Positioning Drive

Festo’s EMCA positioning drive provides a compact, easy-to-install, integrated drive system for a wide array of automated manufacturing applications. EMCA consists of a maintenance-free, wear-resistant, brushless DC motor with built-in power and control electronics, all in a rugged housing. That dispenses with the need for long motor cables, improves electromagnetic compatibility and requires less space than comparable setups using separate components, while its built-in monitoring functions ensure safety and reliability. The positioning drive is equipped with a 24 V DC power supply and senses absolute position using a single-turn encoder or optional multi-turn displacement encoder for up to four billion revolutions. EMCA is available in two motor lengths and power classes, and can deliver peak torque of up to 0.91 Nm, with a maximum rotational speed of 3,500 RPM and peak power output of up to 200 W. The motor housing provides IP54 degree of protection as standard, with IP65 available as an option. EMCA also supports “safe torque off (STO)”, ensuring there is no risk to the user’s system from the motor continuing to rotate in case of emergency. The EMCA can be controlled via fieldbuses including CANopen, Ethernet/IP and I/O-Interface, with EtherCAT and PROFINET pending.
