Motors and sensors go hand in hand. The EX range of motors already feature a wide range of sensors that deliver feedback on various parameters and, now, Parker has added a HIPERFACE DSL® encoder to the EX range of motors with explosion-proof enclosures. This makes it even simpler to control and monitor the EX servo motors using a Parker Servo Drive controller.
The High Performance Interface Digital Servo Link protocol runs on a standard RS485 connection to add the level of robustness needed to use it in almost any application. This includes industrial machinery, robotics and chemical and waste processing plants.
The main benefit of this technology is that it uses just one cable to deliver all of the motor control functions. This cable, which can be up to 100m long, can be bundled with the power cable, making it simpler to provide power and control to machines, robots and other equipment. With just one, smaller cable required, the umbilical for industrial machinery is lighter and more flexible, making them more reliable while delivering greater freedom of movement.
The EX motors, now equipped with the HIPERFACE DSL® interface, feature an explosion-proof enclosure and are certified for use in explosive atmospheres (CE/ATEX and IECEx). This includes use in atmospheres where explosive gases or dust are present.
As only one cable is needed, the EX motors have a lower total cost and provide a more reliable solution than a motor that requires two connections for control and feedback. These permanent magnet motors have a torque range of 1.75 to 35 Nm and come with a 2-pole resolver as standard and now an optional HIPERFACE DSL® encoder. This offers up to 20-bit resolution per revolution and a maximum of 4,096 revolutions in a multiturn system. Thermal protection is covered by the thermoswitches and thermofuses that are integrated into the motor's windings.
EX motors are compatible with the Parker Servo Drive (PSD) series, providing a complete solution for motor control in ATEX applications.
We can also offer a complete drive solution for ATEX applications with ETH the actuator and GXA gearbox (ATEX).
Finally, Parker’s well-known ETH electro cylinder range for the explosive atmosphere is certified for use in explosive gas atmospheres (device group II, category 2G).
