| Compact spindle
servomotors. Based on flux concentration
technology and controlled by the DIGIVEX Drive range, the HV
synchronous servomotors are designed for the spindle
motorisation of conventional machines.
Developed by Parvex, this technology enables a range of
constant power to speed ratio of up to 10 to be covered. And
the HV motors have dynamic characteristics equivalent to
axis servomotors : very high mass to torque ratio, low
inertia, high torque at standstill ...

 High
torque/weight ratio for increased machine compactness
Low inertia
for rapid changes in speed
Exceptional
regulation at low speed
Wide speed
range at constant power : ratio up to 10
High torque at
standstill
Possibility of positioning for tool changes

Examples of
applications
Because of
their high dynamic qualities and their compactness, HV
spindle motors are suitable for the motorisation of high
performance spindles (lathes, milling machines,
grinders,…).
They are
controlled by the DIGIVEX Drive range which provides
them with all their qualities and flexibility of use.
Synchronous spindle technology is also available for
electrospindles with the HW range. |

A range suited to your
needs
The HV motors are available for :
Torque from 17 to 240 Nm (150 to 2110 in-lb.)
Speeds up to 8000 rpm
Power from 3 to 45 kW (4 to 60 hp)
These
motors use flux concentration technology which enables
the construction to be more compact and more robust.
They are characterised by constant torque at low speed,
and constant power over a wide range of speeds (1:10),
achieved by DIGIVEX Drive.
Their low inertia enables greater acceleration for
reduction of tool change time and more rapid cycles |
