Cycloconverter control of induction motor drive has applications in high power drives requiring good dynamic response but only low speed operation eg in ball mill in a cement plant the low speed operation is obtained by feeding a motor with large pole numbers from a cycloconverter control of induction motor operating at low frequencies.
Variable frequency supply to an induction motor may be obtained by using a cycloconverter as has already been discussed a cycloconverter is a single stage frequency conversion device which converts ac line frequency to a variable frequency a cycloconverter feeding three phase induction motor drive is shown in fig 421.

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 simine gearless mill drives pump system significantly enhances concentrator productivity by eliminating the reducer gear between motor and pump and all corresponding maintenance in addition the cyclone pumps with variable speed can adjust their energy consumption to the optimized flow of pulp resulting in energy savings of up to 30%.
The ft range of induction motor includes ftcftcv type squirrel cage and ftaftav type slip ring motors - ftcfta types are horizontal and foot mounted (im b3 iec60034-7) machines whereas ftcvftav types are vertical flange mounted (im v1 iec 60034-7).
An induction generator is a type of asynchronous generator meaning the waveform that is generated is not synchronized to the rotational speed permanent magnet generators are simple and reliable and can work at low speeds so they are ideal for use with wind turbines.
An induction motor or asynchronous motor is an ac electric motor in which the electric current in the rotor needed to produce torque is obtained by electromagnetic induction from the magnetic field of the stator winding an induction motor can therefore be made without electrical connections to the rotor an induction motors rotor can be either wound type or squirrel-cage type.

Mar 09 2016&0183;&32;wiki : "universal motors are best-suited for devices such as food mixers and power tools which are used only intermittently and often have high starting-torque demands" i thought about fan or water pump motor (induction motor) unfortunately the torque will not be enough to drive the full load i will also need pulleys to reduce the speed.
Sep 24 2014&0183;&32;it may not be as simple as a 1:1 hp replacement you really have to analyze the torque-speed requirements of the ball mill before making that decision a vfd on a standard induction motor is good at making sure the motor can supply a constant level of torque regardless of speed.
