frequency outside the US. Motors - AC VFD Drive & 3 Phase Power Training About 90
mashima can motors. mashima has advised that their magnet supplier can no longer supply magnets for future production and they are all sold out but i have inventory so motors should be available for some time. precision 5 pole motors imported by roundbell hobby products. best selection in the u s
Several types of ball mills exist. They differ to an extent in their operating principle. They also differ in their maximum capacity of the milling vessel, ranging from 0.010 liters for planetary ball mills, mixer mills, or vibration ball mills to several 100 liters for horizontal rolling ball mills.
The following equation is used to determine the power that wet grinding overflow ball mills should draw. For mills larger than 3.3 meters (10 feet) diameter inside liners, the top size of the balls used affects the power drawn by the mill. This is called the ball size factor S.

Motors of higher speed usually take a lower current than that shown in the table; while motors of lower speed usually take higher current. Wide variations from these figures can arise, especially on single phase motors, and engineers should, whenever possible, determine the actual f.l.c from the motor rating plate in each case. Single Phase Motors

Speed (RPM) = (Frequency in Hz x 120) / (# of motor poles) This would dictate that a two pole spindle motor, having a top speed of 30,000 RPM, would require a drive with the capability to provide full motor voltage at an output frequency of 500 Rz. If this motor was a four pole type, then a maximum frequency of 1000 Hz would be required.
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
