RD6, the gearless rotary actuator for efficient
positioning operations
RD6 is the first positioning actuator without gears in the ran-
ge of Lika Electronic. The 70 mm size square flange and the 12
mm shaft are designed to be coupled with 1- and 2-stage planetary
gearboxes available in the market. The unit can be easily integra-
ted in customized applications to meet specific torque and speed
requirements.
RD6 features a space-saving design with rugged anodized alumi-
nium housing for high IP54 protection rate and installation in typi-
cally industrial environments.
The compact enclosure integrates a BLDC motor, the real multiturn
absolute encoder, the position and torque closed-loop controller
and the fieldbus interface. The 24Vdc brushless motor is available in
two sizes: 157 W rated power, 0.5 Nm rated torque and 3,000 RPM;
250 W rated power, 0.8 Nm rated torque and 3,000 RPM.
The encoder for motor feedback provides an overall 28-bit resolu-
tion (4096 counts per revolution and 65536 revolutions) and fea-
tures a real multiturn that does not require any battery or counter.
RD6 is versatile and open thanks to the integration of the Profi-
bus-DP, CANopen and Modbus RTU (RS-485) fieldbus interfaces.
Furthermore it is up-to-date and can even provide the most popu-
lar Ethernet interfaces: EtherCAT first; Powerlink, Ethernet IP and
Modbus TCP the coming months. The integrated RS232 service in-
terface allows easy set-up and configuration. RD6 further includes
overtemperature, overcurrent, overvoltage, undervoltage and bus
communication failure and implements the boot-loader feature in
all models, so the user can easily upgrade the firmware when a new
release is available. RD6 rotary actuator is designed to drive positio-
ning systems, change-over applications and linear guides.
Typical applications are packaging lines, wood & metalworking
machinery, paper machinery, material handling equipment, ben-
ding machines, filling and bottling plants, mould changers, mobile
stops, tool changers, spindle positioning devices and any equi-
pment where you need to cut machine set-up times and reduce
downtimes.
Available in two sizes with 157 W and 250 W power rating and a wide range of bus and Ethernet
interfaces, RD6 rotary actuator integrates a BLDC motor, the real multiturn absolute encoder and
the position controller in a single compact and low price unit.
