About industrial servo

Types of Industrial Servo

Industrial servo systems are strong mechanisms that help manufacture many products. These help machines like robots, lathes, and conveyor belts move their parts precisely. Just like how a conductor leads an orchestra to play music correctly, industrial servo systems manage machine movements. Some common types include:

Servo Motors

Servo motors are essential electric engines that turn machine parts precisely. Unlike normal motors, these controlled motors can rotate specific amounts and speeds. It helps machines assemble items more accurately than regular motors. They are key in making complex things.

Linear Servos

Linear servo motors are electric machines that move straight instead of turning. They use special parts called lead screws or belt drives to convert turning movement into straight movement. This makes them good for tasks like pushing, pulling, or opening doors that require straight motions. Regular motors can't do these tasks since they only rotate.

Servos with Feedback

Feedback servos are more complex than simple ones. They have sensors that track the motor's position and speed. This information helps the control system keep the motor on the right path. It leads to movements that are even more precise. The feedback makes these systems better for tasks that require more accuracy.

Induction Servos

Induction servos use electromagnetic fields instead of regular motors to control heavy or risky machines. They are more powerful and durable than other servos, able to withstand dirt and weather. They are trusted to control cranes, robots, and other machines that move large objects safely and exactly.

Industrial Servo Materials

Controlling devices in an industrial environment is complex. That's why industrial servo systems consist of multiple intricate parts made of various materials, each chosen for strength, flexibility, and durability. These materials include steel alloys, plastics, copper alloys, aluminum, and ceramics.

Steel Alloys

Steel alloys are critical materials used to make industrial servo systems' gears, shafts, and structural components. Gears are often made of steel alloys, which are further reinforced with carbon. Alloyed carbon also provides extreme wear resistance and tensile strength to the gears.

Further, shafts made of steel alloys provide high torsional strength to transmit motor power effectively. Heat-treated alloy steels are also used for structural components requiring high strength to support the entire system securely.

Plastics

Plastic components are also used in industrial servos to provide lightweight alternatives for certain parts. Usually, polyamide is used to manufacture mid-strength mechanical components like housings, covers, and brackets.

Additionally, the housing is typically made with acrylonitrile butadiene styrene (ABS) or polycarbonate (PC) plastic. These plastics provide impact resistance while still being lightweight. On the other hand, polyoxymethylene (POM), also known as acetal or delrin, is mostly used to make gears and pulleys.

Copper Alloys

Copper alloys like brass and bronze are often used for electrical components within industrial servos. These metal alloys commonly found in automobile brake pads are used for their excellent conductivity. Hence, the copper brass components in the servo motor enable it to function by efficiently transmitting electrical signals.

Additionally, because copper alloys are corrosion-resistant, they work well in electronic components operating in harsh environments. Sometimes, tin-coated copper is also used for wiring, providing a balance of conductivity and corrosion resistance.

Aluminum

Aluminum is commonly used in industrial servos as a lighter manufacturing material for the parts. Usually, it is used to make the casings and external covers of the servo systems. These covers protect internal components without excessively adding weight. The lightweight nature makes it ideal for portable servo systems.

Ceramics

Ceramics are typically employed in industrial servos to isolate the motor from harsh operating conditions. For instance, the insulating stator winding is commonly made from ceramic materials to guarantee highly reliable electrical insulation. In addition, advanced ceramic composites can absorb vibrations, protecting sensitive components.
