Precision FG Drives
Direct March Towards Large Steps in the Number of Revolutions
Our FG precision drives are tough to crack. They are extremely immune to vibrations and high ambient temperatures. The precise gear is made up of a main motor and another precise gear that are linked together through a precise gear reducer. In this way it is possible to make large steps in the number of revolutions in a robust, simple and cost-effective way.
Description
At the same time they allow:
- Maximum positioning precision
- High connection frequency
- Movement of large masses in a reduced cycle time
- Realization of extremely high steps in the number of revolutions up to 500: 1

A Robust Alternative to Inverter Controlled Three-Phase Current Motors
Big Difference in the Number of Revolutions
- Steps in the number of revolutions up to 500: 1
- Greater mechanical difference in the number of revolutions between the main speed and the positioning speed than with pole-switching motors.
Up to 4 Fixed Steps in the Number of Revolutions When Using Pole-Switching Motors
Short Cycle Times
Maximum Positioning Accuracy
Technical Data
Base Designs:
- FG precision drive with main and precision motor (connected to each other through a precision reducer):
- The drive shaft rotates with the number of revolutions of the main motor or precision motor (reduces the reduction ratio of the reducer).
- Conical rotor brake motor as main motor (due to the axial movement of its rotor)
- The motor brake acts as a coupling in the precision motor function.
- The precision motor may optionally be a KB or Z motor, also in the inverter function.
- A finely stepped reduction of the precision reducer from 4 to 125
- Together with the selected engine revolutions, the total reduction ratio is thus selected
- U and Z design finishes
- In the coupling version, the precision drive can be combined with the flat, angle and spur gear reducers of the Demag modular system
