Engineering Data AC Servo Actuators FHA-C
Date: Jun 11, 2024Views:
Large hollow shaft with flange mounting
FHA-C Series Hollow Shaft Servo Actuators combine a synchronous servo motor, CSD Series Component Set, feedback sensor
and a specially developed output bearing.
Available in four sizes with gear ratios of 50, 100 and 160:1, the actuators can provide maximum torques from 39 to 823 Nm.
The output bearing with high tilting capacity often allows direct attachment of heavy payloads without the need for further
support, thereby providing simple and space saving design installations.
To adapt to your specific application, the FHA-C Series offers many possible combinations when selecting the motor winding,
motor feedback, brake, various sensors and cable as well as connector options.
The integrated hollow shaft can be used to feed through supply lines or services for additional axes, enabling space saving
designs with minimal installation dimensions required. The accurate positioning of the actuator ensures stable machine
characteristics, lower rejection rates and consistent quality.
By combining the FHA-C Actuators with the specially adapted YukonDrive® Servo Controllers, it is possible to provide a single
source supply for a pre-configured drive system tailored to suit your application. Alternatively, the flexible configuration of
the actuator ensures compatibility with almost any servo controller on the market.
Design and Operation
For accurate position setting, the servo motor and its control device are fitted with a measuring device (feedback), which
determines the current position (e.g. the angle of rotation set for a starting position) of the motor.
This measurement is effected via a rotary encoder, e.g. a resolver, an incremental encoder or an absolute encoder. The
position controller compares the signal from this encoder with the pre-set position value. If there is any deviation, then the
motor is turned in the direction which represents a shorter path to the set value which leads to the deviation being reduced.
The procedure repeats itself until the value lies incrementally or approximately within the tolerance limits. Alternatively, the
motor position can also be digitally recorded and compared by computer to a set value.
Servo motors and actuators from Harmonic Drive AG use various motor feedback systems which are used as position trans
ducers to fulfil several requirements.
Commutation
Commutation signals or absolute position values provide the
necessary information about the rotor position, in order to
guarantee correct commutation.
Actual Speed
The actual speed is obtained in the servo controller suing
the feedback signal, from the cyclical change in position
information.
Actual Position
Incremental encoder
The actual signal value needed for setting the position is for
med by adding up the incremental position changes. Where
incremental encoders have square wave signals, definition of
the edge evaluation can be quadrupled (quad counting).
Where incremental encoders have SIN / COS signals, then the definition can be increased by interpolation in the control
device.
Absolute encoder
Absolute encoders deliver absolute position information about one (single turn) or several (multi-turn) rotations. This infor
mation can on the one hand provide the rotor position for commutation and on the other hand possibly a reference of travel.
Where absolute encoders have additional incremental signals, then typically the absolute position information can be read at
power up and the incremental signals then evaluated to determine the rotation and actual position value.
Fully digital absolute encoders as motor feedback systems have such a high definition of the absolute value that there is no
need for additional incremental signals.
Resolution
In conjunction with the Harmonic Drive AG high precision gears, the output side position can be recorded via the motor feed
back system without any additional angle encoders having to be used. The resolution of the motor feedback system can also
be multiplied by gear ratio.
Output Side Angle Measurement Devices
Where applications place higher demands on accuracy or need torsion compensation at high torque load, the FHA-C Series
Actuators can be fitted with absolute measurement encoders directly to the
actuator output (Option EC).
