SEW-EURODRIVE -
VARIBLOC® wide V-belt variable speed geared motors of the VU and VZ type series are suitable for simple mechanical-engineering applications with variable-speed in the output range up to 45 kW.
VARIBLOC® VU/VZ variable speed geared motors based on SEW AC-motors are simple drives which provide infinitely variable mechanical speed control in the range up to 1:8.
Variable speed geared motors - VARIBLOC are combined with reduction gearing on variable-speed drives with a low output speed and a high output torque. The motors can also be used without the reduction gearing, in either a foot or a flange version, to drive the machine directly.
As with all SEW drives, VARIBLOC® VU/VZ variable speed geared motors can also be supplied in a wide range of additional versions, which guarantee perfect adaptation to every application.
The U-shaped or Z-shaped power flow (identified by the designations VU and VZ) and numerous swiveling positions in the variable speed geared motors in combination with the reduction gears result in a wide range of possible versions.
It is therefore possible and indeed easy to adapt them to all kinds of different machine designs.
As a low-cost drive with individual combinations of torque and r.p.m. resulting from the addition of helical-, parallel shaft helical gear units-, hell bevel- oder helical worm gear units they are mainly used in simple process applications such as those in the chemical, food and beverage, or construction materials industries and in environmental technology.
Advantages of Variable speed geared motors - VARIBLOC:
- higher starting torque
- high overhung loads of the reduction gears
- large number of high-precision reduction ratios in the gears, depending on size
- choice of manual or remote speed adjustment
- simple operation
