RD6 is a compact rotary actuator from Lika Electronic that integrates a BLDC motor, an absolute encoder, and control electronics in a single package. 

Increasingly, modern industries require automated production processes with little downtimes to ensure efficiency, provide precise control and repeatability, increase productivity, and improve product quality. Meanwhile, the “large batch, long run” philosophy is becoming obsolete because volatile demands call for quick responses today. Small batches, one-off items, just-in-time production, and the acceleration of cycle times often drive businesses.

Rotary actuator for positioning operations RD6 is a compact rotary actuator from Lika Electronic that integrates a BLDC motor, an absolute encoder, and control electronics in a single package. It is available in two sizes with 157-W and 250-W power ratings and CANopen. The RD6 rotary actuator is Lika Electronic’s most complete, powerful, and up-to-date solution developed to help the modern industries solve these tasks. It is designed to drive positioning systems, changeover applications and linear guides, and allow to reduce set-up and change-over times, as well as ensure maximum efficiency and precise repeatability.

The positioning actuator without gears was developed to make positioning operations more efficient and powerful, so production processes can benefit from faster adjustments, shortened downtimes, and reduced risks of errors and waste. Its “all-in-one” configuration with embedded intelligence provides the user with a simplification of design and integration.

The actuator features a space-saving and rugged anodized aluminum housing capable of IP54 protection for installation in typical industrial environments. The 70 mm size square flange and the 14 mm shaft are designed for coupling with standard planetary gearboxes. Thus the unit can be integrated into custom applications to meet specific torque and speed requirements. The compact enclosure integrates a BLDC motor, a real multi-turn absolute encoder, a position and torque closed-loop controller, and a fieldbus interface. Its advantage is its simple installation while the cabling operations are reduced to a minimum, saving time and money. The 24-VDC brushless motor is available in two sizes: 157-W rated power, 0,5 Nm-rated torque, 3000 RPM; or 250-W rated power, 0,8-Nm rated torque, 3000 RPM. The builtin encoder for accurate motor feedback provides an overall resolution of 28 bit (4096 counts per revolution and 65 536 revolutions) with a position accuracy of ±0.9° and features a real multi-turn that requires neither battery nor counter.

The rotary actuator is designed to drive positioning systems, change-over applications and linear guides. Typical uses are packaging lines, filling and bottling plants, food processing and pharmaceutical industries, material handling equipment, conveyor systems, wood and metalworking machinery, paper machinery, bending machines, printing machines, mold changers, mobile stops, tool changers, spindle positioning devices, and any equipment where you need to cut machine set-up times and reduce downtime.
