Technical Data

Brushless Hollow Shaft-Actuator

HollowDyn
HWM...-600 series
Hollow shaft actuators
The hollow shaft actuators HWM...-600 are a special
variation of the approved Printed Motors SynchroDyn –
actuators. In principle, these motors correspond to 3phase synchronous motors with a 8-pole permanent
magnet rotor.
The use of rare earth magnets with a high energy
product and a special guidance of the magnetic flux
through the superficial parts of the rotor, the inside can
be designed as a hollow shaft with a huge drilling.

Characteristics
High power density by short and compact axial
length
Throughout hollow shaft with inside diameter up to 80
mm
With permanent magnet rotor, brushless, sinusoidal
commutated
Zero cogging, even at an extremely low speed
low inertia, small electrical and mechanical time
constants

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, in
addition high rated and maximum torques are available
over the whole speed range.

Short start up- and stopping times
High overload operating mode
With integrated resolver or hall sensors
Nominal speed 3000 to 5000 rpm
Deliverable with hollow shaft gearboxes up to 400
Nm

The rotor position is seized by a brushless resolver.
Through its sine und cosine-signals, the current angle of
the rotor and the rotation speed are reported to the
servo-amplifier, so no additional position sensor is
needed. The hollow shaft resolver is integrated in the
rear side of the servo motor.
