Explosion-proof servo motors are electromechanical devices engineered to operate safely in environments where there's risk of explosion due to the presence of flammable gases, vapors, or combustible dust. Their primary purpose is to minimize the potential for sparks, overheating, or any other factors that might trigger an explosion. If an internal explosion occurs, these motors are designed to confine it within their robust casings, preventing the propagation of flames or hazardous materials into the surrounding atmosphere.
The key working principles of explosion-proof servo motors include a combination of features:
The motors are encased in sturdy and tightly sealed housings made of non-sparking materials to prevent the escape of heat or sparks.
Explosion-proof seals are strategically placed to provide maximum protection against hazardous substances entering or leaving the motor.
Thermal protection mechanisms, such as temperature sensors and built-in cooling systems, are integrated to prevent excessive heat generation during operation.
Explosion-proof servo motors find applications in various industries. They are crucial in oil and gas for drilling rigs, offshore platforms, refineries, and petrochemical plants, where flammable gases and vapors are prevalent. In chemical processing facilities handling volatile substances, these motors play a vital role in ensuring safety. The pharmaceutical industry, dealing with flammable dust or vapors, also benefits from the use of explosion-proof motors. Additionally, they are utilized in the food and beverage industry, where combustible dust or gases may be generated during processing.

Kollmorgen's explosion-proof servo motors are well-regarded for their reliability and performance in hazardous environments. The motors undergo rigorous testing and certification to comply with industry standards, ensuring their suitability for hazardous environments. Kollmorgen's commitment to providing excellent technical support and customer service adds value to their products, making them a preferred choice for those seeking reliable and safe explosion-proof servo motors.
Selecting the Right Motor
When selecting an explosion-proof servo motor, it is crucial to consider the specific hazardous environment, motor specifications, and the manufacturer's reputation for quality and safety compliance. By choosing the right explosion-proof motor, industries can ensure enhanced safety, reliability, and regulatory compliance, leading to increased operational efficiency and cost-effectiveness.
Every day Kollmorgen pushes the boundaries of motion to deliver optimized solutions that satisfy even the most demanding application requirements in the harshest of environments. This includes helping machine builders effectively meet the often complex and time-consuming requirements for ATEX certification.
The ATEX certification controls which machinery and equipment are allowed in explosive environments. Industries may include but are not limited to mining, oil and natural gas refining and flour mills.
Ask customers a few open questions to see if they're meeting the criteria:
Does the application environment in which your machine will operate have its own effective source of ignition?
Will the motion components in your machine be used in a potentially explosive atmosphere?
Will your machine operate under normal atmospheric conditions?
If the application meets these criteria, with Kollmorgen they have a market leading option to meet the ATEX certification while also being able to leverage the co-engineering and high performance that Kollmorgen is able to provide.
