How to make motors safer and easier to operate in explosive atmospheres

Motors and sensors walk hand in hand. To the EX range of motors, already equipped with a number of sensors capable of providing feedback on various parameters, Parker has now added a HIPERFACE DSL® EX range of motors encoder with explosion-proof housing. Thus, controlling and monitoring EX servomotors through a Parker servo controller is even easier.

The High Performance Interface Digital Servo Link protocol operates on a standard RS485 link, giving it the robustness needed for use in almost any application. This includes industrial machinery, robotics, and chemical and waste processing plants.

The main advantage of this technology is that it uses only one cable for all motor control functions. The cable, whose length can be up to 100 m, can be combined with a power cable, a feature that makes it much easier to provide power and control machines, robots, and other equipment. As only one cable is needed, and it is also smaller in size, the umbilical cable of industrial machinery is lighter and more flexible, thus ensuring greater reliability and freedom of movement.

EX motors, now equipped with the HIPERFACE DSL® interface, feature explosion-proof housing and are approved for use in explosive atmospheres (CE/ATEX and IECEx). This means that they can be used in the presence of explosive dust or gases.

Requiring only one cable, EX motors boast a lower total cost of ownership and are more reliable than motors that require two different connections for commands and feedback. These permanent-magnet motors have a torque range of 1.75 to 35 Nm; they are also equipped with two-pole resolver as standard and now with optional HIPERFACE DSL® encoder. A resolution per revolution of up to 20 bits and a maximum of 4,096 revolutions in a multi-turn system is thus guaranteed. Thermal protection is provided by the circuit breakers and thermal fuses built into the motor windings.

EX motors are compatible with Parker Servo Drives PSD series and thus offer a complete solution for controlling the motor in ATEX applications.

We also offer a complete drive solution specifically for ATEX applications with ETH actuator and GXA (ATEX) transmission.

To conclude, Parker’s well-known range of ETH electro cylinders for explosive atmospheres are approved for use in explosive gas atmospheres (Group II, Category 2G devices).
