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 |
