The RD6 device by Lika Electronic (Italy) comprises a BLDC motor, a multi-turn absolute encoder, and a position control unit. One of the communication options is CANopen.
Available in two versions with 157 W and 250 W power rating the drive is designed for applications with limited space. The 70-mm size square flange and the 14-mm shaft can be coupled with any 1- and 2-stage planetary gearboxes available in the market. The rugged anodized aluminum housing complies to IP54 protection rate.
The 24-VDC brushless motor is available in two sizes: 157-W rated power, 0,5-Nm rated torque or 250-W rated power, 0,8-Nm rated torque. Both motors feature 3000 rotations per minute. The encoder for motor feedback provides an overall 28-bit resolution (4096 counts per revolution and 65536 revolutions). It offers a real multi-turn functionality that does not require any battery or counter.
Besides the CANopen interface, there is an EIA-232 port for set-up and configuration purposes. The drive features over-temperature, over-current, over-, and under-voltage protection. It also can detect communication failures. The device implements a boot-loader, so the user can upgrade the firmware.
The RD6 rotary actuator is designed for positioning systems, change-over applications and linear guides. Typical applications include packaging lines, wood and metalworking machinery, paper machinery, material handling equipment, bending machines, filling and bottling plants, mold changers, mobile stops, tool changers, spindle positioning devices, etc.
