HV ...-600 series
SyncroDyn-Servo Motors
On function concept these motors are 3-phase AC
Synchronous motors with an 8-pole permanent magnet
rotor. The patented rotor is realised as a hollow cylinder.
This unique design, together with the high coercive
strength of the rare earth (SmCo5) magnets gives the
SynchroDyn servo motors outstanding features:
High performance density at a compact axial length
High overload operating mode
High continuous acceleration
Zero cogging, even at an extremely low speed
Small start up- and stopping times
Temperature-sensor included in winding
Like a conventional AC motor, the stator coil is supplied
with sinusoidal, three-phase AC-current. At PWM control
of the circulation frequently and the terminal voltage, the
speed of the SynchroDyn servo motor can smoothly
operate between zero speed and max. noload speed.
With permanent magnet rotor, brushless, sinusoidal
commutated
Standard Version
Position feedback of the rotor through the resolver
Small electrical and mechanical time constant
Precise linearity between current and torque
IP 54 protection (IEC 34-5), type A cooling (non
ventilated), shaft run out tolerance class N, vibration
class N (ISO 2373), insulation class F (IEC 34-7), PTC
temperature sensor, shielded ball bearings lubricated for
life, separate connectors for the motor and resolver,
counter plugs included.
Options
On request, the following options and accessories are
available:
Reduced vibration class, increased protection class,
special flange, special output shaft, shorter axial length,
class S cooling, turnable connector box.
Motors are available with gearhead, rear shaft
Fail Safe Brake
For backlash free position hold of the motor shaft, the
SnychroDyn servo motor are also available with built-in
electromagnetic brake option on the mounting flange
side. The brake will act as safety brake in the event of
line failure. For opening, the brake must be connected at
DC-voltage.
