HG...-600-series
SynchroDyn-Servo motors
The high speed servo motors of the HG-series are a
variant on the approved SynchroDyn-servo motors.
They were especially designed for rated speeds up to
12000 rpm.
The HG...-600 series operates with a higher rated
voltage for direct connection to servo amplifiers with
3x400 V AC supply voltage.
Due to the high power density a forced ventilation is
required to derive the dissipation heat. Therefore, the
compressed air is lead into the inside of the coil and
exits extensively on the backside of the motor.
The HG…-series correspond to a standard synchronous
motor with a 4-pole permanent magnet rotor.

Characteristics:
Nominal speed from 10.000 to 12.000 rpm
High power density by short and compact axial
length
High overload operating mode
Cooling with compressed air (no water or oil cooling
required)
Low inertia, small electrical and mechanical time
constants
Short acceleration and deceleration times

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. no load speed, in
addition high rated and maximum torques are available
over the whole speed range.

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.
